nature
Colorless transparent liquid with pleasant odor, poisonous. The relative density is 0.9647. Boiling point (102.391kPa) 125ºC, melting point -85.1 ºC. Flash point 46.1 ° C. Refractive index 1.4024. Spontaneous combustion point 288.3ºC. Miscible with water, ethanol, ether, glycerol, acetone, N, N-dimethylformamide.
preparation
First, methanol is put into boron trifluoride monoethyl ether complex, and slowly passes into ethylene oxide under stirring, so that ethylene glycol monomethyl ether is generated, and alkali is added to neutralize, excess methanol is distilled at atmospheric pressure and recovered, and the required product is steamed under reduced pressure.
use
Solvents for oils and fats, cellulose nitrate, alcohol-soluble dyes and synthetic resins, reagents for determination of iron, sulfate and carbon disulfide, quick-drying solvents for enamels and varnishes, diluents for coatings, penetrants and levelling agents in the dye industry. It is also used to prepare sealants. As an intermediate in the production of organic compounds, ethylene glycol monomethyl ether is mainly used in the synthesis of acetate and ethylene glycol dimethyl ether. It is also a raw material for the production of di (2-methoxyethyl) phthalate plasticizers. In addition, it can also be used as an antifreeze additive for military jet dyes..
