Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
70 words
A quaternary ammonium compound having the structural formula ##STR4## wherein R is a lower alkyl group of from 1 to 4 carbon atoms, and X is either a halogen having an atomic weight greater than 30, methosulfate or ethosulfate, the term decyl referring to a mixture of primary branched chain alkyl groups, each of which has 10 carbon atoms and consists of a straight chain having at least two branches.
Claim 2
Dependent Claim
70 words
A quaternary ammonium compound having the structural formula ##STR4## wherein R is a lower alkyl group of from 1 to 4 carbon atoms, and X is either a halogen having an atomic weight greater than 30, methosulfate or ethosulfate, the term decyl referring to a mixture of primary branched chain alkyl groups, each of which has 10 carbon atoms and consists of a straight chain having at least two branches.
