Properties and stability
1. Avoid contact with oxides and moist water.
2. Colorless, odorless, transparent, viscous liquid with hygroscopicity. It has a spicy sweet taste. It is similar to glycol in solubility, but has strong solubility to hydrocarbons. Diethylene glycol can be miscible with water, ethanol, ethylene glycol, acetone, chloroform, furfural, etc. Immiscible with ethyl ether, carbon tetrachloride, carbon disulfide, straight chain aliphatic hydrocarbon, aromatic hydrocarbon, etc. Rosin, shellac, cellulose acetate, and most oils and fats are insoluble in diethylene glycol, but soluble in nitrocellulose, alkyd resins, polyester resins, polyurethane, and most dyes. Flammable, low toxicity. It has the general chemical properties of alcohol and ether.
3. Exist in tobacco leaf and smoke.
use
1. Mainly used as gas dehydrating agent and aromatic hydrocarbon extraction solvent. Also used as a solvent for nitrocellulose, resins, oils, printing inks, softener and finishing agent for textiles, as well as coumarone and indene extracted from coal tar. In addition, diethylene glycol is also used as a brake oil compound, celluloid softener, antifreeze and thinner in emulsion polymerization. Also used in rubber and resin plasticizer; Polyester resin; Fiberglass; Carbamate foam; Lubricating oil viscosity improver and other products production. Used for synthesis of unsaturated polyester resin, etc.
2. Used as synthetic unsaturated polyester resin, plasticizer, etc. It is also used in antifreeze, gas dehydrating agent, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant and finishing agent, paste and all kinds of glue dry-proof agent, VAT dye hygroscopic cosolvent, etc. It is a common solvent for grease, resin and nitrocellulose.
