Abstract:
A process for the preparation of an MgCl.sub.2.pROH.qH.sub.2 O adduct, where R is a C.sub.1 -C.sub.10 alkyl, 1.ltoreq.p.ltoreq.6, and 0.ltoreq.q.ltoreq.1, comprising:(a) forming a mixture by dispersing magnesium dichloride in an inert liquid immiscible with and chemically inert to the adduct when the adduct is in molten form, the mixture being at a temperature equal to or higher than the melting point of the adduct or being heated to such a temperature;(b) adding alcohol ROH, as defined above, in vapour phases maintaining the temperature at values such that the adduct is melted;(c) emulsifying the adduct in a liquid medium which is immiscible with and chemically inert to the adduct;(d) contacting the adduct with an inert cooling liquid.
