摘要： A method for the preparation of catalysts, particularly suitable for the hydrogenation of organic compounds, according to which method a catalytic element, preferably selected from the VIII Group elements, is supported on the outer surface of an adsorbent carbon, said method being characterized by the fact that:(a) said carbon containing an amount of ash lower than 1% by weight, is suspended in water;(b) a liquid immiscible with water is added to the suspension obtained according to (a), the volume of said immiscible liquid being substantially equal to or lower than the volume of the carrier's pores;(c) an aqueous solution, containing a compound of the catalytic element, is brought into contact with the suspension obtained according to (b).

摘要： A process for extracting vinyl chloride monomer from polyvinyl chloride latexes is disclosed, characterized in that the latex is continuously flowed on and along a heat exchange surface in the form of a thin film having a thickness ranging from 0.5 to 1.2 mm, said latex having a temperature between 40.degree. and 70.degree. C. and under a pressure ranging from 45 to 210 mm Hg., and for a time ranging from 10 to 70 seconds. The gaseous vinyl chloride monomer is removed concurrently with the flow of the latex. Suitable apparatus is also disclosed.
