Abstract/OtherAbstract:
|
A new esterification procedure was developed to form 2-chloroethyl esters for 10 common herbicidal acids, using dicyclohexyl carbodiimide and 2-chloroethanol. This reagent was found to be more desirable than the commonly used boron trichloride/2-chloroethanol reagent. Maximum esterification was given for picloram at a lower reaction temperature with a shorter reaction time. Also, maximum esterification of dicamba and 2,3,6-TBA was achieved. The boron trichloride/2-chlorethanol gave poor or little esterification with these 2 acids under the various conditions investigated. The effect of solvents on esterification with the 2 reagents was also explored. |
