Abstract
A process for producing a phenothiazinium compound comprising the step of: reacting phenothiazine, in the presence of a halogen, with at least one amine selected from the group consisting of: wherein Z is CH2, O, S, SO2, NH, NCH3, NC2H5, NCH2CH2OH or NCOCH3, and R1 and R2 are each independently linear or branched CnH2nY; and replacing the halogen with a non-halide counteranion.

A process for producing a phenothiazinium compound comprising the step of:
- reacting phenothiazine, in the presence of a halogen, with at least one amine selected from the group consisting of:
- wherein Z is CH2, O, S, SO2, NH, NCH3, NC2H5, NCH2CH2OH or NCOCH3, and R1 and R2 are each independently linear or branched CnH2nY, and wherein said phenothiazinium compound has the general formula:
- wherein A and B are each selected from the group consisting of:
- wherein Z is CH2, O, S, SO2, NH, NCH3, NC2H5, NCH2CH2OH or NCOCH3 and R1 and R2 are each independently linear or branched CnH2nY, where n is 1-6, Y is H, F, Br, I, OH, OCH3, OC2H5, OC3H7, CN or OCOCH3, and where X− is a halide counteranion;
- and
- replacing said halide counteranion with a non-halide counteranion.
A process for producing a phenothiazinium compound comprising the step of:
- reacting phenothiazine, in the presence of a bromine, with at least one dialkylamine;
- and
- replacing said bromine with a non-halide counteranion.
