More Information
Summary:The present invention discloses 2-methyl-2-propyl-1, 3-propylene glycol carbonic diester compound synthesizing process. Inside organic solvent and in the presence of organic amine catalyst, 2-methyl-2-propyl-1, 3-propylene glycol and bis(trichloromehtyl) carbonic ester are reacted at the temperature from -10 deg.c to 120 deg.c; and the resultant is separated and purified to obtain 2-methyl-2-propyl-1, 3-propylene glycol carbonic diester. The process is superior to traditional technological process with hidden danger and serious waste pollution, and has the advantages of high safety, less wastedischarge, high yield, low power consumption, low cost, high product quality, broad industrial application foreground, etc.
