    • 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 °C - 370 °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.
    • 本发明涉及一种在非均相催化剂存在下,在15-30巴的压力下,通过甲醇和氨的气相反应生产甲胺的方法。 所述排出物在一个或多个热交换器(1,2,3)中蒸发,以便使过渡气体流过热并随后被引导至反应器(4)。 排出口可以在热交换器(1,2,3)的一个入口处或在热交换器(1,2,3)中的一个剩余位置处混合。 从反应器(4)除去含有一甲胺,二甲胺和三甲胺的产物气流,以及反应助剂。 为了将出口的反应器入口温度调节到360℃至370℃的温度,通过可调节阀(5)部分或完全地引导排气流或产物气流,使压力 并且冷凝温度要变化。
