ABSTRACT OF THE DISCLOSURE The method of preparing isoprene and isoamylenes consists in that a gaseous mixture of isobutylene and methyl alcohol is brought in contact with a catalyst, namely aluminum oxide or tantalum pentoxide, at a temperature of 250 to 500°C. It is recommendable that use should be made of aluminium oxide modified with an oxide of at least one of the following elements: molybdenum, tungsten, chromium, zirconium, titanium, vanadium, and cobalt. Moreover, it is possible to use alu- minium oxide modified with a sulphate of at least one of the following elements: zirconium and chromium. A combination of both modifications is also possible. The yield of ??oprene obtained by the proposed method is 16 to 20 mol. per cent, with respect to the passed methyl alcohol, and the yield of isoamylenes is 25 to 30 mol. per cent.
