Abstract

Abstract Novel alkoxylated tertiary amine compounds of the formula are prepared by reacting an oxyalkylated alcohol with a secondary amine in the presence of a reductive amination catalyst at above ambient temperature and superatmospheric pressure. The amine compounds are useful as corrosion inhibitors, full additives, curing agents for epoxy resins and as biocides.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 263 words
, 1. A process for the preparation of an alkoxylated tertiary amine having the formula or a mixture of such amines which comprises reacting an oxy- alkated alcohol of the formula or a mixture of such alcohols, with a secondary amine of the formula HNR 3 R 4 at a temperature in the range of from about 150°C to 325°C and a pressure of from about 50 psig to 3000 psig in the presence of from.0.5 to 20 weight percent of an amination catalyst based on the total reaction mixture and wherein R is a straight or branched chain alkyl group having from 1 to 11 carbon atoms, a cyclic alkyl group having from 5 to 10 carbon atoms, an aryl group having up to 12 carbon atoms, or an aralkyl or alkaryl group having up to 18 carbon atoms, R 1 is a single unit or a series of units of the formula: wherein in each unit R 5 is independently selected from the group consisting of hydrogen and a straight or branched chain alkyl group having from 1 to 12 carbon atoms and x is an integer of from 0 to 40, R 2 is hydrogen or a straight or branched chain alkyl group having from 1 to 12 carbon atoms, R 3 and R 4 are each independently selected from the group consisting of straight and branched chain alkyl groups having from 1 to 12 carbon atoms cyclic alkyl groups having from 5 to 10 carbon atoms, 1 to 4 carbon atom alkyl substituted or unsubstituted benzyl groups and allyl.
Claim 2
Dependent Claim 43 words

Claim 3
Dependent Claim 18 words
A process according to claim 2 but wherein R 1 is a group, a group or a group.
Claim 4
Dependent Claim 26 words
A process according to any one of claims 1 to 3 wherein the amination catalyst is a mixture of Cu0 and Cr 2 0 3 .
Claim 5
Dependent Claim 24 words
A process according to any one of claims 1 to 3 wherein the amination catalyst is copper and chromium supported on magnesium aluminate spinel.
Claim 6
Dependent Claim 21 words
A process according to any one of claims 1 to 3 wherein the amination catalyst is ruthenium supported on activated carbon.
Claim 7
Dependent Claim 27 words
A process according to any one of claims 1 to 6 wherein the amination catalyst is employed in an amount of from 2.5 to 10 weight percent.
Claim 8
Dependent Claim 23 words
A process according to any one of claims 1 to 7 wherein the temperature is in the range of from 175°C to 275°C.
Claim 9
Dependent Claim 21 words
