Trans. N. V. Ac. Sci. 62 Jan. fc', 



January 8, 1883. 



Regular Business Meeting. 



Vice-President, Dr. B. N. Martin, in the Chair. 

 Twenty persons present. 



Mr. C. E. Colby was elected Resident Member, and the resig- 

 nation of Mr. E. Vansychel was accepted. 



It was " Resolved, that the Publication Committee be authorized 

 to prepare and pubhsh an appeal for additions to the General 

 Pubhcation Fund." 



Dr. Albert R. Leeds read a paper, illustrated by specimens, upon 

 five new organic compounds, viz: — cenantholaniline,. 

 cenantholxylidine, cenantholnaphthylamine, cryptidine, 



AND ACROLEINUREIDE. 



(Abstract). 



CEnanthol was prepared by fractional distillation at 150" of castor 

 oil in partial vacuo. It unites, with great energy and elevation of tem- 

 perature, with the aromatic bases, to form oils of closely related physi- 

 cal properties. 



Purification by distillation was found impracticable, as was also the 

 use of solvents, such as alcohol, benzol, chloroform and carbon disul- 

 phide. Finally the following plan proved successful. Each of the three 

 compounds was dissolved in i5ogrms. glacial acetic acid, heated for 

 some hours on the water-bath, and, after complete combination of the 

 excess of aromatic base, was converted into its respective acetic ac'd 

 salt. A large excess of water was added, which precipitated the 

 oenanthol compound, whilst the salt of the aromatic base remained 

 m solution. After complete washing with water and drying at 100" C, 

 the new compounds were submitted to analysis. 



Qinantholaniline, CgHiN, C,Hi40, is a reddish mobile oil of pleas- 

 ant etherial smell; so is cenantholxylidine, CsHuN, CvHuO. and 

 cenantholnaphthylamine, C10H9N, CtHiiO. In the last case, the 

 etherial smell is very pronounced and agreeable, resembling the odor 

 of pineapple. 



It is remarkable that these compounds, formed synthetically by the 

 direct union of a molecule of oenanthol with a molecule of the aromatic 

 base, without the elimination of molecule, should evolve so great heat 

 of combination. They are permanent compounds, and can be sublimed 

 with only partial decomposition. The sublimates are not crystalline.
