amine, on heating at 50''— 60° in a sealed lube, yielded 2.4.6-trini(i-o- 

 1.3-di-elliylaminobenzol, ni.p. 142°. 



On boiling with water is formed tlie 2.4.6-(rinitro-ethylnitramino- 

 phenol m.p. 105° described previously by Blanksma '). We tried to 

 substitute the alkylnitramino-group in this compound, and in the cor- 

 responding methyl derivative, by the ethyl-amino-group with the aid of 

 ethylamine. In this, however, we were till now not successful: the 

 OH-group appears to impede the substitution of the nitramino-group 



in this case.

Chemistry. ~ ''Contribution to the knowledcje of the amides." By 

 Prof. Franchimont. 



(Communicated in the meeting of September i27, 1913). 



Some years ago Dr. Moll van Chahante had already prepared a 

 substance which, on account of its mode of formation and the results 

 of the analysis, he pronounced to be the diamide of sulphonwobutyric 

 acid and which he has lately described under that name'). This sub- 

 stance which endures heating to a temperature over 300^ without 

 melting and which decomposes at d- 340^, does not i-eact with carbonyl- 

 chloride, not even at 300° and, as appeared afterwards, not even 

 with oxalylchloride. This strange behaviour, looking at the results 

 obtained by Bornwatek in the action of oxalylchloride on amides, 

 and also the fact that benzenesulphouamide does react with oxalyl- 

 chloride, although with formation of an oxalylderisative, induced 

 me to investigate the behaviour, in this respect, of the amides 

 of ^'t>butyric acid and ethanesulphonic acid which are more closely 

 connected with sulphon/^obutyric acid than the benzenesulpho- 

 namide. 



On adding wobiityramide to oxalylchloride in benzene a strong 

 evolution of heat took place immediately and a stream of hydrogen 

 chloride was evolved while a solid substance was being deposited. 

 After warming for a few hours, the evolution of gas ceased and 

 everything had again dissolved. The following day, after cooling, a
