    Abstract: PROBLEM TO BE SOLVED: To provide a method for isolating NGH from a mixture comprising the NGH, a low boiling point and a high boiling point products, and an inorganic salt by which the pure NGH can be produced without generating an colored impurity in high yield and more simply than the conventional method, and good controls at every step can be enabled, and which is not so unstable that the interruption of the treatment is caused. SOLUTION: A mixture is fed to a wiping evaporator 3 in the first separation zone comprising the wiping evaporator 3 and a heat-exchanger 6, and a mixed material flow comprising a high boiling point product and an inorganic salt is discharged as a bottom product. The distillate flow is fed to the heat-exchanger 6 and the condensed product flow formed at the heat-exchanger 6 is fed to a rectifier 8 in the second separating zone comprising the rectifier 8, a second evaporator 17, the heat-exchanger 10. The distillate from the rectifier 8 is condensed at the heat-exchanger 10 and the condensed material flow is taken out as a low boiling point product flow. NGH is condensed as a side flow distillate, and a bottom product flow comprising the NGH and the high boiling point product is fed to the second evaporator 17. The discharged flow from the second evaporator 17 is recycled and returned to a lower zone of the rectifier.

    Abstract: The invention relates to a method for the production of metylamines by means of gas phase reaction from methanol and ammonia as educts in the presence of a heterogeneous catalyst at a pressure in the region of 15 - 30 bars. Said educts are vaporised in one or several heat exchangers (1, 2, 3) in order to overheat an educt gas flow and are subsequently guided to a reactor (4). The educts can be mixed in the inlets of one of the heat exchangers (1, 2, 3) or at one remaining position in a heat exchanger (1, 2, 3). A product gas flow containing monomethylamine, dimethylamine and trimethylamine, in addition to reaction auxiliary products, is removed from the reactor (4). In order to regulate the reactor admission temperature of the educts to a temperature in the region of 360 DEG C - 370 DEG C, the educt gas flow or the product gas flow is guided partially or completely through an adjustable valve (5) enabling the pressure and the condensation temperature to be varied.

    Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I)in which R is hydrogen or C1- to C3-alkyl; R and R independently of one another are C1- to C4-alkyl, or R and R together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.
