Patent ID: 10772323

Abstract:
An emulsifiable concentrate comprising a benzoic acid herbicide in acid form dissolved in an amide solvent and an amide solvent and an amine emulsion stabiliser. Preferably: •the benzoic acid herbicide is selected from TBA, chloramben and dicamba acid, •the amine is of the formula (I) NR1R2R3 where wherein R1, R2 and R3 are independently selected from the group selected from hydrogen; C1 to C10 alkyl; C5 or C6 cycloaliphatic optionally substituted with from one to four C1 to C4 alkyl groups and/or an amino-C1 to C4 alkyl group; C1 to C10 alkyl substituted with a substituent selected from the group consisting of hydroxyl, C1 to C10 alkoxy, amino, (C1 to C5 alkyl)amino and di-(C1 to C6 alkyl)amino; and the group wherein two of R1, R2 and R3 together form a ring of 5 or 6 constituent ring members selected from methylene, —O—, —N(H)— and —N(C1 to C6-alkyl) and the other of R1, R2 and R3 is selected from hydrogen, C1 to C5 alkyl and C1 to C5 alkyl substituted with a substituent selected from the group consisting of hydroxyl, C1 to C5 alkoxy, amino and (C1 to C5 alkyl)amino; and wherein at least one of R1, R2 and R3 is other than hydrogen, and •the amide solvents are of the formula (II) R4—CON—R5R6 where R is selected from the group consisting of hydrogen and C1 to C17 hydrocarbyl, and R5 and R6 are is selected from the group consisting of C1 to C15 hydrocarbyl and may together from a ring incorporating the nitrogen of the amide comprising 4 or 5 methylene groups.
