Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
142 words
A process for the preparation of monoacyl polyalkylene polyamines of the formula ##STR6## wherein R 1 is straight or branched chain alkyl of from 7 to 21 carbon atoms or mixtures thereof, n is an integer of from 1 to 3 and X is straight or branched chain alkylene or hydroxyalkylene of from 2 to 6 carbon atoms, comprising reacting a fatty acid ester of the formula ##STR7## wherein R 1 is as above and R 2 is lower alkyl of from 1 to 3 carbon atoms, with a polyalkylene polyamine of the formula H.sub.2 N--(X--NH).sub.n H wherein X and n are as above, in the presence of from about 5 to 40% by weight of the total weight of the reaction mixture of a hydroxylic solvent and at a temperature of from about 20° C. to 80° C. or under pressure.
Claim 2
Dependent Claim
142 words
A process for the preparation of monoacyl polyalkylene polyamines of the formula ##STR6## wherein R 1 is straight or branched chain alkyl of from 7 to 21 carbon atoms or mixtures thereof, n is an integer of from 1 to 3 and X is straight or branched chain alkylene or hydroxyalkylene of from 2 to 6 carbon atoms, comprising reacting a fatty acid ester of the formula ##STR7## wherein R 1 is as above and R 2 is lower alkyl of from 1 to 3 carbon atoms, with a polyalkylene polyamine of the formula H.sub.2 N--(X--NH).sub.n H wherein X and n are as above, in the presence of from about 5 to 40% by weight of the total weight of the reaction mixture of a hydroxylic solvent and at a temperature of from about 20° C. to 80° C. or under pressure.
Claim 3
Dependent Claim
20 words
The process of claim 1 wherein the hydroxylic solvent is selected from the group consisting of methanol, ethanol and isopropanol.
Claim 4
Dependent Claim
11 words

Claim 5
Dependent Claim
25 words
The process of claim 1 wherein the polyalkylene polyamine and fatty acid ester are present in a mole ratio of from about 25:1 to 5:1.
Claim 6
Dependent Claim
25 words
The process of claim 4 wherein the polyalkylene polyamine and fatty acid ester are present in a mole ratio of from about 20:1 to 10:1.
