СПОСОБ ПОЛУЧЕНИЯ ДОДЕКАДИЕН-7,10-овой КИСЛОТЫMETHOD OF OBTAINING DODECADIUM-7,10-oVIC ACID
Предложен способ получени додекадиен7 ,10-овой кислоты, заключающийс в том, что 1-галоидбутен-2 конденсируют с октин-7-овой кислотой и полученную додекаен-10-ин-7овую кислоту гидрируют в присутствии палладиевого катализатора, отравленного уксуснокислым свинцом, в додекадиен-7,10-овую кислоту . Полученна додекадиен-7,10-ова кислота вл етс новой, она может быть исиользована в качестве компонента высыхающих и полувысыхающих растительных масел, которые , в свою очередь, наход т применение в различных отрасл х народного хоз йства.A method for producing dodecadien 7, 10-oic acid is proposed. It consists in that 1-halobutene-2 condenses with octin-7-oic acid and the resulting dodecane-10-in-7 acid is hydrogenated in the presence of a palladium catalyst poisoned with acetic acid, in dodecadien -7,10-ovic acid. The resulting dodecadien-7,10-ovic acid is new, it can be used as a component of drying and half-drying vegetable oils, which, in turn, are used in various sectors of the national economy.
