Abstract: The present invention is related to the use of specific derivatives of diphosphines as flame retardants in aromatic and heteroaromatic epoxy resins and to a method for reducing the flammability of organic material comprising aromatic and/or heteroaromatic epoxy resins in which the specific derivates of diphosphines are incorporated. More-over, the invention is related to an aromatic and/or heteroaromatic epoxy resin composition containing aromatic and heteroaromatic epoxy resin as such or in processed form and incorporated in the aromatic and/or heteroaromatic epoxy resin at least one of the derivatives of diphosphines in an amount of from 1 to 35% by weight, based on the weight of the aromatic and/or heteroaromatic epoxy resin.

Abstract: The invention relates to a method for the distillation of ionic liquids. According to said method, in one step the pressure is set to a value below the ambient pressure and in a subsequent step, the ionic liquid is heated to a temperature ranging between 60 °C and 350 °C. The method is used in particular for purifying ionic liquids.

Abstract: The invention relates to a method for the production of an ionic compound, comprising at least one cation with a quaternary sp2-hybridised nitrogen atom, whereby a compound with a double-bonded nitrogen atom is reacted with a dialkyl sulphate, using both alkyl groups of the dialkyl sulphate and the ionic compound thus obtained with sulphate anions is optionally subjected to an ion-exchange.

Abstract: 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 R 1 or L 2 , B represents R 2 or L 3 , where the groups R 1 and R 2 independently of one another stand for an organic group with respectively between 1 and 30 carbon atoms and said groups R 1 and R 2 can also be bonded together. The leaving groups L 1 to L 3 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 R 3 represents an organic group with respectively between 1 and 30 carbon atoms and the leaving group L 4 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.
