Abstract

The recent discovery of the remarkable insecticidal activity of the organic thiocyanates has led to a search for the most economical and satisfactory method of preparation from the most available raw materials. In the use of these compounds as insecticides, a petroleum oil base is practically always used as a carrier, and if a satisfactory method of introducing the thiocyanate group into some constituent of this base could be found, the manufacture of these insecticides could be greatly simplified and cheapened. The occurrence, in the kerosene and gasoline fractions of petroleum of considerable amounts of unsaturated compounds, together with the discovery by Söderback of the addition of thiocyanogen to certain ethylenic compounds, provides a possible method of accomplishing this result. The formation of thiocyanogen at the anode during the electrolysis of alkali thiocyanate solutions was noted by Kerstein and Hoffman.

The purpose of this investigation was to determine whether or not tho free thiocyanogen formed at the anode of an electrolytic cell could be made to add to the unsaturated compounds present in commercial grades of kerosene end gasoline, and if so, the optimum conditions under which it would add, and to determine the extent of that addition and the nature of the products formed.
