ABSTRACT:
A process of separation and purification of a propargyl alcohol which comprises treating a propargyl alcohol represented by Formula (I): ##STR1## wherein each of R.sub.1 and R.sub.2 represents a substituent which is different from each other, and is selected from the group consisting of a C.sub.1 -C.sub.8 alkyl group, a phenyl group; a halophenyl group, a phenyl group having at least one methyl substituent, an aralkyl group and a cycloalkyl group,
which is chemically or optically impure,
with a tertiary diamine represented by Formula (II): ##STR2## wherein each of R.sub.3, R.sub.4, R.sub.5 and R.sub.6 may be the same or different and represents an aralkyl group or an alkyl group having 1 to 6 carbon atoms; and R.sub.3, R.sub.4, R.sub.5 and R.sub.6 may be bonded to each other,
to form a crystalline complex compound of the propargyl alcohol represented by Formula (I) and the tertiary diamine represented by Formula (II), separating and purifying the resulting compound, and treating the resultant compound with an acid to isolate the propargyl alcohol represented by Formula (I).
