متن کاملCorrelating physical changes and enhanced enzymatic saccharification of pine flour pretreated by N-methylmorpholine-N-oxide.
Pretreatment of lignocellulosic biomass by N-methylmorpholine-N-oxide (NMMO), a solvent used in the textile industry to dissolve cellulose for production of regenerated cellulose fibers, was observed to enhance significantly enzymatic saccharification and fermentation. The enhancement was speculated to have been caused by reduced cellulose crystallinity after dissolution and precipitation proce...
متن کاملCellulosic films obtained from the treatment of sugarcane bagasse fibers with N-methylmorpholine-N-oxide (NMMO).
Ethanol/water organosolv pulping was used to obtain sugarcane bagasse pulp that was bleached with sodium chlorite. This bleached pulp was used to obtain cellulosic films that were further evaluated by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). A good film formation was observed when temperature of 74 degrees C and ba...
متن کاملATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کامل(Z)-N-(2-Chlorobenzylidene)aniline N-oxide
In the title compound, C(13)H(10)ClNO, the central C-N bond has considerable double-bond character and the N-O bond indicates a formal negative charge on the O atom. The mol-ecule is stabilized by an intra-molecular C-H⋯O hydrogen bond. The geometry about the C=N bond is Z [C-C-N-O torsion angle = -4.2 (3)°] and the phenyl and benzene rings are trans-oriented around the C=N bond. The phenyl and...
