Verfahren zur Herstellung von Methylalkohol aus Chlormethan.
Bekanntlich kann man Methan seit langer Zeit fast kostenlos gewinnen, und zwar entweder aus Erdgas oder durch synthetische Darstellung nach verschiedenen katalytischen Verfahren. An Versuchen zur Herstellung wertvoller Methylderivate aus diesem Kohlenwasserstoff hat es nicht gefehlt. Als einfachster und aussichtsreichster Weg kam folgender in Betracht :

Process for the production of methyl alcohol from chloromethane.
It is well known that methane has been obtainable almost free of charge for a long time, either from natural gas or by synthesis using various catalytic processes. There has been no lack of attempts to produce valuable methyl derivatives from this hydrocarbon. The easiest and most promising route could be:
EMI1.1
These reactions have long been known as the mode of formation of methyl alcohol, but one

Technically useful processes have already been worked out for the preparation of monochloromethane, but the seemingly simple task is to let the chlorine through in the chloromethane

Circumstances, especially at higher temperatures. can be carried out more quickly and nevertheless with good yields. could not be foreseen.
The inventor has found that, depending on the working conditions, two kinds of processes actually take place, namely:

The nature of the new process is best illustrated by a practical example. An autoclave equipped with a stirrer. the one working pressure up to

When this temperature is reached, the pressure gauge of the autoclave will be approximately 12 atm.

Methane silver pressure is an essential characteristic of the new process, because the rate of reaction depends to a large extent on its value.
