Abstract

Process for the separation of the steroisomers of substituted vinylcyclopropanecarboxylic acids of general formula (I) (see figure i) where r means alkyl with 1-4 carbon atoms and/or halogen, the position of the substituents on the cyclopropane ring is cis or after each other and the molecules can also be present in an optimally active form, characterized in that the free acid is subjected to a fractional distillation and the different fractions are purified by recrystallization.
