Description

Известны способы получени  эфнров коменовой (5-окси-у-пнрон-2-карбоновой ) кислоты в среде серной кислоты.Methods are known for preparing Comenic (5-hydroxy-2-carboxylic) acid efr in sulfuric acid.

Эти способы весьма сложны и не обеспечивают высокого выхода целевого продукта.These methods are very complex and do not provide a high yield of the target product.

По предлагаемому способу, с целью увеличени  выхода и упрощени  технологии, в качестве исходного продукта используют кислый сульфат коменовой кислоты.According to the proposed method, in order to increase the yield and simplify the technology, comenic acid sulphate is used as a starting product.

Реакци  этерификации, осуществл ема  в гомогенной фазе при нагревании реакционной массы на кип щей вод ной бане в течение 2,5-3,0 час, протекает по следующей схеме:The esterification reaction, carried out in a homogeneous phase by heating the reaction mixture in a boiling water bath for 2.5-3.0 hours, proceeds as follows:
