| description | The invention relates to the process for preparation of cypermetrine isomers mixtures of formula Iwherein 1,3, and α-marked carbon atoms refer to chiralic carbon atom, and waved line indicates to cis or trans configuration relative to cyclopropane nucleus, which contains at least 95% of isomer pairs: IR trans S and IS trans R (Ib) or only IR cis S and IS cis R (Ia) mixture and the (Ib) isomer pair in the ratio of (Ia):(Ib)=55:45 - 25:75, obtained by type 2 asimmetric transformations, in the pressence of an amine base and protonic solvent between O°C and +25°C from the starting cypermetrine isomers mixture, having at least 90% wt % purity, containing and other cis or trans isomers, following after (Ib) pair of isomers or Ia+Ib pairs of isomers in undesired ratio.The process is carried out continuously in several conse cutive reactors. The cristals are formed at the end of reactors chain, which optional are separated from crystalls suspension.
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.
Изобретение относится к способу получения таких смесей изомеров циперметрина с формулойгде углеродные атомы 1, 3 и a относятся к хиральному атому углерода, а волнистая линия указывает на цис- или транс- пространственную конфигурацию, относящуюся к циклопропановому кольцу, которые содержат из 8 теоретически возможных изомеров циперметрина, по крайней мере, 95 вес.% пары изомеров IR транс S и IS транс R (Ib) или только смесь IR цис S и IS цис R(Ia) и пару изомеров (Ib) с соотношением Ia:Ib=55:45-25:75 путем асим |
