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 A known method for producing sythitic tartaric (grape) acid (SCD) by hydroxylation of ZO% but H) aqueous patvrBopa Nia.fjenHOBOH acids, hydrogen peroxide at H-80 ° C and the ratio of H1) 11a
кисло 1-а : перекис, водорода, равном 1,5: 1.sour 1-a: peroxide, hydrogen, equal to 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%.In order to increase the yield of iiejieBioio product, the hydrodilution process is carried out with an increase in the concentration of the initial maleic acid, and a tactical change in the ratio of maleic acid: hydrogen peroxide 1: 1-1.8, which drives 1t to an increase in the output of the ICS to 89 5% and when used in the reaction instead of a solution of maleic acid, maleic anhydride in relation to hydrogen peroxide 1: 1.5, the yield of CBC reaches 93-. 95%.
Зависимость увеличени выходов СВК от концентрации исходной малеиновой кислоты приведена в таблице.The dependence of the increase in the yields of the ICS on the concentration of the initial maleic acid is given in the table.
