Abstract

Dodecyl thiocyano methyl ether is prepared by converting dodecyl alcohol with formaldehyde and hydrochloric acid into dodecyl chlormethyl ether, and boiling this with thiocyanates. Decyl and dodecyl amides of thiocyano acetic acid are prepared by reacting thiocyano acetic acid with decyl or dodecyl amides. Reference has been directed by the Comptroller to Specification 361,900.ALSO:Insecticides, bactericides, and fungicides, particularly for treating plants contain, in admixture with wetting and emulsifying agents and solvents, an active compound of the general formula R-X-Y-SCN, in which R represents a substituted or unsubstituted aliphatic or cycloaliphatic radical of 10 or of 12 carbon atoms, Y a low molecular alkylene radical or an arylene radical, and X represents the atoms or groups O, S, Se, OCO, OCS, NHCO, NH, NR1, SO2, NH SO2 or SO2 NH, R1 being a hydrocarbon radical. Active compounds specified are decyl and dodecyl esters of thiocyanoacetic acid, dodecyl thiocyano methyl ether, thiocyanothio acetic acid decyl ester and the decyl amide of thiocyano acetic acid. Emulsifying and other additional substances specified are soap, tetrahydro naphthalene, methyl cyclohexanol, turkey red oil, and paste of the sodium salt of the acid octyl and decyl sulphuric acid esters containing fatty alcohol, and the acid sulphuric acid ester of ricinoleic acid octyl ester. Dodecyl thiocyano methyl ether may be prepared by converting dodecyl alcohol with formaldehyde and hydrochloric acid into dodecyl chlormethyl ether and boiling this with thiocyanates; and the decyl and dodecyl amides of thiocyano acetic acid may be prepared by reacting thiocyano acetic acid with decyl or dodecyl amines. The Specification as open to inspection under Sect. 91 relates also to compounds in which R in the general formula is an aliphatic or cyclo-aliphatic radical of at least 6 carbon atoms; specifies additional active substances, viz.-g - thiocyano - b - oxy - propyl - n - octyl ether, thiocyano propionic acid octyl ester, thiocyano phenyl octyl ether, thiocyano salicylic acid octyl ester, p-thiocyanobenzoic acid octyl ester and thiocyano propionic acid ester of 1.8 chloroctanol; and additional emulsifying and other agents, viz.: sodium salt of the acid sulphuric acid ester of mono-octyl glycerin ether, "spirit," and ammonium salts of acid sulphuric acid esters of an alcohol mixture of the aliphatic straight chain alcohols with 6 to 10 carbon atoms with or without small quantities of lower alcohols, such as ethyl alcohol. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 361,900.
