Abstract

Способ получения изобутилена разложением метил-третично-бутилового эфира на гетерогенном катализаторе при повышенной температуре, отличающийся тем, что в качестве катализатора используют кальций-боро-фосфатный катализатор и процесс проводят при атмосферном давлении, в присутствии водяного пара при следующих условиях: температура 200-250°C, объемная скорость подачи МТБЭ 1,0-2,0 ч-1. The method of producing isobutylene by decomposition of methyl tertiary butyl ether on a heterogeneous catalyst at an elevated temperature, characterized in that the catalyst is a calcium boron phosphate catalyst and the process is carried out at atmospheric pressure in the presence of water vapor under the following conditions: temperature 200-250 ° C, the volumetric feed rate of MTBE is 1.0-2.0 h-1.
