摘要:
The present invention relates to a process for the dehydration of alcohols, polyalcohols or alcoholates having at least one CH group in the alpha-position to the alcoholate or alcohol function to give alcenes or ethers, where the dehydration is carried out in ionic liquids of the general formula K+A-.
摘要:
The invention relates to a method for producing onium-alkylsulfonates by reacting an onium halogenide or carboxylate with a symmetrically substituted dialkyl sulphite or with a asymmetrically substituted dialkyl sulphite at temperatures ranging from 50 to 170 °C.
摘要:
The invention relates to a method for producing onium salts with a low chloride content by reacting an onium chloride with an acid. According to the invention, the hydrochloric acid that is produced can be removed by co-ordination with an organic solvent, which forms an azeotropic mixture with water, and by subsequent azeotropic distillation.
摘要:
The invention relates to the compounds of formula (I), wherein X, -Q1-Q2- and RF are defined as in claim 1, for use as ionic liquids, and to methods for producing the same.
摘要:
The invention relates to dyes of general formula (I) CAT+ Y- (I) wherein Y- represents an anion that is selected from the group of cyanoborates, fluoroalkyl phosphates, fluoroalkyl borates or imidates, and CAT+ is a cation selected from the group of azine, xanthene, polymethine, styryl, azo, tetrazolium, pyrylium, benzopyrylium, thiopyrylium, benzothiopyrylium, thiazine, oxazine, triarylmethane, diarylmethane, methine, acridine, quinoline, isoquinoline or quaternary azafluorenone dyes. The inventive dyes are used to dye plastic materials and plastic fibres, to produce flexographic printing inks, as ball point pen pastes, as stamping ink, to dye leather and paper, and to use in data acquisition systems, in reprographics, micro-colour filters, photogalvanism, laser technology, and in the photographic industry.
摘要:
The invention relates to a method for producing perfluoroalkyl phosphines, comprising at least one step in which at least one fluoro(perfluoroalkyl)phosphorane is reacted with at least one hydride ion donator, and the use of tris(perfluoroalkyl)phosphines as perfluoroalkylating reactants.
摘要:
The present invention relates to an amine of general formula (I), in which R?1 and R2¿ may be the same or different and represent each independently substituted or non-substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkinyl, aryl or trialkylsilyl. R?1 and R2¿ can also form together with the nitrogen atom to which they are bound a substituted or non-substituted cycloalkyl ring which may contain, together with the nitrogen atom, at least one other heteroatom selected from the group comprising nitrogen, oxygen and sulphur. R3 is selected from the group comprising hydrogen and methyl optionally substituted with 1 to 3 fluorine atoms, while R?4 and R5¿ may be the same or different and represent each independently substituted or non-substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl or alkinyl. This invention also relates to a salt thereof.
