Hernandez-Ramos, Fabio published the artcileRenewable Biopolyols from Residual Aqueous Phase Resulting after Lignin Precipitation, COA of Formula: C4H8O3, the main research area is renewable biopolyol production residual aqueous phase lignin precipitation.
The aim of this work was to obtain two biopolyols from the liquid residue resulting from the precipitation of lignin contained in two different black liquors, Eucalyptus globulus organosolv black liquor (EOBL) and Pinus radiata organosolv black liquor (POBL), thus adding value to this residue. Eucalyptus organosolv polyol (EOP) and Pine organosolv polyol (POP) were characterized to know their viscosity, hydroxyl number (IOH), and functionality according to the corresponding standard American Society for Testing Materials (ASTM). The mol. weight of the biopolyols was measured through gel permeation chromatog. (GPC); the chem. structure and composition were characterized by Fourier transform IR (FTIR) and gas chromatog.-mass spectrometry (GC-MS), resp.; and the thermal degradation (TGA) of the two biopolyols was determined The biopolyols showed suitable properties to be employed in the production of polyurethanes (PU).
ACS Sustainable Chemistry & Engineering published new progress about Density. 623-50-7 belongs to class esters-buliding-blocks, name is Ethyl 2-hydroxyacetate, and the molecular formula is C4H8O3, COA of Formula: C4H8O3.
