Abstract

Przedmiotem zgłoszenia jest sposób wydzielania z mieszaniny poreakcyjnej 4-chloro-2-metylofenoksyoctanów n-bromoalkilowych techniką chromatografii typu Flash. W sposobie tym mieszaninę proreakcyjną z procesu syntezy n-bromoalkilowych estrów kwasu 4-chloro-2-fenoksyoctowego o wzorze ogólnym 1, gdzie R oznacza podstawnik alkilowy zawierający od czterech do dwunastu atomów węgla poddaje się rozdziałowi z użyciem kolumny chromatograficznej o regulowanym przepływie, wypełnionej fazą stałą w postaci żelu krzemionkowego 60 o wielkości ziarna 70 - 230 mesh, zabezpieczoną wacikiem i pokrytej warstwą piasku, przy wykorzystaniu jako eluentu roztworu octanu etylu w heksanie o stężeniu od 10% do 30%, przy czym rozdział przeprowadza się w nadciśnieniu 0,4 bar względem ciśnienia atmosferycznego, przy przepływie cieczy ok. 5 cm/min.
