Abstract

The invention relates to compounds of the general formula <FORM:1049148/C2/1> in which Ar is an aromatic radical which may have one or more chlorine atoms or alkyl radicals as substituents, R1 is a methyl radical or a hydroxy alkyl radical and R2 is a hydroxy alkyl radical or a phenyl radical. Compounds claimed per se are those in which R2 is -CH2CH2OH and R1 is methyl and R is phenyl, metachloro-, 2,4-dichloro-, paramethyl-2,4-dimethyl-, 2-methyl-4-chloro-, and p-isobutyl phenyl and naphthyl; R1 and R2 are C3H6OH and R phenyl, parachloro-, m-methyl-phenyl and naphthyl; R1 is methyl and R2 is phenyl and R is phenyl, p-chloro-, 2,4-dichloro-, 2,4,5-trichloro-, 2,3,4,5,6-pentachlorophenyl. The compounds are prepared by reacting an ester of an aromatic hydroxyl compound of an alpha, beta-ethylenically unsaturated sulphonic acid with a secondary hydroxyalkylamine or aniline and the product quaternized by means of an alkylating agent.ALSO:Fungicidal compositions comprises active ingredient compounds of the general formula <FORM:1049148/A5-A6/1> in which Ar is an aromatic radical with one or more chlorine atoms or alkyl radicals as substituents, R1 is a methyl or hydroxy alkyl radical and R2 is a hydroxy alkyl or phenyl radical, together with conventional diluents or carriers e.g. water, organic liquids, dispersing agents, wetting agents, solid inert substances. Other active substances e.g. acaricides, insecticides, ovicides, herbicides, fungicides or bactericides may also be included.
