Estabilizacion de acidos ftalimido percarbox^licos con sales de litio Campo de la invencionStabilization of phthalimide percarboxylic acids with lithium salts Field of the invention

La presente invencion se refiere a una mezcla para su uso como un agente blanqueador que comprende al menos un acido ftalimido percarbox^lico y al menos una sal de litio inorganica, a una composicion detergente que comprende dicha mezcla y al uso de al menos una sal de litio para estabilizar un acido ftalimido percarboxflico en una composicion detergente.The present invention relates to a mixture for use as a bleaching agent comprising at least one phthalimide percarboxylic acid and at least one inorganic lithium salt, a detergent composition comprising said mixture and the use of at least one salt. of lithium to stabilize a phthalimide percarboxylic acid in a detergent composition.

Antecedentes de la invencionBackground of the invention

En el pasado, los peracidos organicos han encontrado un interes creciente en el campo industrial, entre otras cuestiones debido a sus excelentes propiedades como agentes blanqueadores en formulaciones detergentes. Por lo tanto, un gran numero de publicaciones estan relacionadas con compuestos de peracido organicos dotados de la propiedad requerida de actividad blanqueadora suficiente, siendo esencial dicha caractenstica para una aplicacion industrial y un uso extendido de tales compuestos. De esta manera, se conocen y usan muchos acidos organicos mono- o di-percarboxflicos, de cadena lineal o dclicos, por ejemplo en composiciones detergentes.In the past, organic perazides have found a growing interest in the industrial field, among other issues due to their excellent properties as bleaching agents in detergent formulations. Therefore, a large number of publications are related to organic perazide compounds endowed with the required property of sufficient bleaching activity, said feature being essential for an industrial application and extended use of such compounds. In this way, many mono- or di-percarboxylic, straight chain or dical organic acids are known and used, for example in detergent compositions.

Un problema con el uso extendido de peracidos organicos surge a partir de su baja estabilidad termica, que hace necesario estabilizar ffsica o qmmicamente estos compuestos. Los peracidos organicos conocidos hasta ahora muestran una disminucion significativa del oxfgeno activo, incluso en condiciones de almacenamiento convencionales. Este tambien es el caso con los acidos imido percarboxflicos, como ya se ha descrito en Chem. Soc. 1962, 3821 y Chem. Ind. 1961,469. Entre los acidos imido percarboxflicos, los acidos ftalimido percarboxflicos han conseguido un uso extendido en la industria, especialmente como agentes blanqueadores en composiciones detergentes. Sin embargo, la adiccion de acido borico a los acidos ftalimido percarboxflicos se considera necesaria para garantizar una estabilidad a largo plazo suficiente.A problem with the widespread use of organic peraids arises from their low thermal stability, which makes it necessary to physically or chemically stabilize these compounds. The organic peraids known so far show a significant decrease in active oxygen, even under conventional storage conditions. This is also the case with the imido percarboxylic acids, as already described in Chem. Soc. 1962, 3821 and Chem. Ind. 1961,469. Among the imido percarboxylic acids, phthalimido percarboxylic acids have achieved widespread use in industry, especially as bleaching agents in detergent compositions. However, the addition of boric acid to phthalimide percarboxylic acids is considered necessary to ensure sufficient long-term stability.

Puesto que el acido borico se ha convertido en una sustancia qmmica de gran preocupacion, cabe esperar que se prohfba el uso de acido borico en aplicaciones domesticas en el futuro proximo. En consecuencia, hay necesidad de maneras alternativas de estabilizar los acidos ftalimido percarboxflicos en composiciones detergentes sin usar acido borico.Since boric acid has become a chemical of great concern, it is expected that the use of boric acid in domestic applications will be banned in the near future. Consequently, there is a need for alternative ways of stabilizing phthalimido percarboxylic acids in detergent compositions without using boric acid.

Sumario de la invencionSummary of the invention

La presente invencion satisface esta necesidad proporcionando una mezcla para su uso como un agente blanqueador que comprende al menos un acido ftalimido percarboxflico y al menos una sal de litio inorganica. Con la presente invencion, es posible estabilizar acidos ftalimido percarboxflicos para minimizar una disminucion del oxfgeno en condiciones de almacenamiento convencionales, para evitar el uso de acido borico. De esta manera, pueden obtenerse composiciones detergentes que muestran una actividad blanqueadora suficiente con el tiempo.The present invention satisfies this need by providing a mixture for use as a bleaching agent comprising at least one phthalimide percarboxylic acid and at least one inorganic lithium salt. With the present invention, it is possible to stabilize phthalimide percarboxylic acids to minimize a decrease in oxygen under conventional storage conditions, to avoid the use of boric acid. In this way, detergent compositions can be obtained that show sufficient bleaching activity over time.

Descripcion detallada de la invencionDetailed description of the invention

Despues de estudios extensivos, los inventores han encontrado que los acidos ftalimido percarboxflicos pueden estabilizarse mediante sales inorganicas de litio. Esto es bastante sorprendente, puesto que la tecnica anterior sugena que, si no se estabilizaban, los acidos ftalimido percarboxflicos se degradaban siguiendo una ruta de reaccion por radicales.After extensive studies, the inventors have found that phthalimide percarboxylic acids can be stabilized by inorganic lithium salts. This is quite surprising, since the prior art suggests that, if they were not stabilized, phthalimide percarboxylic acids were degraded following a radical reaction path.

Sin desear quedar ligado a teona alguna, se supone que los acidos ftalimido percarboxflicos, de hecho, se degradan por el ataque de nucleofilos. En la figura 1 se muestra un esquema de degradacion plausible del acido ftalimido peroxihexanoico (acido ftalimido percaproico, PAP) en condiciones alcalinas. De acuerdo con la figura 1, el PAP se degrada a 4-ftalimido-1-hexanol y dioxido de carbono por reaccion electrodclica. En consecuencia, la presencia de al menos una sal de litio evitana que los nucleofilos degradaran el PAP, ya sea excluyendo los nuecleofilos reactivos, bloqueando sitios de reaccion nucleofilos en el PAP y/o captando nucleofilos con electrofilos distintos de PAP.Without wishing to be bound to any theone, it is assumed that phthalimide percarboxylic acids, in fact, are degraded by the attack of nucleophiles. A plausible degradation scheme of peroxyhexanoic phthalimido acid (percaproic phthalimido acid, PAP) in alkaline conditions is shown in Figure 1. According to Figure 1, the PAP is degraded to 4-phthalimido-1-hexanol and carbon dioxide by electrodic reaction. Consequently, the presence of at least one lithium salt will prevent the nucleophiles from degrading the PAP, either by excluding the reactive nucleophiles, blocking nucleophilic reaction sites in the PAP and / or capturing nucleophiles with electrophiles other than PAP.

Por lo tanto, la presente invencion se refiere a una mezcla para su uso como un agente blanqueador que comprende al menos un acido ftalimido percarboxflico y al menos una sal de litio inorganica.Therefore, the present invention relates to a mixture for use as a bleaching agent comprising at least one phthalimide percarboxylic acid and at least one inorganic lithium salt.

No hay restriccion respecto a la naturaleza qmmica de la al menos una sal de litio. De esta manera, la al menos una sal de litios es inorganica. Aparte, la al menos una sal de litio puede ser hfdrica o anhidra.There is no restriction regarding the chemical nature of the at least one lithium salt. In this way, the at least one lithium salt is inorganic. In addition, the at least one lithium salt can be water or anhydrous.

Por lo tanto, la presente invencion se refiere tambien a la mezcla descrita anteriormente, caracterizada por que comprende al menos una sal de litio inorganica.Therefore, the present invention also relates to the mixture described above, characterized in that it comprises at least one inorganic lithium salt.

EjemplosExamples

Ejemplo 1:Example 1:

Una mezcla para su uso como un agente blanqueador que comprende 86 % en peso de acido ftalimido peroxihexanoico (acido ftalimido percaproico, PAP) y 14% en peso de un agente estabilizador (ejemplo 1a: acido borico (comparativo); ejemplo 1b: sulfato sodico (comparativo); ejemplo 1c: sulfato de litio) se ensayo para su estabilidad a largo plazo. Por lo tanto, la cantidad de PAP qmmicamente activo en la mezcla respectiva se determino despues del almacenamiento a 40 °C a los 1, 3, 7, 14, 21,28, 49, 84, 119, 161 y 210 dfas, respectivamente.A mixture for use as a bleaching agent comprising 86% by weight of phthalimido peroxyhexanoic acid (phthalimide percaproic acid, PAP) and 14% by weight of a stabilizing agent (example 1a: boric acid (comparative); example 1b: sodium sulfate (comparative); example 1c: lithium sulfate) was tested for long-term stability. Therefore, the amount of chemically active PAP in the respective mixture was determined after storage at 40 ° C at 1, 3, 7, 14, 21,28, 49, 84, 119, 161 and 210 days, respectively.

Como puede verse en la tabla 1, una mezcla que comprende sulfato de litio (ejemplo 1c) muestra una estabilidad a largo plazo significativamente mayor del acido ftalimido peroxihexanoico (acido ftalimido percaproico PAP) que una mezcla que comprende sulfato sodico (ejemplo 1b).As can be seen in Table 1, a mixture comprising lithium sulfate (example 1c) shows significantly greater long-term stability of the peroxyhexanoic phthalimido acid (PAP percaproic phthalimido acid) than a mixture comprising sodium sulfate (example 1b).

Ademas, como puede verse en la figura 2, el acido ftalimido peroxihexanoico (acido ftalimido percaproico, PAP) puede estabilizarse aun mas eficazmente mediante una sal de litio de acuerdo con la presente invencion (ejemplo 10 1c) que mediante el acido borico usado convencionalmente (ejemplo 1a).In addition, as can be seen in Figure 2, peroxyhexanoic phthalimido acid (percaproic phthalimido acid, PAP) can be stabilized even more efficiently by a lithium salt according to the present invention (example 10 1c) than by conventionally used boric acid ( example 1a).
