Selective Hydrogenation of Formamide to Methanol Over Supported Platinum Catalysts. [PDF]

Angew Chem Int Ed Engl
Amine–CO2 adducts can be hydrogenated to formamides and subsequently to methanol under mild conditions (<150°C), establishing an integrated CO2 capture‐and‐conversion route in a heterogeneous system that directly links amine sorbent cycling with methanol synthesis.

Crystallisation of cellulose/N-methylmorpholine-N-oxide hydrate solutions

Polymer, 2002
N-methylmorpholine-N-oxide (NMMO) hydrates are direct solvents for cellulose used commercially in the preparation of cellulose spinning dopes for fibre and film manufacturing. The fact that the cellulose/NMMO/water solutions can crystallise under cooling is important in the process of preparing fibres and films and in their structure formation.

Electromagnetic-Interference-Shielding Effectiveness of Lyocell-Based Carbon Fabrics Carbonized at Various Temperatures

Molecules, 2022
Lyocell is a biodegradable filament yarn obtained by directly dissolving cellulose in a mixture of N-methylmorpholine-N-oxide and a non-toxic solvent. Therefore, herein, lyocell fabrics were employed as eco-friendly carbon-precursor substitutes for use ...

Bioremediation of N-Methylmorpholine-N-Oxide: A Scientific Evaluation

, 2022
N-Methylmorpholine-N-Oxide (NMMO) – a bulk solvent for cellulose in industrial fiber making processes, has high cellulose dissolving capacity and lesser toxicity than CS2 which finds widespread use in the textile industry. In the NMMO process, more than 99% of the solvent is recycled within the process making the fabric eco-friendly.
