introduction | diethylene glycol dimethyl ether is also called diethylene glycol dimethyl ether, bis (2-methoxyethyl) ether, colorless and transparent liquid. Can be miscible with water, alcohol, ether and hydrocarbon solvents. Diethylene glycol dimethyl ether is an aprotic strong polar solvent, widely used as a solvent, used in the synthesis of organometallic compounds, alkylation reaction, polycondensation reaction; medicine, organic synthesis raw materials. Diethylene glycol dimethyl ether can be prepared by reacting diethylene glycol with methanol. |
use | diethylene glycol dimethyl ether has been widely used as solvent in coatings, medicine, pesticides and other industries mainly used as solvent. Used as a solvent for alkali metal hydroxides in the synthesis of metal organic compounds, alkylation reactions, polycondensation reactions and reduction reactions. Used as a solvent, also used as a pollution-free cleaning agent, extractant, diluent, etc. Used as a solvent, also used in the pharmaceutical industry Used in food additives, medicine, minerals Diethylene glycol dimethyl ether is an aprotic polar solvent, which can be used for polar organic reactions, anionic polymerization, coordination ion polymerization, etc., can be used as a reaction solvent such as reductive alkylation and condensation, and can also be used as Grignite and similar synthesis Medium, it is also used as pollution-free cleaning agent, extractant, diluent, pharmaceutical additive and resin solvent. an aprotic polar solvent |
preparation | add 320ml(256g,8mol) of methanol to a 500ml round bottom flask, install a reflux condenser tube, a calcium chloride drying tube, and slowly add 25g(1.09mol) of sodium metal chips to prepare sodium methoxide solution. After dropping 2,2 '-dichlorodiethyl ether 69g(0.48mol), electromagnetic stirring, heating reflux reaction for 40h. After the reaction is over, a large amount of NaCl solid by-products produced by the reaction are filtered and removed, then methanol is removed by atmospheric distillation, and then 52~65 ℃(2.66kPa) fraction is collected by vacuum distillation. Finally, the collected fractions are subjected to atmospheric distillation to collect fractions at 152~154 ℃(8.13kPa). 51g product was obtained with a yield of 79.3%. |
