Abstract

Invenţia se referă la un procedeu de preparare a unor amestecuri de izomeri ai cipermetrinei cu formula Iîn care atomii de carbon, marcaţi prin 1, 3 şi α, se referă la atomii chiralici de carbon, iar linia ondulată indică configuraţia cis- sau trans relativ de inelul ciclopropanic, care conţin din cei 8 izomeri teoretic posibili ai cipermetrinei, cel puţin, 95% cuplu de izomeri 1RtransS şi 1StransR (Ib) sau numai amestecul de cupluri de izomeri 1RcisS şi 1ScisR (Ia) şi (Ib) în raport (Ia): (Ib) = 55:45-25:75, prin transformarea asimetrică de gradul 2, în prezenţa unei amine terţiare şi a unui solvent protonic de la 0°C până la +25°C din amestecul iniţial de izomeri ai cipermetrinei de puritate minimă 90 % masă, care conţine şi alţi izomeri cis şi trans, ce urmează după cuplul de izomeri (Ib), sau cuplul de izomeri Ia+Ib într-un raport nedorit. Procesul decurge continuu în câteva reactoare, amplasate consecutiv. La capătul liniei de reactoare se formează cristale, care opţional se separă din suspensia de cristale.
