  • Process for preparing alkoxylation catalysts and alkoxylation process
    Patent number: 5627121
    Abstract: A process for preparing an alkoxylation catalyst suitable for alkoxylating compounds such as active hydrogen-containing compounds wherein an alkoxylated alcohol mixture, a calcium-containing compound that is at least partially dispersible in the alkoxylated alcohol mixture, and a carboxylic acid are mixed together to produce a calcium-containing composition having titratable alkalinity, the composition being obtained under conditions to prevent loss of water, the composition being at least partially neutralized with an inorganic acid under conditions to prevent loss of water to produce a partially neutralized calcium-containing catalyst.

  • Process for clarifying alkoxylated alcohols
    Patent number: 5352842
    Abstract: A process for clarifying an alkoxylated product mixture produced using a calcium-based catalyst wherein the product mixture is heated to a temperature of from about 80.degree. C. to about 175.degree. C. to produce a filtration feed, the filtration feed being passed through a filter medium comprising material possessing polar groups to produce a clarified filtrate, the filtration feed being passed through the filter medium within about 5 days of being prepared, the filtration feed being passed through the filter medium until the desired degree of clarification is obtained, the temperature of the clarified filtrate being less than about 30.degree. C. but above the pour point of the clarified filtrate.
