Abstract
A process for selectively making 2-alkenes from a NAO using a mesoporous catalyst that has been surface modified with a Brönsted acid compound. The Brönsted acid compound has a reactive silane connector, an organic linking group, and a Brönsted acid group. The mesoporous catalyst has an average pore diameter in a range of about 12 to about 100 Angstroms and a surface area of between about 400 to about 1400 m2/gram.
Claims20
A mesoporous catalyst having a surface that has been grafted with a substance comprising a Brönsted acid compound, the Brönsted acid compound comprising a reactive silane connector, an organic linking group, and a Brönsted acid group.
A mesoporous catalyst having a structure as follows:
- MP—O—Si-L-BA,
- wherein MP comprises a mesoporous silicate, is oxygen, Si is silicon, L comprises an organic linking group, and BA comprises the Brönsted acid group, and wherein the surface of the mesoporous silicate has been grafted with the —O—Si-L-BA group.
