Application of 1,3-PDO, Production of 1,3-PDO
1,3-PDO is the monomer of polytrimethylene terephthalate.
It is widely used as the raw material of cosmetics, food, textile, lubricants, and medicines.
The yield of chemical method to produce 1,3-PDO is low, and there are many by-product by using chemical production of 1,3-PDO. As a result, it is difficult to produce 1,3-PDO by chemical method.

Furthermore, the economy of the ethanol production process from grains depends on the market for its by-product, i.e. distillers' dried grains with solubles (DDGS) as animal food, which may not expand like the ethanol market in the future. In addition to the price, there is concer
