摘要
猪油在甲酸催化下 ,按H2 O2 /C =C摩尔比为 1 5∶1用双氧水进行原位环氧化。通过考察温度对产物碘值和环氧指数的影响 ,发现随温度的升高 ,产物碘值逐渐减小 ;环氧指数先增大后减小 ,6 3℃时达到最大值。
The effect of temperature on formic acid catalyzed epoxidation of lard that molar ratio of H 2O 2∶C=C is 1.5∶1 was studied.It has been tested that with the increase of the temperature the iodine number decreased and the epoxide value firstly increased and then decreased.When the temperature reached 63 ℃ the epoxide value reached the highest.Some double bonds which took part in oxirane reaction and did not act during the test of iodine number..
