As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. Recommanded Product: (S)-Propane-1,2-diol, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4254-15-3
A (S)- propylene carbonate synthesis method (by machine translation)
The present invention provides a (S)- propylene carbonate synthesis method, comprises a batch charging, temperature reaction, cooling, decompression desolution of the reaction. The invention preparation of (S)- propylene carbonate, yield is 97%; the invention preparation of (S)- propylene carbonate, the specific optical rotation is – 2 – – 3; chemical pure content ? 99.8%; optical pure content ? 99.4%; isomer content ? 0.6%; water content ? 0.1%; the appearance is a colorless clear transparent liquid; from feeding to prepare crude product, the reaction time is 25 hours. (by machine translation)
However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4254-15-3
