Purpose:
1. It is mainly used as gas dehydrator and aromatic extraction solvent. It is also used as solvent of nitrocellulose, resin, grease, printing ink, softener and finishing agent of textiles, and extraction of coumarin and indene from coal tar. In addition, two glycol is also used as brake oil mixture, celluloid softener, antifreeze and diluent during emulsion polymerization. It is also used in rubber and resin plasticizers; polyester resins; fiber glass; carbamate foam; lubricating oil viscosity improver and other products. It can be used to synthesize unsaturated polyester resin.
2. Used for synthesis of unsaturated polyester resin, plasticizer, etc. It is also used in antifreeze, gas dehydrating agent, plasticizer, solvent, aromatic extraction agent, cigarette hygroscopic agent, textile lubricant and finishing agent, anti drying agent of paste and various gums, moisture absorption auxiliary solvent of vat dyes, etc. It is a common solvent for oil, resin and nitrocellulose.
