Benzylamine, also known as phenylmethylamine, is an organic chemical compound with the condensed structural formula C 6 H 5 CH 2 NH 2 (sometimes abbreviated as PhCH 2 NH 2 or BnNH 2).It consists of a benzyl group, C 6 H 5 CH 2, attached to an amine functional group, NH 2.
N,N-Dimethyl-1-phenylmethanamine. Other names N,N-Dimethylbenzenemethanamine, ... Density: 0.91 g/cm 3 at 20 °C Melting point: −75 °C (−103 °F; 198 K)
1-Phenylethylamine may be prepared by the reductive amination of acetophenone: [1]. C 6 H 5 C(O)CH 3 + NH 3 + H 2 → C 6 H 5 CH(NH 2)CH 3 + H 2 O. The Leuckart reaction, using ammonium formate, is another method for this transformation.

Its density is 0.964 g/ml and its boiling point is 195 °C. [10] Upon exposure to air, it combines with carbon dioxide to form a solid carbonate salt . [ 20 ] Phenethylamine is strongly basic , pK b = 4.17 (or pK a = 9.83), as measured using the HCl salt, and forms a stable crystalline hydrochloride salt with a melting point of 217 °C.
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4]. C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5]
Currently, Canada produces around 10% of cars sold in the US (approximately 225,000 units), with Mexico supplying close to 20%. Interestingly, the US actually produces more cars for Canadian ...
Air is given a vapour density of one. For this use, air has a molecular weight of 28.97 atomic mass units, and all other gas and vapour molecular weights are divided by this number to derive their vapour density. [2] For example, acetone has a vapour density of 2 [3] in relation to air. That means acetone vapour is twice as heavy as air.
