Description

3 Предмет изобретени  Способ выделени  жидкого стереоизомера диокиси метилового эфира линолевой кислоты из смеси двух стереоизомеров, содержащей в 5 качестве второго компонента твердый стереоизомер диокиси метилового эфира линолевой кислоты, путем адсорбционной хроматографии на силикагеле с применением системы раство10 4 рителей, содерл ащей диэтиловый эфир, отличающийс  тем, что, с целью интенсификации процесса и повышени  степени чистоты целевого продукта, адсорбционную хроматографию ведут в колонке при соотношении силинагель: исходна  смесь, равном 100:40-1, и в качестве второго компонента системы ра-створителей примен ют петролейный эфир в количестве , в 1,5 раза превышающем количество диэтилового эфира.3 Subject of the Invention A method for separating liquid stereoisomer of linoleic acid methyl ester from a mixture of two stereoisomers, containing in 5 as a second component a solid stereoisomer of linoleic acid methyl ester, by adsorption chromatography on silica gel using a solvent system containing diethyl ether different from that, in order to intensify the process and increase the purity of the target product, adsorption chromatography is carried out in a column with a ratio of silica gel: and Khodnev mixture of 100: 40-1, and as a second component of the system ra-stvoriteley petroleum ether is used in an amount of 1.5 times the amount of diethyl ether.
