With Malania oleifera oil as raw material and nervonic acid content as index,the effects of mass fraction of Na OH solution,ratio of liquid to solid,saponification temperature and saponification time on the saponification of nervonic acid glyceride from Malania oleifera oil were studied by single factor experiment. Then the saponification conditions were optimized by response surface methodology as follows:mass fraction of Na OH solution 25%,ratio of liquid to solid 1 ∶ 1,saponification temperature 90 ℃ and...
