Dipropylene Glycol is a co-product from the manufacture of monopropylene glycol, involving the high temperature and high pressure hydrolysis of propylene oxide (PO) with excess water. 

Dipropylene glycoltechnical grade is a distilled product of greater than 99% purity (as DPG).

Characteristic:

Colorless

Practically odorless

Water soluble

Medium viscosity

Hygroscopic liquid

Low vapor pressure 

Low toxicity

Quick Detail
1. DPG,Dipropylene Glycol

2. Mixture of structural isomers

3. Dipropylene glycol technical grade

Applications:

Dipropylene Glycol Technical Grade is used as a solvent, coupling agent and chemical intermediate.

Typical applications include:

1. Esterification with benzoic acid to make dipropylene glycol dibenzoate for plasticizers. 

2. A reactant in unsaturated polyester resins to add flexibility and hydrolytic stability to the finished resin. 3. Esterification with acrylic acid to make dipropylene glycol diacrylate for radiation cured resin formulations. 

4. In dicyclopentadiene-based unsaturated polyester resin systems to add flexibility. 

5. An initiator for urethane polyol synthesis using epoxides, and for the polyol in rigid polyurethane foams.

 Dipropylene Glycol’s excellent solvency for certain oils, low evaporation rate and low toxicity lend its use in brake fluid formulations, cuttings oils, textile lubricants, printing inks, coatings, industrial soaps and as a solvent for agricultural and insecticidal formulations.
