    摘要： An improved method for recovering a purified polyether polyol comprising the steps of providing an aqueous solution of a polyether polyol containing an alkali metal catalyst residual formed from a transesterification process, contacting the aqueous solution with a stoichiometric excess of magnesium sulfate to form a second aqueous solution, removing water from said second aqueous solution at a temperature above the melt temperature of said polyether polyol to produce a dehydrated slurry containing a molten polyether polyol phase essentially free of residual alkali metal and a precipitated solid phase comprising sulfate and/or sulfite salts of the alkali metal catalyst, magnesium hydroxide, and excess magnesium sulfate and/or sulfide, passing the dehydrated slurry of through a filtration system comprising a filtration press to separate the molten polyether polyol phase from the precipitated solid phase, wherein the filtration press is treated with a filter aid that is essentially free of transition metal oxide content, separating the molten polyether polyol phase substantially free of water, residual alkali metal catalyst and transition metal contaminants from the precipitated solid phase and recovering polyether polyol from the separated polyether polyol phase.

    摘要： The present invention relates to an improved, fully-integrated continuous process of enhanced process operability for manufacturing copolyether glycols having enhanced physical properties by polymerization of a reaction mixture comprising tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst and at least one compound containing reactive hydrogen atoms. The copolyether glycols manufactured by the present process have enhanced physical properties of increased alkylene oxide incorporation, average molecular weight and polydispersity, as well as reduced crystallinity, color, oligomeric cyclic ether content, and linear oligomer having an average molecular weight of up to about 400 dalton content.
