Esterification reactions of some polyols and diols were investigated in the presence of SnO2 and nano-SnO2 and the results were compared with the catalyst-free conditions. High conversions were obtained for most of the reactions in the presence of SnO2 and nano-SnO2 which shows the high catalytic activity of SnO2 and nano-SnO2</sub...

Antimicrobial epsilon-poly-L-lysine (ePL) is secreted by Streptomycetaceae bacteria, and the mechanism of ePL biosynthesis remains to be elucidated. We previously reported that an unknown ePL derivative accumulates in the culture medium of ePL-producing bacteria when glycerol is added to the culture medium (Nishikawa and Ogawa, Appl. Environ. Microbiol. 68:3575-3581, 2002). In this study, by us...

Novel polyols were synthesized by controlled polymerization of hydroxylated fatty acids from methyl soyate. Polymerization of methyl esters of hydroxy fatty acids gives a hyperbranched (HB) product with different content of hydroxyl groups depending on the degree of conversion. Molecular weights, functionality and hydroxyl equivalent of polyols can be controlled by controlling the degree of con...

Polyols and polyacrylates have a wide range of applications in polymer synthesis as monomers, initiators, or building blocks variety polymerization reaction types. With an ever-growing need to reduce the global dependency on fossil fuels, finding bio-based/renewable sources for these compounds is now critical. Herein, alkene moieties common, abundant terpenes are functionalized via oxidation ex...
