  • Patent number: 10358404
    Abstract: This invention relates to an improved continuous process for the production of low molecular weight polyoxyalkylene polyether polyols. These polyoxyalkylene polyether polyols have a hydroxyl content of from about 3.4 to about 12.1% by weight, and may also be characterized as having an OH number of from about 112 to about 400. The process comprises establishing oxyalkylation conditions in a continuous reactor in the presence of a DMC catalyst; continuously introducing alkylene oxide and a low molecular weight starter into the continuous reactor; recovering a partially oxyalkylated polyether polyol from the reactor; and allowing the recovered partially oxyalkylated polyether polyol to further reactor until the unreacted alkylene oxide content of the mixture is reduced to 0.001% or less by weight.

  • Patent number: 10323212
    Abstract: Polyols are produced by an alkoxylation process in which a vegetable oil containing hydroxyl functional groups is combined with a DMC catalyst to form a mixture, the DMC catalyst is then activated by adding ethylene oxide and/or propylene oxide to the vegetable oil/catalyst mixture, and ethylene oxide and propylene oxide are added to the mixture containing activated DMC catalyst in amounts such that the total of percentage of ethylene oxide in the polyol plus percentage of primary hydroxyl groups in the polyol produced is from 50 to 77% and the percentage of primary hydroxyl groups is at least 30% but less than 50%. These polyols are useful for the production of molded polyurethane foams, particularly, hot-cure molded polyurethane foams.

  • Patent number: 9994506
    Abstract: A process for transitioning a reactor from base-catalyzed polyol production to double metal cyanide (DMC)-catalyzed polyol production is described. The process includes discharging a base-catalyzed and un-neutralized product mixture from a reactor, and adding an acidified polyether polyol starter and DMC catalyst mixture to the reactor. A DMC-catalyzed polyol production reaction can then be conducted in the reactor without intermediate washing or rinsing of the reactor, and without catalyst deactivation from base or alkaline hold-up.

  • Patent number: 9035105
    Abstract: A polyether polyol based on renewable materials is obtained by the in situ production of a polyether from a hydroxyl group-containing vegetable oil, at least one alkylene oxide and a low molecular weight polyol having at least 2 hydroxyl groups. The polyol is produced by introducing the hydroxyl group-containing vegetable oil, a catalyst and an alkylene oxide to a reactor and initiating the alkoxylation reaction. After the alkoxylation reaction has begun but before the reaction has been 20% completed, the low molecular weight polyol having at least 2 hydroxyl groups is continuously introduced into the reactor. After the in situ made polyether polyol product having the desired molecular weight has been formed, the in situ made polyether polyol is removed from the reactor. These polyether polyols are particularly suitable for the production of flexible polyurethane foams.
