Acid-catalyzed equilibrium of a mixture of 1,2- and 1,3-methyleneglycerol in 1,4-dioxane affords predominantly the 1,3-isomer via bridged acetal exchange. The minor 1,2-isomer is removed via sequential pivaloylation and tritylation to afford the desired 1,3-isomer in >99.5% purity. A symmetrically branched triglycerol is efficiently synthesized starting from the purified 1,3-isomer. Georg Thieme Verlag Stuttgart · New York.
Mesoporous Zr-SBA-16 catalysts for glycerol valorization processes: Towards biorenewable formulations
Gonzalez-Arellano, Camino,Parra-Rodriguez, Leticia,Luque, Rafael
, p. 2287 - 2292 (2014)
Zr-containing SBA-16 materials were utilized in glycerol valorization for the production of esters (via reaction with levulinic acid) and glycerol formal (GF) via acetalisation with paraformaldehyde. The materials were found to be highly active and selective for the production of valuable compounds from glycerol using benign by design solventless protocols which employ mild reaction conditions. Certain materials were also found to be highly reusable and stable under the investigated conditions.
A bifunctional catalyst based on Nb and v oxides over alumina: Oxidative cleavage of crude glycerol to green formic acid

A bimetallic vanadium and niobium oxide catalyst using alumina as support was developed for the conversion of crude glycerol from biodiesel production into formic acid. The high dispersion of the active oxide phase combined with the presence of acid and redox active centers resulted in a high glycerol conversion (>90% for 25 h) with a good selectivity for formic acid (~55%). This process is the first example of a heterogeneous liquid-phase process for the conversion of crude glycerol to formic acid, which is an important chemical intermediate currently derived from petroleum feedstock.

Paragraph 0029-0034, (2019/04/11)
The invention discloses a method for preparing glycerolformal. According to the invention, SO42-/Fe2O3-CNTS super acid is used as a catalyst for compounding glycerolformal, so that the method has theadvantages that reaction temperature is low, catalyst activity is high, no new water-carrying agent is brought, yield of reaction products is 95% or above and hexatomic ring products are high in proportion.
