On the Classification of Carlton-Compounds.

compounds, owing to the splitting off of ammonia in various 
operations. A large number of specific observations might be 
enumerated by way of illustration; a few, however, may suffice. 
1. The formation of polymethylene imines from the corres¬ 
ponding diamines: e. g. 
CH 3 .CHCH 3 NH 3 CH 3 .CHCH 2 .

2. The quantitative decomposition of some salts of bases into 
ammonium chloride and less saturated hydro-carbons, e. g.: 
C 10 H 15 NH 2 HC1 = NH 4 Cl-bC 10 H 14 
Pinylamine hydro- Cymene 
chlorate. [Ber. 24, 3084]. 
C 10 H 17 NH 2 HC1 = nh 4 ci-i-c 10 h 16 
Dihydrocarvylamine Terpinene 
hydrochlorate. [Ber. 24, 3985]. 
3. If several or all of the valencies of the nitrogen atom are sat¬ 
urated by radicles, substituted ammonias frequently split off 
with equal readiness. Attention may be called to Hofmann’s 
method for the “ Abbau ” of piperidine bases. [Ber. 16, 2068, 
and 19, 2628].

Not only can ammonia or its substitution products be split 
off readily from more complicated nitrogen derivatives, analo¬ 
gous to the dehydration of hydroxy derivatives, but, like water, 
it can often be added with similar readiness. A few examples 
will suffice to illustrate these syntheses of nitrogen compounds:
