Acid Functionalization Of SBA-15 Mesoporous Catalyst For Glycerol Esterification To Monoglyceride

In order to exploit the glycerol stream, its transformation into monoglyceride was carried out in the present study. Monoglyceride was produced through glycerol esterification with lauric acid using acid functionalized Santa Barbara no.15 (SBA-15) mesoporous material as catalyst due to high surface...

The acid functionalized SBA-15 catalysts were synthesized by incorporating two different acid sites, i.e. propylsulfonic acid and sulphated zirconia, on the SBA-15. The SBA-15 incorporated with propylsulfonic acid (SBA-15SO3H) was prepared by refluxing a mixture of SBA-15, dry toluene, trimercaptopropyl trimethoxysilane (MPTMS) at 105 oC, followed by soxhlet extraction for 24 h to propylthiol groups. The SBA-15SO3H catalyst was obtained by oxidation of the thiol group ( -SH) to sulfonic acid form (–SO3H).
