1) A stereoselective hydrolysis of the racemic naproxen methyl ester by immobilized lipase from Candida rugosa in a low aqueous organic biphase system was studied.

2) Results Atro-pine, diethylamine methyl ester hydrochloride and tetrodotoxin could abolish the excitatory role of somatostatin on the sphincter.

3) The research is about united manufacture of methyl ester of dichloroacetic acid and mercaptoacetic acid, using mother solution of monochloroacetic acid and sodium sulfhydrate as materials.

4) Methods:Chiglitazar was synthesized from 2-(4-fluoro)benzoylcyclohexanone, L-tyrosine methyl ester and 1,2-dibromoethane via 3 steps.

5) Sulfonated fatty acid methyl ester surfactant is purified by two - step solvent crystallization.

6) The structures of etodolac and its methyl ester were the same as those reported in literature.

7) The isomerization of methyl ester of cottonseed oil by the catalyst iodine was investigated.

8) A new process has been developed to synthesize dimethoxy methyl acetoacetate with dimethoxyacetic acid methyl ester and methyl acetate in the presence of sodium methanol.

9) Methods: acid react with methyl alcohol and alcohol to synthesize methyl ester and ethyl ester compounds.

10) Among those, 2,4-Decadienal,(http://sentencedict.com/methyl ester.html) Hexadecanoic acid ethyl ester and Hexadecanoic acid methyl ester were found from the oil in Ziziphus jujuba Mill.

11) In the process glyceride is transformed into fatty acid methyl ester and glycerol by - product.

12) The process of this method is relatively complicated, its advantage is vicinal diol's total selectivity reached 85%, when the conversion rate of unsaturated fatty acid methyl ester was 98%.

13) Preparation of azelaic acid monomethyl ester by ozonolysis reaction from oleic acid methyl ester was studied.

14) PME, which is belong to saponifcational enzyme, can randomly hydrolyze the methyl ester bond of pectin.

15) Cocoa butter equivalent(CBE)production from palm oil m idfraction(POMF)and stearic acid methyl ester(SAME)by interesterification catalyzed by 1,3 specific lipases in solvent free system was studied.

16) Methods ? ? - Ty - Folate was synthesized by conjugating folic acid to tyrosine methyl ester through EDC and hydrolyzing.

17) The immobilized enzyme from Bacillis megaterium gave a better catalytic properties and the higher conversion was obtained using phenylglycine methyl ester (PGME) as acyl donor.

18) They were acetic acid, benzaldehyde, n caproic acid, 14 methyl pentadecanoic methyl ester, glycerin, benzoic acid, 6,9 octadecadienoic methyl ester, squalane, stearic acid and oleic eicosyl ester.

19) Conclusion The main chemical components of the fatty oil in Carum carvi L. were dibutyl phthalate, octadecanoic acid methyl ester, eicosanoic acid methyl ester, he...
