1. To indicate the feasibility of using acetic ester carboxylation process in China based on making process comparison.

2. Some kinds of reactions such as acylation , carboxylation , etheration, N-alkylation, esterification ect. and their derivates' prospect applications are especially discussed.

3. In short supply of water, leaf carboxylation efficiency and apparent quantum yield were cut down.

4. The industrialized methods of sodium cyanide , phenylacetamide, carboxylation are compared.

5. Severe water stress inhibited photosynthetic quantum yield, carboxylation efficiency, electron transport rate, and photophosphorylation activity.

6. To indicate the feasibility of acetic ester carboxylation process in China based on making process comparison.

7. Glycerate 3-phosphate is the first product of the dark reactions of PHOTOSYNTHESIS, formed by the carboxylation and cleavage of ribulose bisphosphate.

8. The accepted commercial process is based on 2, 4 - difuloroaniline, through coupling , acylation, hydrolysis and carboxylation reactions.
