    摘要： The invention relates to a method for producing ionic liquids consisting first in reacting an ionic liquid with an alkylate, a hydrogencarbonate, a carbonate, a carboxylate or a hydroxide and, afterwards in neutralising with an acid. The inventive ionic liquids contain a phoshonium and/ or ammonium cation and an anion selected from a group comprising halogenides, aryl sulfonates, alkyl sulfonates, sulphates, hydroxysulfats, alkylsulfates, hydrogencarbonates, carbonates, triflates and carboxylates. The inventive method makes it possible to introduce any desired anion into the ionic liquids.

    摘要： The invention relates to a method for isolating acids from chemical reaction mixtures by means of an auxiliary base, whereby this auxiliary base: b) forms a salt with the acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during the isolation of the liquid salt, and; c) the salt of the auxiliary base, together with the valuable product or with the solution of the valuable product, forms, in a suitable solvent, two non-mixable liquid phases. According to the invention, an alkyl imidazole is used as the auxiliary base and has a solubility, in 30 % by weight of sodium chloride solution at 25 °C, of 10 % by weight or less and whose hydrochloride has a melting point of less then 55 °C.

    摘要： The invention relates to a method for producing tertiary phosphines by reacting a compound of general formula (I) with (a) an alkali metal in an organic aprotic solvent and (b) a compound of general formula (II). In formula (I), A represents R1 or L2, B represents R2 or L3, where the groups R1 and R2 independently of one another stand for an organic group with respectively between 1 and 30 carbon atoms and said groups R1 and R2 can also be bonded together. The leaving groups L1 to L3 independently of one another represent halogen, alkyloxy with between 1 and 10 carbon atoms or aryloxy with between 6 and 10 carbon atoms. In formula (II), the group R3 represents an organic group with respectively between 1 and 30 carbon atoms and the leaving group L4 represents halogen, alkyloxy with between 1 and 10 carbon atoms or aryloxy with between 6 and 10 carbon atoms. The reaction mixture that is obtained is hydrolysed using an aqueous base with a pH value of > 10 and the organic phase is then separated from the aqueous phase.

    摘要： Disclosed is a method for producing purified 1,3-substituted imidazolium salts of general formula (I) by reacting a 1,3-substituted imidazolium salt of general formula (II) with a strong base at a temperature ranging between 20 and 250 °C while distilling off the formed 1,3-substituted imidazol-2-ylidene. According to the inventive method, the distilled 1,3-substituted imidazol-2-ylidene is contacted in a gaseous state with the protonic acid HaA (III), and/or the distilled 1,3-substituted imidazol-2-ylidene is directed in a gaseous or condensed state into a distillation receiver containing said protonic acid HaA (III).
