FAQ
1, 3-propylene glycol – Why is there no international expansion?
Currently, there are three main methods for producing 1,3-propanediol on the market.
Acrolein process has high raw material cost, heavy pollution, complex separation and easy residual carbonyl compounds, which is not good for polymerization, while the ethylene oxide method was difficult in technology, high equipment investment, catalyst selection and improvement problems. The production of 1, 3-propylene glycol by microbial fermentation mainly has the problems of low product concentration, long production cycle, low production intensity and low conversion rate, which lead to high production cost.
What is 1, 3-propylene glycol used for?
Propylene glycol is a commonly used chemical, mainly used in the manufacture of cosmetics, food, medicine and other products. Its function is as a solvent, regulator, antifreeze and so on.
