Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
49 words
Quaternaries of products produced by reacting about 1 mole of an unsaturated nitrile with about 3 moles of an alkanolamine so that one mole reacts with the unsaturated group to form an N-alkanol group and the other 2 moles react with the nitrile group to form an hydroxyalkylaminoalkylamide group.
Claim 2
Dependent Claim
49 words
Quaternaries of products produced by reacting about 1 mole of an unsaturated nitrile with about 3 moles of an alkanolamine so that one mole reacts with the unsaturated group to form an N-alkanol group and the other 2 moles react with the nitrile group to form an hydroxyalkylaminoalkylamide group.
Claim 3
Dependent Claim
17 words
Quaternaries of products of claim 1 where the unsaturated nitrile is an acrylo- or a substituted acrylo-nitrile.
Claim 4
Dependent Claim
12 words
Quaternaries of products of claim 2 where the unsaturated nitrile is acrylonitrile.
Claim 5
Dependent Claim
13 words
Quaternaries of products of claim 1 where the unsaturated nitrile is an arylnitrile.
Claim 6
Dependent Claim
11 words
Quaternaries of products of claim 4 where the arylnitrile is φCH═CH-CN.
Claim 7
Dependent Claim
17 words
The quaternaries of claim 2 wherein R' is aryl, R" is hydrogen and R 2 is methyl.
Claim 8
Dependent Claim
9 words
The quaternaries of claim 2 of the formula ##STR23##
Claim 9
Dependent Claim
9 words
The quaternaries of claim 2 of the formula ##STR24##
Claim 10
Dependent Claim
31 words
Quaternaries of compounds of the formula ##STR25## where R' and R" are hydrogen, alkyl, aryl, cycloalkyl, alkaryl or aralkyl and R 2 is hydrogen, alkyl, cycloalkyl, aryl, aralkyl, hydroxyalkyl or alkenyl.
Claim 11
Dependent Claim
31 words
Quaternaries of compounds of the formula ##STR25## where R' and R" are hydrogen, alkyl, aryl, cycloalkyl, alkaryl or aralkyl and R 2 is hydrogen, alkyl, cycloalkyl, aryl, aralkyl, hydroxyalkyl or alkenyl.
