庚酸乙酯制备

1.用庚酸与乙醇酯化可以得到含酯量为98%以上的成品。由仲辛醇经硝酸氧化而成己酸和庚酸为主的混合酸，经分馏得庚酸，再和乙醇在硫酸存在下酯化，然后水洗、分馏而得。由庚酸与乙醇直接酯化，反应混合物经水洗后分馏得产品。

2.庚酸银与碘乙烷反应制取。

3.庚酸银与乙醇在硫酸存在下制取。

Effects of droplet crystallization and melting on the aroma release properties of a model oil-in-water emulsion.

J. Agric. Food Chem. 54(5) , 1829-37, (2006)

Aroma compounds partition between the dispersed and the continuous phases in emulsions, and phase transitions in the lipid droplets profoundly affect the position of the equilibrium. In the present st...

Influence of poly (lactide-co-glycolide) type and gamma irradiation on the betamethasone acetate release from the in situ forming systems.

Curr. Drug Deliv. 6(2) , 184-91, (2009)

In situ forming biodegradable polymeric systems were prepared from Poly (DL-lactide-co-glycolide), RG504H (50:50, lactide:glycolide), RG756 (75:25) and mixture of them. They were dissolved in N-methyl...

Identification of electrophysiologically-active compounds for the malaria mosquito, Anopheles gambiae, in human sweat extracts.
