| titleOfInvention | Method for directly preparing glycol dimethyl ether and co-producing ethylene glycol from ethylene glycol monomethyl ether |
| abstract | The present invention provides a method for directly preparing glycol dimethyl ether and co-producing ethylene glycol from ethylene glycol monomethyl ether. More specifically, the method comprises passing a feedstock containing a raw material of ethylene glycol monomethyl ether and a carrier gas through a reactor loaded with a solid acid catalyst to produce glycol dimethyl ether and ethylene glycol, at a reaction temperature range from 40°C to 150°C and a reaction pressure range from 0.1 MPa to 15.0 MPa; wherein a carrier gas is an optional inactive gas; and the feedstock contains water whose volume concentration in the feedstock is in a range from 0% to 95%; and the weight hourly space velocity of the raw material of ethylene glycol monomethyl ether is in a range from 0.05h -1 to 5.0h -1 ; and the volume concentration of the raw material of ethylene glycol monomethyl ether in the feedstock is in a range from 1% to 100%; and the volume concentration of the carrier gas in the feedstock is in a range from 0% to 99%. In the method of the present invention, using a solid acid as a catalyst and ethylene glycol monomethyl ether as a raw material, under a low temperature condition, glycol dimethyl ether and ethylene glycol are prepared directly with high selectivity; moreover, there is substantially or completely no production of by-product 1,4-dioxane that causes pollution to the environment and is harmful to the human body or animal bodies. |
