Green and sustainable chem. have gained substantial attention worldwide, and the efforts have been greatly appreciated for the substitution of Broensted acid catalysts from homogeneous to heterogeneous phases. In this perspective, a sulfonic acid-functionalized silica nanospheres (SAFSNS) catalyst was prepared by organosilylation-sulfonation on the surface of well-ordered silica nanospheres as a heterogeneous nanocatalyst. The physicochem. properties of nanocatalyst were well characterized by powder XRD, IR, TGA, DSC, NH3-TPD, N2 sorption, EDAX, and SEM techniques. The attainment of the anchoring of SO3H functionalization involving the Broensted acidities was found up to 0.35 mmol H+/g. The synthesized SAFSNS nanocatalyst ascertain the replacement of the highly toxic liquid phase acids to a stable, solid acid catalyst for the green esterification of carboxylic acids under solvent-free reaction conditions, showed reasonable to excellent esters yield (63-94%) in 3.5 h at 100°C with five times reusability without substantial diminution in catalytic proficiency. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Recommanded Product: Octyl acetate).
Octyl acetate (cas: 112-14-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: Octyl acetate
