  • Zinc cluster compounds and their use as catalysts in the reaction of amines with dialkyl carbonates
    Patent number: 9988344
    Abstract: The present invention relates to metallic zinc cluster compounds which are suitable as catalysts in the reaction of amines with dialkyl carbonates to produce carbamates. The invention is also directed towards a method for the alkoxycarbonylation of amines. The cluster compound has a general formula which may be written as [M(O2C—R)2]x.[MO]y.[H2O]z, wherein M is Zn, R is an unsubstituted or substituted aromatic, cycloaliphatic, linear aliphatic, or other organic rest, x is 1, y is ?x is 1, y is ?0.03 to ?26.0 and z is >0.00 to ?17.0.

  • Polyether esters as flame retardants for polyurethane flexible foams
    Publication number: 20050159500
    Abstract: Flexible polyurethane foams that satisfy the requirements of FMVSS 302 are produced by reacting a polyisocyanate with a polyol component that includes: (1) from 90 to 99 parts by weight of a polyether polyol having an OH value of from 20 to 200 mg KOH/g and functionality of from 2 to 4 and (2) from 1 to 10 parts by weight of a polyether ester polyol having an OH value of from 150 to 450 mg KOH/g and a functionality of from 2 to 3 in the presence of a blowing agent, catalyst and stabilizer. The foams thus produced are useful as cushioning for furniture and automotive applications.
