Introduction
A colorless, odorless, transparent, hygroscopic viscous liquid. It has a spicy sweetness. Its solubility is similar to that of ethylene glycol, but its solubility to hydrocarbons is stronger. Diethylene glycol can be miscible with water, ethanol, ethylene glycol, acetone, chloroform, furfural, etc. It is immiscible with ether, carbon tetrachloride, carbon disulfide, straight chain aliphatic hydrocarbon, aromatic hydrocarbon, etc. Rosin, shellac, cellulose acetate, and most oils are insoluble in diethylene glycol, but can dissolve cellulose nitrate, alkyd resins, polyester resins, polyurethane, and most dyes. Flammable, low toxicity. Having the general chemical properties of alcohol and ether.
Storage Method
1. Store in a cool and dry place. Ensure good ventilation in the workshop.
2. Keep away from fire and water sources. Store away from oxidants
Use
1. Mainly used as gas dehydrating agent and aromatics extraction solvent. It is also used as solvent for cellulose nitrate, resin, grease, printing ink, textile softener, finishing agent, and extraction of coumarone and indene from coal tar. In addition, diethylene glycol is also used as a brake oil complex, celluloid softener, antifreeze and diluent in emulsion polymerization. Also used for rubber and resin plasticizer; Polyester resin; Fiberglass; Carbamate foam; The production of lubricating oil viscosity improver and other products. Used for synthetic unsaturated polyester resin, etc.
2. Used as synthetic unsaturated polyester resin, plasticizer, etc. Also used for antifreeze, gas dehydrating agent, plasticizer, solvent, aromatics extraction agent, cigarette hygroscopic agent, textile lubricant and finishing agent, paste and all kinds of adhesive anti-drying agent, VAT dye hygroscopic solvent, etc. It is a common solvent for grease, resin and nitrocellulose.
