Crystalline complex compounds of propargyl alcohols and tertiary diamines, and process of separation and purification of propargyl alcohols using the same

摘要

Disclosed are a crystalline complex compound of a propargyl alcohol represented by Formula (I): wherein each of R₁ and R₂ represents a substituent which is different from each otherand a tertiary diamine represented by Formula (II): wherein A represents a group having two carbon atoms as a chain member which may be branched; each of R₃, R₄ R₅ and R₆ may be the same or different and represents an aralkyl group or an alkyl group having l to 6 carbon atoms; and A, R₃, R₄, R₅ and R₆ may be bonded to each other,and a process of separation and purification of the propargyl alcohol using the crystalline complex compound described above.
