Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A process for inhibiting the growth of microorganisms in aqueous systems which comprises adding to said systems a microbiocidal amount of a quaternary of a tertiary amino-substituted thiazine having the formula selected from the group consisting of ##STR50## where Z is SO or SO 2 , A is alkylene having 2 to 10 carbon atoms, R' is alkyl or hydroxyalkyl, R" is alkyl, alkenyl or alkynyl, ##STR51## represents a cyclic diamine group and X is an anion selected from the group consisting of chloride, iodide, bromide, sulfate, sulfonate and carboxylate.
Claim 2
Dependent Claim
90 words
A process for inhibiting the growth of microorganisms in aqueous systems which comprises adding to said systems a microbiocidal amount of a quaternary of a tertiary amino-substituted thiazine having the formula selected from the group consisting of ##STR50## where Z is SO or SO 2 , A is alkylene having 2 to 10 carbon atoms, R' is alkyl or hydroxyalkyl, R" is alkyl, alkenyl or alkynyl, ##STR51## represents a cyclic diamine group and X is an anion selected from the group consisting of chloride, iodide, bromide, sulfate, sulfonate and carboxylate.
Claim 3
Dependent Claim
57 words
The process of claim 1 where the quaternary has the formula ##STR52## where Z is SO or SO 2 , A is alkylene having 2 to 10 carbon atoms, R' is alkyl or hydroxyalkyl, R" is alkyl, alkenyl or alkynyl and X is an anion from the group consisting of chloride, bromide, iodide, sulfate, sulfonate and carboxylate.
