Dipropylene glycol methyl ether is a chemical substance with a molecular formula of C7H16O3. Colorless viscous liquid. Have a pleasant smell. Miscible with water and various organic solvents. It is obtained by hydration of 1,2-propylene oxide to form dipropylene glycol, which is then reacted with methanol. It is mainly used as a solvent for paints and dyes, and also a brake oil component.


Product use of dipropylene glycol methyl ether

It is used as a solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc.; as a solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc., a solvent for paints and dyes, and also a brake oil component. It is used as a solvent for printing inks and enamels, and also as a solvent for cutting oils and working oils. Used as a coupling agent for water-based dilute coatings (usually used in combination).

An active solvent for water-based coatings.

Household and industrial cleaners, grease and coating removers, metal cleaners, solvents for hard surface cleaners and coupling agents.

The basic solvent and coupling agent for solvent-based screen printing inks.

The coupling agent and solvent of the vat dye fabric.

Coupling agents and skin care agents for cosmetic formulations.

Stabilizer for agricultural pesticides.

A coagulant for ground brighteners.


Application field of dipropylene glycol methyl ether

Mainly used as an excellent solvent for nitrocellulose, alkyd resin and maleic anhydride modified phenolic resin, used as an additive for jet fuel antifreeze and brake fluid, etc.; mainly used as solvent, dispersant and diluent, also used Used as fuel antifreeze, extractant, etc.


Method for producing dipropylene glycol methyl ether

1. Hydrogenation of 1,2-propylene oxide to form dipropylene glycol, which is then reacted with methanol.

2. Another method is to react 1,2-propylene oxide with methanol under the catalysis of BF3, adjust the methanol ratio, first hydrolyze to dipropylene glycol, and further react to form the product.


Purification method: fractional distillation.


The above is a brief introduction to the product use, application fields and production methods of dipropylene glycol methyl ether.
