| titleOfInvention | Preparation of methyl chloride |
| abstract | PURPOSE: To obtain methyl chloride in high yield and purity, at lower temperatures in a high reaction rate and a longer catalyst life in the reaction of methyl alcohol with hydrogen chloride, by using a quaternary ammonium halide salt as a catalyst. n CONSTITUTION: Methyl alcohol in an amount of about 10W30% excess, is reacted with hydrogen chloride in the presence of a quaternary ammonium halide salt, preferably a quaternary salt of pyridine, more preferably N-methyl pyridinium chloride, at about 100W200°C, preferably 130W150°C, to give methyl chloride at low temperatures at a sufficiently high reaction rate. This method has advantages as follows: very little dimethyl ether is formed as a by-product and the purification after the readily achieved due to the difficult entrainment of the catalyst by the methyl chloride. The catalyst has a very long life, and the reaction volume for a given production may be smaller than the conventional one. n COPYRIGHT: (C)1981,JPO&Japio |
