Abstract

Esters of 4,6-dinitro-2-sec.-butylphenol of the general formula <FORM:0918954/IV (b)/1> in which R1 and R2 represent the same or different alkyl groups containing 1 to 4 carbon atoms, particularly the b -methyl-b -n-propylacrylic acid ester of 4,6-dinitro-2-sec.-butylphenol, are made by reacting 4,6-dinitro-2-sec.-butylphenol with a b ,b -dialkylacrylic acid-anhydride or acid-halide. Another alternative is to react a 4,6-dinitro-2-sec.-butylphenolate with a b ,b -dialkylacrylic acid-halide. The reaction may be effected, e.g., by dissolving equal molar quantities of 4,6-dinitro-2-sec.-butylphenol and the acid-halide in benzene or carbon tetrachloride, and by adding pyridine or dimethyl-aniline at such a rate that the boiling temperature is reached. The mixture is then boiled under reflux, cooled and washed with dilute hydrochloric acid. After all the amine has been removed, the product is washed with sodium carbonate solution, and finally it is washed with water. The esters have use in pesticidal preparations (Group VI).ALSO:Pesticidal compositions comprise esters of 4,6 - dinitro - 2 - sec. - butylphenol of the general formula <FORM:0918954/VI/1> (in which R1 and R2 represent the same or different alkyl groups containing 1 to 4 carbon atoms) in admixture with a solid or liquid diluent. In examples, the composition comprises 25% of the b -methyl-n-propylacrylic acid ester of 2,4-dinitro-2-sec.-butylphenol, 64% of amorphous silicic acid, 10% of the calcium salt of lignin sulphonic acid, and 1% of sodium methyltauride oleate; and is used, as an aqueous liquor of 0.05% strength, to spray bean plants infested with spider mites. or the b - methyl - b - n - propyl acrylic acid ester of 4 : 6 dinitro - 2 - sec. - butyl phenol, butanol, xylol and an alkyl phenol polyglycol ether as an emulsifiable concentrate.
