Date Apr. 18, 1996A method of removing heteropoly compounds from polyethers, polyesters and/or polyether esters, which are contaminated with heteropoly compounds is described, which comprises adding, to the polymers or a solution thereof, an ether whose polarity is so low that its addition leads to the deposition of the heteropoly compound in a separate phase, and separating off the precipitated heteropoly compound phase. The polymer phase which remains is preferably purified further using a solid adsorbent.

Abstract: Propargyl chloride (I) is prepared continuously by reaction of propargyl alcohol (II) with a chlorination agent, in the presence of a catalyst (0.1-10 mol.% based on the amount of (II)), at 40-70 deg C. Continuous preparation of (I) comprises reaction of (II) with a chlorination agent in the presence of a catalyst. The chlorination agent, (II) and catalyst (0.1-10 mol.% based on the amount of (II) used) are added continuously into a reaction zone and reacted at 40-70 deg C.
