Description
Известен способ получени сиитетической винной (виноградной) кислоты (СВК) гидроксилировамием ЗО%-но)Ч) водного patvrBopa Nia.fjenHOBOH кислоты, перекисью водород нри ЬО-80 С и соотношении малеиН1)11а
кисло 1-а : перекис, водорода, равном 1,5: 1.
С целью увеличени выхода iiejieBoio продукта, иредла/аетс процесс гидроксилировами 1 роводигь при увеличении кониент.рации исходной малеиновой кислоты, а тактжк изменении соотношени малеинова кислота: перекись водорода 1:1-1,8, что привод 1т к увеличению выхода СВК до 89,5% а при использовании в реакции вместо раствора малеиновой кислоть малеинового ан гидрида в соотношении с перекисью водорода 1:1,5 выход СВК достигает 93- . 95%.
Зависимость увеличени выходов СВК от концентрации исходной малеиновой кислоты приведена в таблице.
