preparation

In industry, propylene oxide is isomerized to produce allyl alcohol, and then through hydroformylation reaction, methyl propylene glycol is synthesized.

Characteristics and uses

Methylpropylene glycol is a low molecular weight and high boiling point diol containing 2 primary hydroxyl groups and lateral methyl groups. It is liquid at room

temperature. Compared with neopentanediol, it is easy to measure and pump, and it is easy to operate and has a wide range of application.

In the field of polyurethane, it is used to produce polyester polyols with low crystallization, and can be used as chain extender. The application fields are synthetic

leather paste, polyurethane coating, polyurethane adhesive for food flexible packaging composite.

Toxicity and protection

Methylpropylene glycol is almost non-toxic, non-irritating to the skin and eyes, and is approved by the FDA.
