Effects of Extraction Conditions on the Characteristics of Ethanol Organosolv Lignin from Bamboo (Phyllostachys pubescens Mazel)
The structure and properties of ethanol organosolv lignin (EOL) extracted from bamboo under various conditions were characterized. EOL yield increased at high temperatures of 160 to 200 °C and a reaction time of 1 to 3 h. The nitrogen content in lignin was low, with a maximum of 0.62%. The carbon content increased with increasing temperature and prolonged time, whereas oxygen content showed an ...
متن کاملFractionation of Hemicelluloses and Lignin from Rice Straw by Combining Autohydrolysis and Optimised Mild Organosolv Delignification
An integrated strategy was followed to valorise rice straw, one of the most relevant biomass feedstocks available worldwide, to selectively recover solubilised hemicelluloses and lignin. The pathway encompassed the use of autohydrolysis to hydrolyse the hemicelluloses and an ethanol-based organosolv process to solubilise lignin. Several autohydrolysis conditions were assayed with the best resul...
متن کاملThe Bu4NI-catalyzed alfa-acyloxylation of ketones with benzylic alcohols.
The Bu4NI-catalyzed reaction of ketones with benzylic alcohols was achieved, leading to alfa-acyloxycarbonyl compounds in moderate to good yields. This metal-free procedure featured the employment of facilely and commercially available starting materials and TBHP as a clean oxidant with high atom economy.
متن کاملCross-coupling of benzylic acetates with arylboronic acids: one-pot transformation of benzylic alcohols to diarylmethanes.
Benzylic acetates reacted with arylboronic acids in the presence of a DPEphos-[Pd(eta3-C3H5)Cl]2 catalyst when tert-amyl alcohol was used as a solvent, and the catalytic cross-couplings produced diarylmethanes in high yields (up to 94% isolated yield).
متن کاملRegioselective N-alkylation of 2-aminobenzothiazoles with benzylic alcohols.
The preparation of 2-(N-alkylamino)benzothiazoles via regioselecive N-alkylation of 2-aminobenzothiazoles has been accomplished by using benzylic alcohols as alkylating agents.
