Abstract
.Invenţia se referă la un procedeu de preparare a amestecului de izomeri ai zipermetrinei sub formă de produs cristalin stabilizat cu formula:în care atomii de carbon în poziţia 1, 3 şi α sunt atomi chiralici de carbon, iar linia ondulată indică o configuraţie cis- sau trans- în raport cu nucleul ciclopropanic, amestecul final de izomeri din cei 8 izomeri ai zipermetrinei, teoretic posibil, conţinând, cel puţin, 95% sau a perechii de izomeri IR trans S şi IS trans (Ib) sau a amestecului perechii de izomeri IR cis S şi IS cis R (Ia) şi perechii izomerilor (Ib) în raportul (Ia):(Ib)= 55:45-25:75, preparate prin transformarea asimetrică de gradul II în prezenţa unei baze amine şi a unui solvent din amestecul iniţial de izomeri ai zipermetrinei, amestecul conţinând deopotrivă cu perechea de izomeri (Ib) cisizomeri şi alţi transizomeri sau o pereche de izomeri Ia+Ib într-un raport indezirabil.
