Patent ID: 7977284

Claim:
A method for producing non-estrogenic phenol and alkylphenol compounds of the following structure or Where: R and R 1 are each separately and independently=H, C1-C24 linear or branched alkyl or C2-C24 linear or branched alkylene, x=1, y=1-30, z=0-30, A=H, SO3A, SO 4 A, COOA, PO4, M=H, Na, K, NH4, Amine, Ca, Mg, Q=SO 3 or C1-C30 alkyl sulfonyl, and, a=0-2, n=2 or more, by reacting the phenol or alkylphenol precursor of the structure I where R and R 1 are each separately and independently=H, C1-C24 linear or branched alkyl or C2-C24 linear or branched alkylene, with propylene carbonate to form the one mole propoxylated adduct followed by further ethoxylation and/or propoxylation and subsequent conversion to the desired derivative.
