Uniformly-sized porous cellulose beads functionalized with amidoxime groups were prepared for the first time using a microfluidic method N-methylmorpholine N-oxide (NMMO) monohydrate as solvent. The molten state dope in NMMO (cell/NMMO dope) disperse phase and hot mineral oil continuous used T-junction chip to produce uniformly-sized cell/NMMO droplets. Coagulation of droplet at high temperatur...

Synthesizing azoles from ortho-substituted anilines, CO2 and H2 has proved difficult due to the low nucleophilicity of which hinders their N-formylation, i.e., first step reaction. Herein, we demonstrate that R3SnX Lewis acids (LA), N-methylmorpholine (NMM) or DBU polyethyleneimine (PEI) N-formylmorpholine efficiently catalyse synthesis benzimidazole other by reductive coupling nucleophilic ami...

We have investigated the effect of several common buffers (10-mM formic acid, 10-mM ammonium acetate, and 100-mM ammonium acetate) on the ionization of a series of model compounds that are amenable to negative atmospheric pressure chemical ionization to determine the extent of ionization quenching that can occur. In addition, we have compared the sensitivity of these standard mobile phases to a...

Abstract Lignocellulosic residues (LRs) are one of the most abundant wastes produced worldwide. Nevertheless, unlocking full energy potential from LRs for biofuel production is limited by their complex structure. This study investigated effect N-methylmorpholine N-oxide (NMMO) pretreatment on almond shell (AS), spent coffee grounds (SCG), and hazelnut skin (HS) to improve bioconversion methane....

The aldol reaction of acetone with aldehydes in aqueous medium under catalysis by zinc-proline (Zn(L-Pro)2) and secondary amines such as proline, (2S,4R)-4-hydroxyproline (Hyp) and (S)-(+)-1-(2-pyrrolidinomethyl)pyrrolidine (PMP) is shown to proceed by an enamine mechanism, as evidenced by reductive trapping of the iminium intermediate, while the aldol reaction of dihydroxyacetone (DHA) under c...

4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees C leads to distintegration of the exine ;s...
