    Abstract: A gas mixture (obtained by thermal cracking of hydrocarbons followed by quenching of the cracked gas and freed from carbon dioxide and water) is separated into a gas mixture containing hydrogen, carbon monoxide and methane and another gas mixture containing ethylene, acetylene and higher hydrocarbons by (a) cooling the gas mixture which is at superatmospheric pressure in at least one condensation stage to a temperature which is above the solidification temperature of acetylene mixed with the other condensed constituents, (b) separating the condensate thus obtained and subdividing it in a rectifying column into a first mixture containing C2 hydrocarbons and a second mixture containing C3 and higher hydrocarbons, and (c) freeing the residual gas remaining from (a) from residual acetylene and ethylene in a scrubber by treatment with some of the mixture consisting of C3 and higher hydrocarbons from (b).

    Abstract: Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.

    Abstract: Production of alkynols and/or alkynediols by reaction of acetylene with aldehydes in a liquid reaction medium in the presence of a heavy metal acetylide as catalyst and in the presence or absence of basic reagents, at least one of the starting materials being introduced in gaseous form. The catalyst is suspended in the liquid medium and during the reaction a portion of the reaction medium is withdrawn and returned at the entry point below the level of the liquid of the gaseous starting material(s) at a speed of 5 to 100 meters per second into the reaction medium and is introduced into a chamber (located in the reaction medium and extending in the direction of the liquid returned) whose inlet opening has a mean diameter from twice to twenty times the mean diameter of the liquid nozzle and whose length is three to thirty times ints hydraulic diameter. The products are important intermediates for example for the production of solvents or may be used in electrolytic baths.
