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:
