Zhang, Jianghua published the artcileEfficient production of medium-chain structured phospholipids over mesoporous organosulfonic acid-functionalized SBA-15 catalysts, Synthetic Route of 110-42-9, the main research area is phospholipid mesoporous organosulfonic acid silica functionalized catalyst.
It is highly desirable that efficient recoverable heterogeneous catalysts should be developed to replace the costly biocatalysts used in producing structured phospholipids (SPLs) with medium-chain fatty acids (MCFAs). Thus, mesoporous Pr and Ph sulfonic acid-functionalized SBA-15 materials synthesized via surface modification methods were investigated for the soybean lecithin interesterification with Me caprate or caprylate. The physicochem. properties of the synthesized solid acids were deeply studied by small-angle X-ray diffraction, SEM, transmission electron microscopy, Fourier transform IR and pyridine adsorption, etc. to build the possible structure-performance relationships. The results revealed that amounts of organosulfonic acid groups were successfully grafted onto the SBA-15 support, and most of the surface acid sites contained in the as-prepared organic-inorganic hybrid samples were assigned as strong Brönsted acid sites. Notably, the functionalized SBA-15 materials exhibited promising catalytic behaviors in producing MCFA-enriched SPLs under mild conditions (40°C, 6 h) when compared with com. Amberlyst-15 and typical phospholipases or lipases, mostly due to their high surface area, ordered structure and adequate Brönsted acid sites. Besides, the as-prepared materials could be easily recycled five times without obvious deactivation. This work might shed light on alternative catalysts for SPL production instead of the costly enzymes.
