摘要： Malononitrile is prepared by the short time high temperature reaction of gaseous acetonitrile and cyanogen chloride in the molar ratio of acetonitrile to cyanogen halide of above 1 characterized in that the well mixed reaction components are reacted at an average temperature below 800.degree. C. and the reaction is quenched to condense acetonitrile and malononitrile by introducing a cooling medium into the reaction system.

摘要： Cyanogen chloride and hydrogen chloride are produced by reacting hydrogen cyanide and chlorine, separating from the gaseous mixture on the one hand hydrogen chloride and on the other hand cyanogen chloride which in a given case can also contain chlorine, by absorption in a halohydrocarbon which has a boiling point between that of cyanogen chloride and cyanuric chloride and after distillative separation of the dissolved cyanogen chloride-chlorine mixture returning the solvent to the absorption column, the process includesA. adding as the solvent for the absorption a trifluoromethyl substituted aromatic hydrocarbon or halohydrocarbon or a mixture of such trifluoromethyl substituted aromatic hydrocarbons or halohydrocarbons,B. subjecting the gas mixture consisting of cyanogen chloride, hydrogen chloride and in a given case chlorine after leaving the reactor for the chlorination of hydrogen cyanide and before entrance into the absorption column to a pretreatment with the solvents set forth under (a) at a temperature between 80.degree.C. and the boiling point of the solvent and/orC. either converting the N-chloro-chloroformimide chloride formed in small amounts from the chlorine and cyanogen chloride in the course of the absorption and distillation into the insoluble chloroformimide chloride hydrochloride by gassing the solvent with hydrogen chloride and separating the insoluble hydrochloride in conventional manner and/or withdrawing the N-chloro-chloroformimide together with some cyanogen chloride and solvent of the previously named distillation column for separation of the cyanogen chloride by means of a side outlet, and in a second subsequently provided distillation column separating into solvent and pure N-chloro-chloroformimide chloride, whereby then the latter can be conducted both into the cyanogen chloride reactor and also, if connected to a plant for the production of cyanuric chloride, into the trimerization reactor for cyanogen chloride and/orD. subjecting the solvent contaminated with byproducts by the suspension resulting from the pretreatment and/or accumulating in the sump of the distillation column for the separation of the cyanogen chloride completely or in a partial stream to an aqueous alkaline treatment or in combination with a cyanuric chloride condensation plant leading the suspension formed in the pretreatment to the cyanuric chloride condensation column.

摘要： A gear actuator for engaging and disengaging gears in an automatic manual transmission has a single working piston or two working pistons provided with a first working piston surface and a second working piston surface. An auxiliary piston is provided also. A pressure control valve controls a pressure supplied to the second working piston surface. A shut-off valve is provided. The first working piston surface and the pressure valve are supplied with a system pressure of a hydraulic system. The first working piston surface and the pressure control valve can be decoupled from the system pressure of the hydraulic system by the shut-off valve.

摘要： A method for determining the starting capability of an internal combustion engine of a motor vehicle, which can be started by an electric motor powered by a battery, including detecting first battery parameter values during a successful starting sequence of the internal combustion engine at a first time, detecting second battery parameter values at a second time following the first time, determining at the second time the expected battery voltage for a starting sequence of the internal combustion engine taking place at a third time based on the detected first and second battery parameter values, and comparing the battery voltage expected at the third time with a predetermined threshold value in order to derive therefrom the starting capability of the internal combustion engine.
