Methoxy propanol (PM)

Methoxy propanol (also known as propylene glycol monomethyl ether, 1-methoxy-2-propanol, PM, and PGME), is a colourless liquid that is soluble in water and is highly flammable. It is a methoxy alcohol derivative and has a formula of C4H10O2.
Methoxy propanol is produced by the reaction of 1,2-epoxy propane and methanol in the presence of a catalyst, and this is then followed by distillation. The worldwide annual production of methoxy propanol is approximately 100,000 to 500,000 tonnes.

Storage

Methoxy propanol has a specific gravity of 0.924 and a flash point of 33° C and is therefore highly flammable so should be stored in a cool, dry and well-ventilated area that is free from sources of ignition. For transport purposes, methoxy propanol is classified as packing group III and hazard class 3 and is an irritant.
