Al-Modified Ti-MOR as a robust catalyst for cyclohexanone ammoximation with enhanced anti-corrosion performance

The skeleton desilication accompanied by Ti active sites leaching accounts for the dominant chemical deactivation reasons in the alkali liquid-phase ammoximation, which could be retarded by creating a protective Al-rich shell.

Improved Ti species distribution and hierarchical pores in TS-1: towards regeneration of TS-1 deactivated due to alkali corrosion

TS-1 deactivated in industrial cyclohexanone ammoximation can be effectively regenerated by hydrothermal treatment with TPABr and ethanolamine solution.

Seed-assisted synthesis of TS-1 crystals containing Al with high catalytic performances in cyclohexanone ammoximation

Using aluminosilicate zeolites seeds, Al atoms are introduced into the TS-1 crystals, resulting in high Lbvalue and more acid sites, which improve the catalytic activity in cyclohexanone ammoximation.
