BAMO/NMMO Copolymer with Polyester Initiation
Propellants, Explosives, Pyrotechnics, 1997AbstractIn order to improve of mechanical properties at low temperature region, 3,3‐bis(azidomethyl)oxetan (BAMO), 3‐nitratomethyl‐3‐methyloxetane (NMMO) and polyester (PE) copolymer were synthesized by using polyester initiator with boron trifluoride etherate.

Bioresource Technology, 2014
The effects of N-methylmorpholine-N-oxide (NMMO) pretreatment on barley straw and forest residues were investigated for biogas production. The pretreatments were performed at 90°C with 85% NMMO for 3-30h. The best pretreatment conditions resulted in 100% improvement in methane yield during the subsequent digestion compared to that of the untreated ...

Green Chemistry, 2021
Biomass pretreatment with aqueous NMMO and digestion in GVL are common in biorefineries but their combination can lead to output loss, byproduct generation and uncontrollable reactions. The chemistry of the NMMO/GVL system is investigated in detail.

Thermodynamic Interaction Parameters for the System Water/NMMO Hydrate
The Journal of Physical Chemistry B, 2008Vapor pressures of water were measured for aqueous solutions of N-methyl-morpholine N-oxide (NMMO) at 80, 90 and 100 degrees C. The Flory-Huggins interaction parameters, chi, calculated from these data as a function of phi, the volume fraction of NMMO, are negative at all concentrations; at low phi, they decrease by more than a factor of 2 as T is ...

Graphene oxide/cellulose composite using NMMO monohydrate
Carbohydrate Polymers, 2011Abstract Graphene oxide (GO)/cellulose composite films were prepared by using an N-methylmorpholine-N-oxide (NMMO) monohydrate solvent. NMMO was an excellent dispersing agent for the GO as well as an environmentally friendly solvent for cellulose.

Kinetics of Precipitation of Cellulose from Cellulose−NMMO−Water Solutions
Biomacromolecules, 2005The regeneration of a solid, crystallized cellulose solution in a N-methylmorpholine-N-oxide (NMMO)-water mixture was studied by measuring the diffusion coefficient of both the water uptake from the regenerating bath and the NMMO outflow to this bath. The diffusion coefficient of water going to the cellulose solution is about 10 times larger than the ...

Phase diagram of the ternary system NMMO/water/cellulose
Cellulose, 2009The phase diagram of the system N-methylmorpholine-N-oxide(NMMO)/H2O/cellulose has been measured at 80 °C by establishing a solubility map (observation of the mixtures under the microscope), by the analysis of coexisting phases and determining the critical point.

Ethanol and biogas production from birch by NMMO pretreatment
Biomass and Bioenergy, 2013Abstract Birch wood was pretreated with N-methylmorpholine-N-oxide (NMMO or NMO) followed by enzymatic hydrolysis and fermentation to ethanol or digestion to biogas. The pretreatments were carried out with NMMO ( w NMMO = 85%) at 130 °C for 3 h, and the effects of drying after the pretreatment were investigated.

Structure formation of regenerated cellulose materials from NMMO-solutions
Progress in Polymer Science, 2001Cellulose as the most abundant regrowing organic material exhibits outstanding properties and useful applications, but also a tremendous challenge with regard to an economical and environmentally friendly chemical processing. In recent years the N-methylmorpholine-N-oxide (NMMO)-technology turned out to be a simple physical alternative to the yet ...

Biogas Production from N-Methylmorpholine-N-oxide (NMMO) Pretreated Forest Residues
Applied Biochemistry and Biotechnology, 2014Lignocellulosic biomass represents a great potential for biogas production. However, a suitable pretreatment is needed to improve their digestibility. This study investigates the effects of an organic solvent, N-Methylmorpholine-N-oxide (NMMO) at temperatures of 120 and 90 °C, NMMO concentrations of 75 and 85% and treatment times of 3 and 15 h on the ...
