The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
MTBE forms azeotropes with water (52.6 °C; 96.5% MTBE) [23] and methanol (51.3 °C; 68.6% MTBE). [24] The solubility of water in MTBE is reported to be 1.5 g/100g at 23 °C. [23] In an investigational medical procedure called contact dissolution therapy, MTBE is injected directly into the gallbladder to dissolve cholesterol gallstones.
Molar mass: 46.069 g·mol −1 ... Dimethyl ether was first synthesised by Jean-Baptiste Dumas and Eugene Péligot in 1835 by distillation of methanol and ...
Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
Deuterated methanol (CD 3 OD), is a form (called an isotopologue) of methanol (CH 3 OH) in which the hydrogen atoms ("H") are replaced with deuterium (heavy hydrogen) isotope ("D"). [1] Deuterated methanol is a common solvent used in NMR spectroscopy .
Trimethylamine is prepared by the reaction of ammonia and methanol employing a catalyst: [5] 3 CH 3 OH + NH 3 → (CH 3) 3 N + 3 H 2 O. This reaction coproduces the other methylamines, dimethylamine (CH 3) 2 NH and methylamine CH 3 NH 2. Trimethylammonium chloride has been prepared by a reaction of ammonium chloride and paraformaldehyde: [9]
