Abstract
Procedure for the polymerization of vinyl chloride suspension in aqueous mixture and with a suspending or dispersing agent in the presence of a polymerization catalyst, and in a polymerization vessel, provided with a condenser, which communicates with the gas phase of the vessel for removing polymerization heat by the latent heat of the monomer, characterized by the improvement that comprises the steps of stirring the aqueous mixture, to produce a layer of suspended droplets of vinyl chloride, then adding the catalyst to said layer to start the polymerization reaction, said addition being made only when bubbling, caused by agitation, ceases and substantially stable droplets result, whereby condenser blockage by deposition of polymer scale is reduced. A process for preparing 2-piperidylcarbinols comprising catalytically hydrogenating a compound having one of the formulas: ** (See formula) ** where R is straight or branched chain lower alcohol having 1 to 4 carbon atoms, phenyl, tolyl, chlorophenyl, methoxyphenyl or hydroxyphenyl and R1'is straight, branched or branched lower alcohol having 1 to 5 atoms carbon, phenyl, benzyl or phenoxy, to give a compound of the formula: ** (See formula) ** wherein R is as defined above and R1 is hydrogen, straight or branched chain lower alcohol having 1 to 5 carbon atoms, phenyl, benzyl or phenoxy; optionally followed by converting the latter compound to its non-toxic acid addition salt; and optionally also by separating an erythro- or threo-isomer from the resulting salt.
