Abstract
The process comprises treatment of N-(3-trifluoromethylphenyl)- anthranylate of 2-(2-hydroxyethoxy)-ethyl, through molecular distillation after the prepn. reaction. The crude product is degassed beforehand, at 5x10 power -2 mbar and at a water cooling jacket temp. of ca.120 deg.C. Pref. the distillation is carried out at below 10 power -3 mbar and at a water jacket temp. of ca. 180 degs.C.
