Abstract
PURPOSE: To obtain the titled compound useful as a raw material for the production of perfumes or flavors, in high yield and purity, by the successive reaction of a rectification residue of 1,3-butadiene containing a specific amount or less for 1,3- butadiene, with metallic Li and ethylene oxide.
CONSTITUTION: 1,2-Butadine in a rectification residue of 1,3-butadiene containing 4W0wt% the 1,3-butadiene, is reacted with metallic lithium in an organic ether solvent, at 30W60°C, for 2W8hr, and then butynyl lithium in the resultant mixture is reacted with ethylene oxide at 25W65°C, for 3W9hr, to give 3-hexyn-1-ol of purity as high as 97wt% or more.
EFFECT: All the stages are remarkably simplified with easily designed continuous reactors. Recovery the reaction medium and treatment of an inert gas, e.g. butene, may be facilitated.
