A method for the direct conversion of bioglycerol to oxazoline was devised involving glycerol dehydration to acetol followed by its amination with aqueous ammonia.

Solvothermally prepared Mn3O4 showed excellent performance for veratryl alcohol oxidation to veratraldehyde due to formation of monoclinic and hausmannite phases.

Autogenous glycerol hydrogenolysis to 1,2-propanediol by aqueous phase reforming (APR) was investigated over supported nickel catalysts. Effect of reduction temperature on physico-chemical properties of catalysts played a significant role in tuning conversion and product selectivities. The formation of nickel aluminate (NiAl 2 O 4 ) spinel phase during catalyst reduction led to rearrangement of Ni species to obtain small and stable Ni particles. The catalyst activation temperature alters the extent of reduction of multivalent Ni species (Ni 0 , Ni + 2/ + 3 ) which facilitated glycerol dehydration and hydrogenation while suppressing CÀ C cleavage and thus avoiding undesirable side products. Additionally, presence of moderate BrØnsted/Lewis acid ratio of the catalyst promoted higher 1,2-PDO selectivity. In-situ glycerol hydrogenolysis involves glycerol dehydration to acetol with simultaneous reforming to H 2 and CO 2 and this hydrogen converts acetol to 1,2-PDO.
