N-Methylmorpholine N-oxide (more correctly 4-methylmorpholine 4-oxide), NMO or NMMO is an organic compound.This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP. [1]
N-Methylmorpholine is the organic compound with the formula O(CH 2 CH 2) 2 NCH 3.It is a colorless liquid. It is a cyclic tertiary amine.It is used as a base catalyst for generation of polyurethanes and other reactions.
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
The lyocell process is the method of dissolving cellulose (cotton) in N-methylmorpholine N-oxide to form a solution that has hydrogen bonds (NMMO• H 2 O). [4] The solution is then spun in a water bath, resulting in pure, reusable cellulosic fibers. [4]
An autopsy later established that the body was that of a White man aged between 30 and 60 years old, about 6 feet (1.8 meters) tall, wearing a wetsuit, and had been in the water for up to 12 weeks.
Typical reagents include H 2 O 2 (Milas hydroxylation), N-methylmorpholine N-oxide (Upjohn dihydroxylation) and K 3 Fe(CN) 6 /water. These reoxidants do not react with the alkenes on their own. Other osmium compounds can be used as catalysts, including osmate(VI) salts ([OsO 2 (OH) 4)] 2−, and osmium trichloride hydrate (OsCl 3 ·xH 2 O ...
During testing, the Moccamaster aced what the ECBC calls the "four Ts" of coffee brewing: temperature, time, turbulence (even saturation), and total dissolved solids (a measure of coffee solubles ...
