Abstract: The preparation of alkylaryl compounds takes place by a) reaction of a C 4 /C 5 -olefin mixture over a metathesis catalyst to prepare a C 4-8 -olefin mixture comprising 2-pentene, and optional removal of the C 4-8 -olefin mixture, b) removal of from 5 to 100% of the 2-pentene present in stage a) and subsequent reaction over an isomerization catalyst to give a mixture of 2-pentene and 1-pentene which is returned to stage a), c) dimerization of the C 4-8 -olefin mixture obtained in stage b) following removal in the presence of a dimerization catalyst to give a mixture containing C 8-16 -olefins, removal of these C 8-16 -olefins and optional removal of a partial stream thereof, d) reaction of the c 8-16 -olefin mixtures obtained in stage c) or of the partial stream with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds where, prior to the reaction, 0 to 60% by weight, based on the c 8-16 -olefin mixtures obtained in stage c), of linear olefins may additionally be added, e) optional sulfonation of the alkyl aromatic compounds obtained in stage d) and neutralization to give alkylarylsulfonates, where, prior to the sulfonation, 0 to 60% by weight, based on the alkyl aromatic compounds obtained in stage d), of linear alkylbenzenes may additionally be added if no admixing has taken place in stage d), f) optional mixing of the alkylarylsulfonates obtained in stage e) with 0 to 60% by weight, based on the alkylarylsulfonates obtained in stage e), of linear alkylarylsulfonate, if no admixing has taken place in stages d) and e).

Abstract: THE INVENTION DESCRIBES A PROCESS FOR THE PREPARATION OF NOVEL SURFACTANT ALCOHOLS AND SURFACTANT ALCOHOL ETHERS BY DERIVATIZATION OF OLEFINS HAVING FROM ABOUT 10 TO 20 CARBON ATOMS OR OF MIXTURES OF SUCH OLEFINS TO GIVE ALKANOLS, AND OPTIONAL SUBSEQUENT ALKOXYLATION, WHICH COMPRISES SUBJECTING A C4-OLEFIN MIXTURE TO METATHESIS, DIMERIZING THE RESULTING OLEFINS, AND THEN DERIVATIZING THEM TO GIVE SURFACTANT ALCOHOLS, AND OPTIONALLY ALKOXYLATING SAID ALCOHOLS. THE OLEFIN MIXTURE OBTAINED IN THE DIMERIZATION HAS A HIGH PROPORTION OF BRANCHED COMPONENTS AND LESS THAN 10% BY WEIGHT OF COMPOUNDS WHICH CONTAIN A VINYLIDENE GROUP. THE INVENTION FURTHER DESCRIBES THE USE OF THE SURFACTANT ALCOHOLS AND SURFACTANT ALCOHOL ETHERS TO GIVE SURFACTANTS BY GLYCOSYLATION OR POLYGLYCOSYLATION, SULFATION OR PHOSPHATION.

Abstract: Polymers (I), used in hair styling agents, are prepd. by radical-initiated copolymerisation of: (A) 5-50 wt.% (quat.) 1-vinyl imidazole; (B) 20-80 wt.% N-vinyl caprolactam; (C) 10-60 wt.% N-vinyl pyrrolidone; and (D) 0-30 wt.% additional radical copolymerisable monomer which forms a homopolymer with a Tg > 20 degrees C, with the proviso that the polymer is quaternised if (A) is 1-vinyl imidazole. Cosmetic hair and skin formulations contg. (I) as active ingredients are also claimed. Pref. (A) is 3-methyl-1-vinyl imidazolinium chloride or -methyl sulphate, or 3-ethyl-1-vinyl imidazolinium methyl sulphate. (D) is tert.-butyl acrylate. (I) is prepd. by copolymerisation of a mixt. comprising 10-30 wt.% 1-vinyl imidazole quaternised with di(m)ethyl sulphate as component (A), 40-60 wt.% (B), and 30-50 wt.% (C).

Abstract: Prodn. of high mol. polymers involves: (a) polymerising water-soluble, mono-ethylenically unsatd. monomers and opt. crosslinkers contg. non-conjugated ethylenically unsatd. double bonds. in the molecule and opt. water-insol. monoethylenically unsatd. monomers in aq. soln. in the presence of polymerisation initiators in a tubular reactor; and (b) forcing the gelatinous reaction mixt. from the reactor with an inert gas. The reactor has: (i) a conical taper at one end, so the ratio of the dia. (D1) of the reactor to the dia. (D2) at the end of the cone is (2-25); and (ii) the angle between D1 at the beginning of the cone and the inner wall of the cone of more than 45 and less than 90 degrees .
