PRODUCTION OF 3-METHYLBUT-1-EN BY MEANS OF DEHYDRATION OF 3-METHYLBUTANE-1-OL |
摘要 |
<p>The invention relates to a process for preparing 3-methyl-1-butene by dehydration of 3-methyl-1-butanol over an aluminium-containing oxide in the temperature range from 200 to 450° C. in the gas phase or mixed liquid/gas phase, characterized in that an aluminium-containing oxide having a predominantly mesoporous pore structure whose: a) relative proportion of macropores is less than 15%; b) distribution of the pore diameter has a monomodal maximum in the range of mesopores from 3.6 to 50 nm; c) average pore diameter of all pores is in the range of mesopores and macropores from 5 to 20 nm; d) composition comprises more than 80% of gamma-aluminium oxide, is used.</p> |
