Abstract
Process for the conversion of dimethyl ether into a mixture of substantially aliphatic hydrocarbons and water by means of a catalyst containing boron. The dimethyl ether is put in contact, at a temperature of over 250.degree. C., with a catalyst that consists of a crystalline modification of silica in whose crystal lattice a number of silicon atoms have been replaced by boron atoms. The amount of boron in the crystalline modificaton, expressed as the molar ratio of the oxides B.sub.2 O.sub.3 and SiO.sub.2, may vary between 0.0005 and 0.025.
