Abstract:
The present invention relates to a process for producing an odorless and colorless industrial grade propylene glycol from glycerol obtained during the manufacturing of biodiesel. The process includes hydrogenating the glycerol to form a hydrogenated product, distilling the hydrogenated product to form a glycol product, and contacting the glycol product with a treatment bed. The propylene glycol may be used in various industrial and consumer applications and products such as personal care products.
