Tertiary amines viz. 3-(diethylamino)-2-hydroxypropyl-2-(4-chlorophenoxy) acetate (6a), 3-(diethylamino)-2-hydroxypropyl-2-(2-chlorophenoxy)acetate (6b), (3-N,N-diethylamino-2-hydroxypropyl)-3-(2-nitrophenyl)prop-2-en-1-oate (11a) and (3-N,N-diethylamino-2-hydroxypropyl)-3-(4-chlorophenyl)prop-2-enoate (11b) were prepared through the formation of glycidyl ester. Primary amine (ethanolamine), secondary amines (diethylamine and piperidine) and the synthesized tertiary amines (6a, 6b, 11a and 11b) were reacted with 2,4-dichloroacetic acid (2,4-D) to get secondary (1a), tertiary (1b and 1c) and quaternary (1d-g) ammonium salts. These salts (1a-g) were tested on rice (Oryza sativa, PR-114) for their biological activity. All the tested compounds are found to possess more plant growth retardant activity than that of 2,4-D.
Manufacture and use of herbicide chlorinated phenoxy formulation

Page/Page column 2, (2008/06/13)
The invention pertains to a method for increasing the activity of chlorinated phenoxy herbicides by specially formulating said herbicides with a combination of solvent and selected surfactants. This method requires the use of alkylated fatty esters and an alkaline buffer. This unique combination of components has been seen to allow lower use rates of chlorinated phenoxy herbicides while also providing a stable formulation.
