  • Process for preparing highly branched polyhydroxybenzoic acid alkoxylates
    Patent number: 8664427
    Abstract: The invention relates to a process for preparing hyperbranched polyhydroxybenzoic acid alkoxylates, comprising the steps of: (a) reacting at least one polyhydroxybenzoic ester with one or more alkylene oxides, optionally in the presence of a basic catalyst, (b) allowing the polyhydroxybenzoic ester alkoxylates formed in step (a) to react with transesterification to form hyperbranched polyhydroxybenzoic acid alkoxylates.
    Type: Grant
    Filed: October 14, 2010
    Date of Patent: March 4, 2014

  • METHOD FOR PRODUCING POLYETHER ALCOHOLS
    Publication number: 20100261870
    Abstract: The invention provides a process for preparing polyether alcohols by adding alkylene oxides onto H-functional starter substances, of which at least one is solid at room temperature in a reaction vessel, by feeding the starting components continuously to the reaction vessel, which comprises preparing a paste from the solid starter substance and feeding this paste continuously to the reaction vessel.
