Abstract
Compounds of the structure ##STR1## wherein X is --F or Cl and each R is independently --H, --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3, --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 or M where M is an alkali metal, an alkaline earth metal, ammonium or a quaternary ammonium are disclosed. The above compounds are prepared by treating a compound of the structure ##STR2## where each R.sup.1 is independently --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3 or --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 ; or ##STR3## with a strong protic acid, followed, as desired, by base hydrolysis to form carboxylate salts (R.dbd.M).
Claims8
Compounds of the structure ##STR22## wherein X is --F or --Cl and each R is independently --H, --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3, --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 or M where M is an alkali metal, an alkaline earth metal, ammonium or quaternary ammonium.
A process of preparing compounds of the structure ##STR23## wherein X is --F or --Cl and each R is independently --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3 or --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 by treating a compound of the structure ##STR24## wherein each R.sup.1 is independently --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 CH.sub.2 CH.sub.3, or --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.3 with a strong protic acid.
