标 题:One-pot synthesis of high-quality metal chalcogenide nanocrystals without precursor injection
发明人：CAO YUNWEI CHARLES
权利人:UNIV FLORIDA
摘要:A method of homogeneously forming metal chalcogenide nanocrystals includes the steps combining a metal source, a chalcogenide source, and at least one solvent at a first temperature to form a liquid comprising assembly, and heating the assembly at a sufficient temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals. The plurality of metal chalcogenide nanocrystals are then grown without injection of either the metal source or the chalcogenide source at a temperature at least equal to the sufficient temperature, wherein growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals. An optional nucleation initiator can help control the final size of the monodisperse crystals. Such synthesis, without the need for precursor injection, is suitable for the industrial preparation of high-quality nanocrystals.

摘要:A method of forming monodisperse metal chalcogenide nanocrystals without precursor injection, comprising the steps of: combining a metal source, a chalcogen oxide or a chalcogen oxide equivalent, and a fluid comprising a reducing agent in a reaction pot at a first temperature to form a liquid comprising assembly; increasing the temperature of the assembly to a sufficient-temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals; and growing the plurality of metal chalcogenide nanocrystals without injection of either the metal source or the chalcogen oxide at a temperature equal to or greater than the sufficient-temperature, wherein crystal growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals. Well controlled monodispersed CdSe nanocrystals of various sizes can be prepared by choice of the metal source and solvent system.

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.

标 题 :Polysulfide polyols, their production and use in the synthesis of polyurethanes
发明人：BALBO BLOCK MARCO; RHUDY KEVIN; FLECKENSTEIN CHRISTOPH
权利人:BASF SE
摘要:The present invention relates to sulfur containing polyols, a process for their production by reaction of at least one unsaturated alcohol A with elemental sulfur, wherein the unsaturated alcohol A has only one carbon-carbon double bond-unsaturation per molecule. The sulfur containing polyols are used in the production of polyurethanes, in particular rigid foam polyurethanes, for high-temperature pipe insulation applications.
