US Patent:

41773357, Dec 4, 1979

Filed:

Apr 14, 1978

Appl. No.:

5/896496

Inventors:

Arthur L. Austin - Southgate MI
William W. Levis - Wyandotte MI
Louis C. Pizzini - Trenton MI
Robert J. Hartman - Southgate MI

Assignee:

BASF Wyandotte Corporation - Wyandotte MI

International Classification:

C08G 1814

US Classification:

521171

Abstract:

An oxyalkylated product useful for making polyurethane foams is prepared by reacting an alkylene oxide with a heated mixture of a phenol and a non-phenolic active hydrogen compound, at least one of which can be halogenated, in the presence of a catalyst complex of a phenol and an iron or aluminum substance. The mixture can also include a neutral phosphorus compound and/or acid anhydrides to enhance flame retardant properties. Optionally, also, the oxyalkylation reaction can be terminated by adding a tri (lower alkyl) amine and alkylene oxide to react with residual phenolic hydrogen in the mixture.

Appl. No.:

5/753650

Inventors:

Arthur Lawrence Austin - Southgate MI
William Walter Levis - Wyandotte MI

Assignee:

BASF Wyandotte Corporation - Wyandotte MI

International Classification:

C07C 4102

US Classification:

260613B

Abstract:

An oxyalkylated, halogenated product useful in making polyurethane foams is prepared by reacting an epoxide compound with a halogenated aromatic hydroxyl-containing compound (phenol) which is either a monohydroxy or polyhydroxy compound. Said aromatic hydroxyl compound has a hydroxy group attached directly to the aromatic nucleus. By the process of the invention, hydroxyalkylation occurs in the presence of a catalyst selectively active in the predominant oxyalkylation of aromatic hydroxyl groups, said catalyst selected from the group consisting of zinc, magnesium and a zinc or magnesium salt as defined. The reaction mixture can include an aliphatic hydroxyl-containing compound, a neutral phosphorus compound, and aliphatic or aromatic anhydrides or mixtures thereof to enhance the flame-retardant properties of the oxyalkylated product.
