文摘The manufacture of 1,3-propylene glycol through fermentation jointly undertaken by the Tianguan Group of Henan province and the Tsinghua University after passing the smallscale testing has passed the 500 t/a pilot testing in AugustSeptember 2006, which has provided a viable process route for manufacture of 1,3-propylene glycol via the microbial fermentation method. Currently the Tianguan Group is constructing a 1000 t/a 1,3-propylene glycol unit.
