Technical Document

Brief Overview 

Mono propylene glycol (also known as propylene glycol, PG, propan1, 2diol, and MPG) is a clear, colorless, and viscous liquid with a characteristic odor which has the formula C3H8O. It is soluble in water and has hygroscopic properties. MPG is used across a wide range of industries due to its low toxicity coupled with a depressed freezing point upon mixing with water.

Manufacturing Process

Mono propylene glycol is produced mainly from propylene oxide. The most common process is the non-catalytic hydrolysis of propylene oxide in a high-temperature and high-pressure environment. The second method is the catalytic method which can proceed at 150 °C in the presence of ion exchange resin or a small amount of sulfuric acid or alkali. Mono propylene glycol can also be produced from glycerol, a bio-diesel by-product.
