SU12226A1 - The method of preparation of dry and durable during storage of soap - Google Patents

Description

The proposed method of preparing dry and sturdy soaps suitable for final cold processing relates to saponification methods, with stirring with soda, fatty acids obtained by strong cleavage or distillation, with or without added fat dissolving substances. . Strong when storing soap contain large amounts of fatty acids and a small amount of water. The best content of fatty acids in them is 79-80%. If you replace the water in the soap with all or part of sodium bicarbonate, you can get well sawn and durable soap with a fatty acid content between 60 and 65%. The way to make sodium bicarbonate-containing soap consists of directly affecting soda-free fatty acids on soda, and if you take one molecule of fatty acids and no more than one soda, you have the following reaction:

RCOOH - | - MAGSOZ RCOONa + NSOZ

/ The author found that, if fatty acids that do not contain neutral fats, lead all interactions with one soda molecule at a temperature

above the melting point of fatty acids, then by adding a liquid or solid wood or glue soap before or after the saponification is completed, a soap mixture is obtained that is easily and well treated and which has all the desired qualities in terms of strength, uniformity, weight and shape stability. . The method consists in that soda ash, with a water content of not more than 30% of its weight, is mixed with fatty acids until a homogeneous mass is formed. Soda is taken in an amount theoretically necessary for saponification or in excess of not more than 100%. Liquid or solid wood or glue soap is added to the resulting mass. This additive is introduced before or after the end of the saponification or after grinding the main saponified mass. The mixture is thoroughly mixed until uniform and then cold worked. Example 1. 1000 kg of palmwood fatty acid or coconut oil split more than 99 ° / o are mixed with 360 kg of soda ash and a homogeneous mass is obtained, which after some time is washed from self-heating. Before passing the washing process to the end and until the final curing of the mass

700-800 kg of liquid wood soap made of lard or bone fat is added, and thus with appropriate stirring, after a short period of time, an almost homogeneous soap is obtained, which in rolling rollers after an hour is rolled into strips that can be either immediately or after pressing for some time, shape the cores and then subject to further processing.

Example 2. 1000 WZ split more than more than a mixture consisting of: 30Vo palmwood fatty acid, palm oil fatty acid, 40% fatty acid from fat, is mixed with 350 kg of soda ash at 30-35 °. Initially, the completely liquid mass heats up after a short time and becomes solid, after which the temperature rises to 60-65 °. After a few hours, the wash is finished and the mass at 40-50 ° C is diluted with distilled water to transparency. After that, it is ground in suitable mills and then mixed with liquid or solid wood soap. For this purpose, 400 K1 of n-level wood soap is added to the mixer and 600 kg of the above ground powder of high-grade soap are added gradually. After 5, maximum

10 minutes, an almost completely homogeneous product is obtained. Through a single pass between the rollers, this product turns into strips and, when sawing, produces perfectly uniform rods, which in appearance do not reveal any difference from the usual best grades: they are easily cut and pressed.

The subject of the patent.

A method for preparing dry and durable soaps suitable for final cold treatment, by saponification, with stirring with soda, fatty acids obtained by strong cleavage or distillation, with or without the addition of a substance of lower fats, such as soda ash , dry or wet with a water content of not more than 30% of its weight, take in an amount theoretically necessary for saponification or in excess of no more than lOOVo and mix closely with fatty acids until a homogeneous mass of soap is added to not finished adhesive or kernel soap, liquid or solid, after saponification or after milling or after omylivsheys primary mass and the mixture was subjected to treatment by cold.
