摘要： PROBLEM TO BE SOLVED: To provide a process for the production of a polyether polyol having a low unsaturation degree from an arbitrary alcohol source.
SOLUTION: The process for the production of the polyether polyol comprises adding to a boron-containing starter compound from about 0.75 equivalent to about 7 equivalents of an acid per equivalent of boron, and polyoxyalkylating the boron-containing starter compound with an alkylene oxide in the presence of a double metal cyanide (DMC) catalyst.

摘要： PROBLEM TO BE SOLVED: To provide an improved process for producing a water-miscible metal-working fluid with aerosol inhalation toxicity reduced than that of a conventional product.
SOLUTION: The process for producing the water-miscible metal-working fluid involves combining 90-5 wt.%, based on the weight of the fluid, of water and one or more additives chosen from plasticizers and the like with 10-95 wt.%, based on the weight of the fluid, of a polyether polyol produced by mixing an active hydrogen compound with a double metal cyanide (DMC) catalyst in a reactor vessel, charging to the reactor vessel a mixture containing two or more kinds alkylene oxides to activate the catalyst, and continuously feeding one or more kinds alkylene oxides to produce the polyether polyol, wherein a 1% solution in water of the polyether polyol has a cloud point of from higher than 32°C. to lower than 53°C, the polyol has a number average equivalent weight of from greater than 1,600 Da to 10,000 Da, and a four-hour aerosol inhalation exposure to the polyether polyol has a LC
50 of greater than 5 mg/L.
