This paper reviews the research and development of phosgene Derivates,including diphenyl ketone,chlorocarbonate,isocya-nate,acyl chloride and carbonates.
The results showed that the main compound categories of aromatic components were alcohols, esters, terpenes and ketones for all half-highbush blueberry cultivars.
The result indicates that the main metabolic product of petroleum hydrocarbon degradation is acetic acid and surface active agent of glycolipid composed of fatty acid and rhamnose.
This work applied the new type capillary column modified by barium sulfate. It has completed the solubilty of high boiling ester in para-methyl-toluate with the method of chromatography.
Dimethyl phenylethyl carbinyl acetate (DPCA ) was synthesized by using a new catalyst. This technology decreases the pollution and can also be used in synthesis of other carbinyl acetates perfume.
The lighter alcohols are the first ones to evaporate during the boiling process, and they're mostly a mixed bag: Esters give off a fruity aroma and were nice to have, but methanol is toxic and not fit for human consumption.
