| titleOfInvention | Quaternary ammonium xanthates |
| abstract | The invention comprises quaternary ammonium xanthates of the formula (NRR1R2R3)+(YO-CSS)-where R and R1 are methyl, R2 is methyl, phenyl or benzyl, or RR1R2 together represent the carbon atoms of a pyridine ring, R3 is a C8-C20 aliphatic hydrocarbon group, an aralkyl group, an esterified carboxyethyl group or (if R=R1=methyl and R2=benzyl) a p-diisobutylphenoxyethoxyethyl group or (if R, R1 and R2 are not methyl and Y is not ethyl or propyl) a phenyl group, and Y is C1-C4 alkyl or alkenyl. These are made by double decomposition between the quaternary halide and alkali metal xanthate up to 70 DEG C., preferably in the presence of a diluent in which the reactants and product are soluble but alkali halide is not; lower alkanols such as isopropanol are suitable. The quaternary xanthate may be extracted with an aromatic hydrocarbon solvent or left in aqueous solution for use. Examples show the preparation of dodecyltrimethylammonium isopropylxanthate, ethylxanthate, allylxanthate and isobutylxanthate (coconut alkyl) - trimethylammonium isopropylxanthate (soya alkyl)-trimethylammonium isopropylxanthate, laurylpyridinium ethylxanthate, propylxanthate, isopropylxanthate, allylxanthate, butylxanthate and isobutylxanthate, cetyldimethylbenzylammonium isopropylxanthate, p - diisobutylphenoxyethoxyethyl - di - methylbenzyl - ammonium isopropylxanthate and methoxycarbonylethyl - dimethyldodecyl - ammonium isopropylxanthate. Other products are mentioned in which R3 is also phenyl, benzyl, octyl, decyl, tetradecyl, octadecyl and octadecenyl and Y may also be methyl.ALSO:Quaternary ammonium xanthates of the formula (NRR1R2R3)+(YO-CSS)- are used as bactericidal, bacteriostatic, fungicidal, herbicidal, algicidal and insecticidal agents as solutions in water, benzene, xylene or other aromatic solvent, as emulsion concentrates, or as dusts mixed with an inert fluent carrier such as talc, kieselguhr, clay or chalk. The liquid compositions may contain an adhesive such as a rubber or synthetic resin latex, fish oil, vegetable oil or heavy mineral oil. In the above formula R and R1 are methyl, R2 is methyl, phenyl or benzyl, or R,R1,R2 together represent the carbon atoms of a pyridine ring, R3 is a C8-C20 aliphatic hydrocarbon group, an aralkyl group, an esterified carboxyethyl group or (if R=R1=methyl and R2=benzyl) a p-diisobutylphenoxyethoxyethyl group, or (if R, R1 and R2 are not methyl and Y is not ethyl or propyl) a phenyl group, and Y is C1-C4 alkyl or alkenyl. Many suitable compounds are mentioned, in which R3 is phenyl, benzyl, octyl, decyl, dodecyl, tetradecyl, cetyl, octadecyl, octadecenyl, mixed alkyl from coconut and soya oil acids or the groups mentioned above, and Y is methyl, ethyl, propyl, isopropyl, butyl, isobutyl or allyl. |
