1, Chemical modification including oxygenation, esterify, graft copolymerization and so on.

2, The tendency of the complexing agent to self—esterify is one of the important Influences.

3, Glycerin was added to esterify with free fatty acids in rice bran oil containing high acid value under the conditions of high temperature, high vacuum and being catalyzed.

4, To produce a high stable L_ascorbic acid 6_palmitate, by the esterify reaction under the conditions of appropriate ingredients, temperature, time and catalyst.

5, The result of FTIR showed the addition of MAPP could esterify the wood flour and make the compatibility between PP and flours better.

6, The effect of reaction timcxreaction temperaturexpH and citrate concentration on the esterify process were discussed.
