Abstract
The invention comprises mixed sulphite diesters of an acyclic alkynyl alcohol and a saturated aliphatic alcohol or phenol, particularly diesters of the formula: <FORM:0968058/C1/1> wherein R is an alkyl, aralkyl, cyanoalkyl, haloalkyl, carbalkoxyalkyl aryl, alkaryl or haloaryl radical and R1 is an acyclic-alkynyl radical. The esters are prepared from the chlorosulphinate of the alcohol or phenol, by treatment in a solvent, e.g. benzene, xylene or solvent naphtha, with the alkynyl alcohol in the presence of an HCl acceptor, e.g. pyridine, dimethylaniline or trimethylamine, at between -10 DEG and 50 DEG C. The chlorosulphinate is prepared by treatment of alcohol or phenol with thionyl chloride at between -5 DEG and 30 DEG C. These compounds may be used as insecticides. (see Division A5).ALSO:Insecticidal compositions contain as the active ingredients mixed sulphite esters of an acyclic alkynyl alcohol and a saturated aliphatic alcohol or phenol, particularly diesters of the general formula <FORM:0968058/A5-A6/1> wherein R is an alkyl, cyanoalkyl haloalkyl, carbalkoxy alkyl, aryl, aralkyl, alkaryl or haloaryl radical and R1 is an acyclic-alkynyl radical (see Division C2). The chemicals may be applied as dusts mixed with powdered solid carriers, for example mica, talc, pyrophyllite and clays; as liquids or sprays when dissolved in a solvent, for example acetone, benzene or kerosene, or as aerosol sprays when dissolved directly in an aerosol carrier. They are preferably used as aqueous emulsions containing an anionic, non-ionic or cationic surface active dispersing agent or as aqueous suspensions containing solid powder carriers and dispersing agents. Examples describe the use of proparyl tridecyl sulphite in the control of mosquito larvae and propargyl tridecyl sulphite and 2-(3-butynyl) hexadecyl sulphite in the control of mites.
