| | Dipropylene glycol monomethyl ether Usage And Synthesis |
| Chemical Properties | Dipropylene glycol monomethyl ether (DPM) is colorless liquid with a mild, pleasant odor. Because of its structure it is completely miscible with water and a wide variety of organic substances, and has the combined solubility characteristics of an alcohol, on ether and a hydrocarbon. It is used in formulations of brake fluids, lacquers, paints, varnishes, dye and ink solvents, wood stains, textile processes, dry cleaning soaps and cleaning compounds.
| | Characteristics | Dipropylene glycol methyl ether is a colorless transparent liquid with a faint ether smell. Dipropylene glycol methyl ether has low toxicity. Dipropylene glycol methyl ether has low viscosity and low surface tension. Dipropylene glycol methyl ether has a moderate evaporation rate. Dipropylene glycol methyl ether has good solubility and coupling ability.
Dipropylene glycol methyl ether is miscible with water and has appropriate HLB value. It can dissolve grease, natural resin and rubber, cellulose, polyvinyl acetate, polyvinyl methyl/ethyl/butyraldehyde, alkyd resin, phenolic resin, Polymer chemicals such as urea resin. | | Uses | Dipropylene glycol methyl ether is used as a solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc.; as a solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc., as a solvent for paints and dyes, and also as a brake oil components. It is used as a solvent for printing ink and enamel, and also as a solvent for washing of cutting oil and working oil. Used as a coupling agent for water-based dilution coatings (often mixed).
Dipropylene glycol methyl ether can be used as an active solvent for water-based coatings. Dipropylene glycol methyl ether can also be used as a solvent and coupling agent for household and industrial cleaners, grease and paint removers, metal cleaners, hard surface cleaners; dipropylene glycol methyl ether can be used as a base for solvent-based screen printing inks Solvent, coupling agent; dipropylene glycol methyl ether can be used as coupling agent and solvent for vat dye fabrics; dipropylene glycol methyl ether can be used as coupling agent and skin care agent in cosmetic formulations; dipropylene glycol methyl ether can be used as agricultural insecticide Stabilizer of agent; Dipropylene glycol methyl ether can be used as coagulant of ground brightener. | | Uses | Dipropylene Glycol Monomethyl Ether is used in preparation of special cleaning agent for pot bottom black dirt. | | Uses | Solvent for nitrocellulose and synthetic
resins | | Uses | As solvent for automotive fluids, cleaners, dyes, coatings, inks, waxes, adhesives, agricultural products, insect repellents, and cosmetics; chemical intermediate. | | Uses | Dipropylene glycol methyl ether is often used in
combination with propylene glycol in cosmetics. | | General Description | Colorless liquid with a weak odor . | | Air & Water Reactions | Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Miscible with water. | | Reactivity Profile | Dipropylene glycol monomethyl ether may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides. | | Health Hazard | CALL FOR MEDICAL AID. LIQUID: Irritating to skin and eyes. Harmful if swallowed. Remove contaminated clothing and shoes. Flush affected areas with plenty of water. IF IN EYES, hold eyelids open and flush with plenty of water. May be harmful by inhalation, ingestion, or skin absorption. May cause irritation. | | Fire Hazard | Combustible. Emits toxic fumes under fire conditions. | | Flammability and Explosibility | Nonflammable | | Safety Profile | fddly toxic by
ingestion and skin contact. An experimental
skin and human eye irritant. A dd allergen.
Combustible when exposed to heat or
flame; can react with oxidizing materials. To
fight fire, use dry chemical, CO2, mist, foam.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
