Definitions
- This invention relates to catalysts and more particularly to catalysts for producing alkyl substituted pyrrolidones from alcohols and 2-pyrrolidone.
- N-substituted 2-pyrrolidones are produced by the reaction of butyrolactone with the corresponding amine.
- amines are more costly than corresponding alcohols since they are prepared from the alcohols, requiring an extra processing step.
- the amines are produced in less than quantitative yields due to the formation of secondary and tertiary amines. Consequently, it would be economically desirable- to prepare N-substituted pyrrolidones directly from alcohols and 2- pyrrolidone, providing the yields are sufficiently high.
- a method which utilizes copper catalysts in a hydrogen atmosphere at temperatures of 180 to 450°C to react various alcohols with 2-pyrrolidone.
- the catalysts discussed are copper, copper-chromium, copper- rhenium, copper-silver, copper-nickel, copper-molybdenum, copper-manganese, copper-tungsten, and a copper-chromium- manganese catalyst. These were found to provide satisfactory selectivity relative to alcohol and pyrrolidone, however the yields were fairly low.
- a catalyst for converting various alcohols and cyclic lactams to N-substituted cyclic lactams in a hydrogen environment comprises from 10 to 15% cooper, 0.01 to 0.15% palladium disposed on a carrier. Utilizing a copper-palladium catalyst produces noticeable improvements in yield and selectively over other catalysts, including those disclosed in the Japanese Application, particularly in the production of N-octyl 2- pyrrolidone. DETAILED DESCRIPTION OF THE INVENTION
- the active catalytic components according 'to the present invention are copper and palladium deposited on a substrate support material. While various substrates could be used, a manganese silicate support substrate is preferred.
- the active catalytic material copper and palladium
- the active catalytic material are deposited on the substrate material by any conventional method.
- metal salts are dissolved in either aqueous or organic solvents and dried on a substrate and then treated with hydrogen to form metal crystallites. While metal deposition from the nitrates is preferred, any acceptable route to form the metal crystallites on the substrate material may be used, such as hydrogen reduction of the salt to form the metal crystallites or oxidation of the salt in air followed by reduction in hydrogen.
- the amounts of copper and palladium used may vary somewhat but are generally used in amounts based on catalyst plus support materials of 10 to 15% by weight copper, 0.01 to 0.15% palladium. Preferably, 10 to 12% copper and 0.09 to 0.13% palladium are used.
- the catalyst is usable at temperatures of from about 150° to 400°C.
- the inventive catalyst provides improved conversion and selectively in the conversion of alcohols and cyclic lactams of the Formula I to produce N-substituted lactams of the Formula II:
- n is an integer from 2 to 20.
- 2-pyrrolidone of Formula III is used, to produce the N-substituted pyrrolidones of Formula IV:
- R', R" and R 1 are H or lower alkyl
- R IV is
- n 2 to 20.
- the reactions described in the example can be varied to alter the characteristics of the catalyst. Longer reaction times and higher temperatures may produce catalysts which have an increase in effectiveness as it was found that during the initial reaction with copper nitrate, the longer reaction times, higher temperatures and higher acid levels may result in the production of a catalyst which has copper disposed deeper in the substrate. This tends to induce a stronger interaction of the copper with the substrate which increases the efficiency of the catalyst when used in the reaction of the invention.
- a reaction was also carried out as described in example 2 using copper chromite and ruthenium catalysts as described in Table II which follows. Conditions such as pressure, temperature and time were also varied. The best results were obtained at a hydrogen pressure of 1,000 psi where the selectively was 50% and the yield was 39.7%. In addition, Raney copper, and copper-bismuth were also utilized, none of which were as effective as even the copper chromite catalyst.
- inventive catalyst economic conversion of alcohols and 2-pyrrolidone or cyclic lactams to corresponding alkyl pyrrolidones and alkyl substituted lactams are achieved.
- inventive process processing costs are reduced through the reduction in cost of raw materials for producing the finished product. For example, octylamine sells for approximately $2.50/pound while octyl alcohol sells for approximately $.83/pound.
- the invention offers significant improvements over the prior art processes for producing N-substituted pyrrolidones. While preferred embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications could be made without varying from the scope of the present invention.

Abstract
L'invention se rapporte à un catalyseur et à un procédé de production de pyrrolidones substituées par N. Ce procédé met en oeuvre un catalyseur de cuivre-palladium placé sur un support et mélangé à un alcool désiré et à 2-pyrrolidone. On effectue une réaction dans une atmosphère d'hydrogène, de préférence de 50 à 1000 psig, et à une température s'élévant jusqu'à 400 °C. En utilisant un catalyseur de cuivre-palladium, on obtient des résultats supérieurs au niveau de la sélectivité et du rendement par rapport aux catalyseurs précédents.
