Nature:
1, propylene glycol monomethyl ether is a colorless transparent liquid, with low volatility and toxicity.
2, it is miscible with water and a variety of organic solvents, with good solubility.
Purpose:
1, propylene glycol monomethyl ether is mainly used as a solvent in organic synthesis, can be used to synthesize aliphatic polyether, resin and other chemicals.
2, also used in the preparation of paint, ink, detergent, camphor and other products, in the industry also has cleaning agent, glue removal agent and freezing liquid and other applications.
Preparation:
Propylene glycol monomethyl ether can be synthesized by the reaction of propylene glycol and methanol under the action of acid catalyst. The specific steps include adding propylene glycol and methanol to the reactor, adding an appropriate amount of acidic catalyst, heating and stirring reaction for a certain time, distillation to obtain propylene glycol monomethyl ether product.
Safety information:
1. Propylene glycol monomethyl ether has no obvious harm to the human body under normal conditions, but long-term exposure may cause irritation to the respiratory tract, skin and eyes.
