Production of renewable oleo-furan surfactants by cross-ketonization of biomass-derived furoic acid and fatty acids

Synthesis of 2-dodecanoyl furan is a crucial step in the formulation of oleo-furan sulfonates as bio-surfactants from biomass-derived furans and vegetable-oil-derived molecules. Herein, cross-ketonization of 2-furoic acid and lauric acid is proposed to produce the bio-surfactant precursor. Among the commonly reported metal oxide ketonization catalysts, the inexpensive and abundant iron oxides are demonstrated as effective and recyclable catalysts, enabling up to 77% selectivity to 2-dodecanoyl furan at 56% lauric acid conversion. Catalyst characterization by X-ray diffraction, H2temperature-programmed reduction, and X-ray photoelectron spectroscopy indicates that Fe3O4is the catalytically active and stable phase.13C isotopic tracing experiments suggest that cross-ketonization on Fe3O4proceedsviaa β-keto acid intermediate.

Highly productive α-alkylation of ketones with alcohols mediated by an Ir-oxalamidato/solid base catalyst system

An Ir-oxalamidato complex in combination with a solid base (e.g., magnesium aluminometasilicate/Ca(OH)2) significantly improved the catalyst productivity in α-alkylation of methyl ketones with primary alcohols. Optimization through systematic variation of the oxalamidato ligand led to a practical turnover number (TON) of 10 000.40 000.

PROCESS FOR THE PREPARATION OF ALKOXYLATES COMPOSITIONS

A mixture of two alkoxylates surfactants, one being an aryl aliphatic carbinol alkoxylate, the other one being a dialiphatic carbinol alkoxylate, said mixture being useful for stabilizing emulsions and dispersions used in agricultural or pharmaceutical formulations. The alkoxylates surfactants may serve as substitutes for nonylphenol ethoxylates (NPE) and tristyrylphenol ethoxylates (TSE).
