Ethylamine like some other small primary amines is a good solvent for lithium metal, giving the ion [Li(amine) 4] + and the solvated electron. Such solutions are used for the reduction of unsaturated organic compounds , such as naphthalenes [ 11 ] and alkynes .
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
Ethylammonium nitrate or ethylamine nitrate [3] (EAN) is a salt with formula [CH 3 CH 2 NH 3] + [NO 3] −. It is an odorless and colorless to slightly yellowish liquid with a melting point of 12 °C. [4] This compound was described by Paul Walden in 1914, [5] [6] and is believed to be the earliest reported example of a room-temperature ionic ...
Methylamine has been produced industrially since the 1920s (originally by Commercial Solvents Corporation for dehairing of animal skins). [4] This was made possible by Kazimierz Smoleński [] and his wife Eugenia who discovered amination of alcohols, including methanol, on alumina or kaolin catalyst after WWI, filed two patent applications in 1919 [5] and published an article in 1921.
Melting point: −50 to −46 °C (−58 to −51 °F; 223 to 227 K) ... DIPEA can be used as a base in a number of transition metal catalyzed cross-coupling ...
where T m is the average melting point of the elements in the alloy. Ω should be greater than or equal to 1.0, (or 1.1 in practice), which means entropy dominates over enthalpy at the point of solidification, to promote solid solution development. [40] [41] Ω can be optimized by adjusting element composition.
