The main products are food processing equipment, wood processing equipment, agricultural equipment, packaging machinery, etc. Our equipment has been widely praised in the domestic and foreign markets.
To manufacture one batch of propylene glycol, the following recipe is proposed: 1. Charge a mixture of 43.04 lbmol of propylene oxide, 802.8 lbmol of water and 71.87 lbmol of methanol, at 77°F, to the reactor over 30 min. The reactor volume is 400 ft3 (D = 8.0 ft, H = 8.0 ft, aspect ratio = 1, which minimizes the purchase . 2 cost). Start the reaction by adding 0.1 wt % (20 lb) of

Little comparison with the homemade batch. First photo is before, second photo is after the addition of a little propylene glycol, and 20-30 minutes of half-assed kneading. The difference is night and day texture-wise. Not the best photo, but it’s as easy to bake now as Swedish match products. Close. 30. Posted by 1 day ago. Little comparison with the homemade batch.
