标 题:Method for the production of alkyl aryl sulphonates
发明人：NARBESHUBER THOMAS; STEINBRENNER ULRICH; KRACK GERHARD
摘要:The preparation of alkylaryl compounds takes place by n 1) preparation of a mixture of, on statistical average, predominantly monobranched C 10-14 -olefins by n a) reaction of a C 4 -olefin mixture over a metathesis catalyst for the preparation of an olefin mixture comprising 2-pentene and/or 3-hexene, and optional removal of 2-pentene and/or 3-hexene, followed by dimerization of the resulting 2-pentene and/or 3-hexene over a dimerization catalyst to give a mixture comprising C 10-12 -olefins, and optionally removal of the C 10-12 -olefins, or n b) extraction of predominantly monobranched paraffins from kerosene cuts and subsequent dehydrogenation, or n c) Fischer-Tropsch synthesis of olefins or paraffins, where the paraffins are dehydrogenated, or n d) dimerization of shorter-chain internal olefins, or n e) isomerization of linear olefins or paraffins, where the isomerized paraffins are dehydrogenated, n 2) reaction of the olefin mixture obtained in stage 1) with an aromatic hydrocarbon in the presence of an alkylation catalyst which contains zeolites of the faujasite type.

摘要:A composition is provided, wherein the composition comprises a water-swellable, water insoluble polymer, a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding to the hydrophilic polymer, and a whitening agent, preferably a peroxide. The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.

标 题 :Alkoxylated polymer and synthesis thereof with reduced dioxane formation
发明人：HUEFFER STEPHAN; ETTL ROLAND; GARCIA MARCOS ALEJANDRA
权利人:BASF SE
摘要:The present application relates to an alkoxylated polymer consisting of (i) triethanolamine (TEA) and/or triisopropanolamine (TIPA) units and (ii) chains of alkylene oxide units, where the components are chosen so as to give rise to a biodegradable polymer with washing power that can be synthesized with reduced dioxane formation. The application is also directed to a cleaning composition comprising the alkoxylated polymer, to the use of the inventive polymer for boosting the primary washing power of washing compositions, to a cleaning method and to the use of (i) triethanolamine (TEA) and/or triisopropanolamine, (ii) ethylene oxide (EO) and (iii) propylene oxide (PO) for low-dioxane production of an alkoxylated polymer.
