Description

1. Выход метпловелут по примеру и процесс 29.21 г вого эфира стеариновой кислоты 1,441 (п товарного реактива ( 98%); п2о 1,442). ИК-спектр: 1739 см- (С 0). Пример 5. На 25 г миристата натри  в 100 г абсолютно сухого бутанола действуют 17,6 г сухого брома. Реакционную смесь перенос т в делительную воронку, промывают двум  порци ми (по 100 мл) 5%-кого водного раствора сульфита натри , затем 5%-ным раствором соды и водой до нейтральной реакции. Затем отгон ют избыток бутанола и бутиловый эфир миристиновой кислоты перегон ют в вакууме. Выход 27,80 г (97,9%); п 1,435 (п товарного реактива 1,4349). ИК-спектр: 1738 см-i (С О). Пример 6. Гептиловый эфир масл ной кислоты получают взаимодействием 11,0 г бутирата натри , 80 г гептанола и 17,6 г брома Выход гхчггилбутаиоата 18,29 г по примеру t). (98,3%); «п 1,424 (пл товарного реактива 1,422). ИК-спектр; 1738 см-. П р и м ер 7. К 11,0 г натриевой соли масл ной кислоты в 120 г додецилового спирта прибавл ют 17,6 г брома и действуют по примеру 5. Выход додецилбутаноата 27,86г (98,1%), n-D 1,433 (n-D товарного реактива 1,434). ИК-спектр: 1740см- (С О). Предмет изобретени  Способ получени  сложных эфиров алифатических мопокарбоновых кислот путем взаимодействи  щелочных солей кислот со спиртами с последующим выделением целевого продукта известными приемами, отличающийс  тем, что, с целью упрощени  процесса и повышени  выхода продукта, процесс ведут в присутствии сухого брома.1. The yield of the metal according to the example and the process of 29.21 g of the ester of stearic acid 1,441 (n product reagent (98%); p2o 1,442). IR spectrum: 1739 cm- (C 0). Example 5. Per 25 g of sodium myristate in 100 g of absolutely dry butanol are 17.6 g of dry bromine. The reaction mixture was transferred to a separatory funnel, washed with two portions (100 ml each) of a 5% aqueous solution of sodium sulfite, then with a 5% solution of soda and with water until neutral. The excess butanol is then distilled off and the myristic acid butyl ester is distilled in vacuo. Yield 27.80 g (97.9%); p 1,435 (p commodity reagent 1.4349). IR spectrum: 1738 cm-i (C O). Example 6. Butyl acid heptyl ester is obtained by reacting 11.0 g of sodium butyrate, 80 g of heptanol and 17.6 g of bromine. The yield of ghchggilbutaioate is 18.29 g according to example t). (98.3%); “P 1,424 (product commodity reagent 1,422). IR spectrum; 1738 cm. Example 7. To 11.0 g of sodium salt of butyric acid in 120 g of dodecyl alcohol was added 17.6 g of bromine and operate as in Example 5. The yield of dodecyl butanoate is 27.86 g (98.1%), nD 1.433 ( nD commodity reagent 1,434). IR spectrum: 1740cm- (C O). The subject of the invention is a method of producing esters of aliphatic monocarboxylic acids by reacting alkali salts of acids with alcohols and then isolating the target product with known techniques, characterized in that, in order to simplify the process and increase the yield of the product, the process is carried out in the presence of dry bromine.
