PRODUCTION OF 3-METHYLBUT-1-EN BY MEANS OF DEHYDRATION OF 3-METHYLBUTANE-1-OL

摘要

The object of the invention is a method for producing 3-methylbut-1-en by means of dehydrating 3-methylbutane-1-ol at an aluminum-containing oxide in a temperature range of 200 to 450°C in the gaseous or liquid/gaseous mixture phase, characterized by an aluminum-containing oxide having mostly mesoporous pore structure is being used, which: a) relative ratio of macropores is less than 15%; b) contribution of the pore diameter has a monomodal maximum in the region of the mesopores of 3.6 to 50 nm; c) average pore diameter of all pores in the region of the meso- and macropores ranges from 5 to 20 nm; d) composition consists of gamma-aluminum oxide of more than 80%.
