Description
Обычный способ получени стеарина заключаетс , как известно, в том, что жиры расщепл ют сернокислотным или контактным способом , жировые кислоты дестиллируют и дестиллат под вергают двойному (холодному и тор чему), прессованию на гидравлически х прессах . Этот способ в производственном , отношении вл етс сложным, а потери) -в процессе переработки достигают значительных размеров, что невыгодно отражаетс на выходе готового продукта.The usual method of producing stearin is, as is well known, in that fats are split by sulfuric acid or by contact, fatty acids are distilled and the distillate is applied to double (cold and torus) pressing on hydraulic presses. This method is complex in terms of production, and the losses in the process of processing reach considerable sizes, which is unprofitable reflected at the output of the finished product.
Известно также получение стеарина путём омылени гидрированных жиров известью (по Кребицу) с последующим разложением кальциевых мыл кислотой. Этот способ обладает следующими преимуществами по срав«ен«ю с контактным.It is also known to obtain stearin by saponifying hydrogenated fats with lime (according to Krebitz) with the subsequent decomposition of calcium soaps with acid. This method has the following advantages in comparison with the contact.
1.Так как омыление по методу Кребица производитс без кип чени , а лишь нагреванием жира до 95-100°, .расход пара совершенно ничтожен по оравнению с контактHbiiM расщеплением, при кото:ром жир кип титс в течение 20-24 часов .1. Since the Krebitz saponification is carried out without boiling, but only by heating the fat to 95-100 °, steam consumption is completely insignificant by comparison with the HbiiM splitting contact, for which: rum fat boils for 20-24 hours.
2.Отпадает доротой и св занный с потер ми процесс прессовани .2. It disappears with expensiveness and lossy pressing process.
3.После обработки кислого водного раствора известью и упадки3. After processing the acidic aqueous solution of lime and decay
получаетс высокого качества глицерин с большим выходом, так как расщепление идёт почти на 100%, а не на 92-95%, как при контактном методе.High quality glycerin is obtained with a high yield, since the splitting goes by almost 100%, and not by 92-95%, as in the contact method.
Предлагае.юе изобретение относитс к получению стеарина путём омылени жиров известью с последующим , разложением кальциевых мыл.The present invention relates to the preparation of stearin by the saponification of fats with lime, followed by the decomposition of calcium soaps.
Автором установлено, что дл получени .в:ысоко«ачестве-нн€го продукта , не требующего дестилл ции, омылению «звестью следует подвергать гидрированные до титра 52-54 растительные масла. При этом получаетс продукт, почти не уступающий по цвету прессовому стеарину.The author has established that in order to obtain .c: High quality of a product that does not require distillation, saponification of a vegetable oil 52-54 hydrogenated to a titer should be subjected to a star. This produces a product that is almost the same as pressed stearin.
в процессе разложени известковых мыл кислото целесообразно примен ть вместо разбавленно серной кислоты кислую глицериновую воду, получаемую при расщеплении контактным -методом. Так как дл нейтрализации кислых глицериновых вод обычно употребл етс известь, то .применение кислой глицериновой воды дл разложени мыл приводит к одновременной экономии серной кислоты и извести. Кроме того весь глицерин , содержащийс в известковых мылах, переходит в глицериновую воду, повыша её концентрацию . Благодар этому сокращаетс расход пара на упарива-ние глицериновой воды.In the process of decomposition of lime acid soaps, it is advisable to use, instead of dilute sulfuric acid, acidic glycerin water obtained by splitting by the contact γ-method. Since lime is usually used to neutralize acidic glycerol waters, the use of acidic glycerinic water for the decomposition of soaps leads to simultaneous savings of sulfuric acid and lime. In addition, all the glycerin contained in lime soaps, goes into glycerin water, increasing its concentration. Due to this, steam consumption for evaporation of glycerin water is reduced.
