    摘要： The present invention provides a process for the production of a polyether involving establishing oxyalkylation conditions in an oxyalkylation reactor in the presence of from about 5 ppm to about 1,000 ppm, based on the final polyether weight, of a double metal cyanide (DMC) catalyst, continuously introducing into the reactor at least one alkylene oxide and a low molecular weight starter having a number average molecular weight of less than about 300 Daltons (Da) containing from about 200 ppm to about 5,000 ppm water and acidified with from about 10 ppm to about 2,000 ppm of at least one of an inorganic protic mineral acid and an organic acid, and recovering a polyether product having a number average molecular weight of from about 200 Da to about 4,000 Da, wherein the ppm (parts per million) of water and acid are based on the weight of the low molecular weight starter. The inventive process may allow for the use of low molecular weight starters containing higher levels of water at lower DMC catalyst levels than current processes.

    摘要： Polyether polyols with an OH number of from 15 to 120 mg of KOH/g are produced by (i) introducing a mixture of DMC catalyst and a poly(oxyalkylene)polyol or a mixture of DMC catalyst and a polyether polyol (“heel”) obtainable by the process according to the invention is initially into a reactor and (ii) continuously introducing one (or more) low molecular weight starter compound(s) with a (mixed) hydroxyl functionality of from 2.2 to 6.0 and a mixture composed of a) 73 to 80 parts by weight (per 100 parts by weight of a) plus b)) of ethylene oxide and b) 27 to 20 parts by weight (per 100 parts by weight of a) plus b)) of at least one substituted alkylene oxide corresponding to a specified formula into the mixture from step (i). These polyether polyols are particularly useful for the production of flexible polyurethane foams.

    摘要： The present invention provides a process for the polyoxyalkylation of a starter involving establishing oxyalkylation conditions in an oxyalkylation reactor in the presence of a double metal cyanide (DMC) catalyst, continuously introducing into the reactor at least one alkylene oxide and an acidified, ultra-low water content starter, in which the starter contains greater than about 100 ppm and less than or equal to about 500 ppm water, based on the weight of the starter, and recovering an oxyalkylated low molecular weight starter polyether product. The inventive process allows the production of short chain polyether polyols which have hydroxyl numbers of from greater than 250 up to about 500, from hygroscopic initiators, such as glycerin, without DMC catalyst deactivation.

    摘要： Oligomeric polyoxyalkylene polyethers are prepared by oxyalkylating a low molecular weight hydroxyl-functional starter molecule with one or more alkylene oxides in the presence of a solid, heterogeneous magnesium oxide catalyst. The catalyst is readily and rapidly removed by simple filtration to yield a polyether with minimal metal ion content suitable for use directly or as a starter molecule for further double metal cyanide complex catalyzed oxyalkylation.
