Abstract
The invention comprises 3,6-dichloro-2-picolinic acid derivatives of the formula <FORM:1003937/C2/1> in which Y is a carboxylic acid, cyano, carboxylic acid salt, carboxylic acid hydrazide, carboxylic acid ester, or carboxylic acid amide group. 3,6-Dichloro-2-picolinic acid is prepared by heating 3,6-dichloro-2-(trichloromethyl) pyridine in the presence of a mineral acid. Salts and esters are obtained by treating the acid with a base or hydroxy compound. Amides and hydrazides are obtained by treating the ester with an appropriate nitrogen base. The cyano compound is obtained by heating the amide with phosphorus pentoxide. The 3,6-dichloro-2-(trichloromethyl) pyridine is obtained by photochlorinating 3-chloro-2-(trichloromethyl) pyridine at 120 DEG to 130 DEG C.ALSO:Herbicidal compositions contain as active ingredient, a 3, 6-dichloro-2-picolinic acid compound of the formula:- <FORM:1003937/A5-A6/1> in which Y is a carboxylic acid, carboxylic acid salt, ester, amide or hydrazide, or a cyano group together with a carrier. The compositions may also contain other plant growth control agents, hormones, contact herbicides, pesticides and/or modifying agents. In an example the compounds are used in aqueous compositions.
