Abstract: Process for prepn. of Cl atom- and SO2Cl gp. - substd. 5 + C alkanes, by reaction of >=1 mol Cl and 1 mol SO2 for each mol alkane, takes place with recycling of 3-40 (5-20) wt. % of reaction prod. leaving reaction chamber to reactor. Raw materials are charged upwards, at gas layer velocity 2-30 m/sec., for a gas layer dwelling period of 2 - 60 secs. to a reaction chamber the longitudinal axis of which forms an angle of 1.5-30 degrees with the horizontal. Prods. can be saponified to alkali sulphonates. Recycling step reduces quantity of unreacted alkanes and over-chlorinated - or over-sulphochlorinated cpds. and prevents discolouration. Saponified products are excellent wetting agents. Heat-transfer from reaction mixt. to tubular reactor walls is improved. Process is photolytic. All right-sources radiating in visible range can be used, esp. those having high proportion of radiation at wave-length 3000-5000 angstroms.

Abstract: Process for preparing opt. branched alkane sulphochlorides (I) by reacting alkali or NH4 salts of terminal 1-20C alkanesulphonates (II) with SOCl2 in the presence of >=1 formic acid amide and opt. inert organic solvents takes place in the presence of catalytic quantities of >=1 salt of transition metals having degree of oxidn. +2. (I) are intermediates for prepn. of the free sulphonic acids, sulphonic acid anhydrides and esters, sulphamides, sultones, sulphones, alkyl chlorides (by SO2 dissocation) and mercaptans (by reduction). Process is safe, economical and leads to high yields.

Abstract: 2-Ethylhexenal which is essentially free from water and from sodium hydroxide solution is obtained from the reaction product of n-butyraldehyde which contains sodium hydroxide solution and forms an emulsion, when the reaction product is treated with beach sand and the aqueous sodium hydroxide solution, which is separated off in the form of a layer, is removed after the treatment.

Abstract: Shell-and-tube heat exchanger having an inlet opening for product vapour, inlet and and outlet openings for cooling agent which is conducted in the heat exchanger (transfer) tubes, a purge stub for removing inert gases, and a discharge stub for product condensate, in which a) the shell-and-tube heat exchanger (1) is arranged vertically, b) the arrangement of the heat exchanger tubes (2) in the region of the side where the product vapour flows at first has large spacings, which are increasingly reduced in the course of the path of the main flow, and c) a plurality of purge stubs for inert gases (5) are arranged one above another opposite the inlet opening for product vapour (4) in the region of the tightest packing of the heat exchanger tubes (2).
