Caprolactam is a thermally unstable compound which on distillation may form methyl-, ethyl-, propyl-, and n-amylamines. Also, at high temperatures, CL reacts widi oxygen to form hydroperoxides which in the presence of iron or cobalt ions are converted into adipimide. /V-alkoxy compounds are also formed by the reaction of CL with aldehydes during storage.

Ethyl-3-methylpyridine (also known as aldehyde-collidine ) has been prepared by heating aldehyde-ammonia aldehyde-ammonia and acetaldehyde or paraldehyde aldol-ammonia and ammonia paraldehyde and ammonia <> 11,12 acetamide,1 or acetamide and phosphorus pentoxide ethylene glycol and ammonium chloride ethylidene chloride or bromide and ammonia ethylidene chloride and acetamide, ethylamine, or n-amylamine crotonic acid and a calcium chloride-ammonia complex 1 and by passage of acetylene or acetaldehyde and ammonia over alumina and other catalysts. 

The relative reaction rates of several amines with phenyl isocyanate in ether at 0°C have been determined. Aniline is about half as reactive as ethyl-, n-propyl-, n-butylamine, and n-amylamine is between eight and ten times as reactive as ammonia [28].

SYNTHESIS A solution of 33.2 g of veratraldehyde in 15.0 g nitroethane was treated with 0.9 g of n-amylamine and placed in a dark place at room temperature. In a day or so, separated H20 was apparent and, after a couple of weeks, the mixture completely solidified. The addition of 50 mL EtOH and heating effected complete solution and, on cooling, this provided 1 -(3,4-dimethoxyphenyl)-2-nitropropene as yellow crystals, 29.0 g, with nip of 70-71 °C. The more conventional reaction scheme, 6 h heating of a solution of the aldehyde and nitroethane in acetic acid with ammonium acetate as catalyst, gave a much inferior yield of product (33.2 g gave...

Matsunaga studied adsorption of n-amylamine on cleavage faces and edge sites of the crystals by the use of Auger spectrometry . He confirmed the easy adsorption and slow desorption on crystal edges, and the very slow adsorption and very easy desorption on cleavage faces. This behaviour is discussed later in relation to the effects of contaminants on friction.
