Ethyl acardite

It is prepd by the action of methylamine on 4-chloro-l-nitrobenzene (Ref 5) by the action of methyl iodide (Ref 6), or methyl sulfate on 4-nit roaniline (Ref 7) or by the hydrolysis of 4-nitro-N-methylformanilide with hot coned aq HC1 (Ref 8). In a study of the effect of nitric acid concn on the prods of the nitration of N,N-dimethylaniline to form Tetryl, it was isolated in low yield by the action of nitric acid, d 1.046g/cc, plus Na nitrite on N,N-dimethylaniline (Ref 10). A eutectic mixt with N-ethyl-4-nitroaniline has been patented as a stabilizer for NC (Ref 12). Studies at NPF indicate that 4-nitro-N-methyl-aniline is superior to Centralite, 2-nitrodiphenyl-amine, or Acardite in stabilizing. NC Refs 1) Beil 12, 586, (295) 1125 ...

Acardite III or Ethylacardite (N -Ethyl-N,N-diphenylurea)(Akardit III, in GerX C, H, NH.CO.N(C H,, row 240.29, N 11.66%, OB to CO, -246.4%, OB to CO -146.5%. White cry St, rop 72.3° for a tech sample and 73.1° for samples recrytd from ethanol or chlf(Ref 4). It was prepd in Germany by treating with p>hosgene a soln in carbon tetrachloride of equimolar quantities of ethyl-amine and diphenylamine in the presence of limestone. This was followed by fractional distillation. The following reaction took place ...
