100 Dr. Kane on the Combinations derived from Pyroacetic Spirit. 



substances, and to prevent reiteration in the description of them, if a general 

 view of the results be now presented, and the names by which it is proposed to 

 designate these bodies be detailed. 



By the loss of successive portions of its oxygen and hydrogen in the form of 

 water, there are obtained from pyroacetic spirit substances having the composition 

 Cg H5 o and Cg h^. By reactions, to be described hereafter, there are produced 

 other bodies having the formulae Cg Hj cl and Cg h^ i. The body Cg H5 o unites with 

 acids, as the sulphuric and phosphoric, and forms compounds possessing acid 

 properties and forming well characterized salts, the exact composition of which 

 will be hereafter given : in all these reactions it is evident that the pyroacetic 

 spirit follows the same general law as the pyroxylic and the ordinary alcohol ; 

 and as there are two theoretical views of the nature of the ordinary ethers, so can 

 two views of the nature of these new bodies be assumed. But whilst I admit the 

 possibility of explaining, perhaps all known phenomena, by each hypothesis, yet 

 as I consider that of common ether, being oxide of ethyl, as most consonant with 

 the general bearing of science, I shall adopt in this paper the corresponding view 

 for the combinations I am about to describe. 



The names Acetone and Pyroacetic Spirit, having reference not to the nature, 

 but to one only of the many sources from whence this body can be obtained, it is 

 necessary to substitute for these a name which can be made the foundation of a 

 series, and not indicate any connexion with another substance, which, if real, is at 

 least but accidental. The name Mesit was applied by Reichenbach to a liquid 

 which he met among the products of destructive distillation, and which he took 

 to be pyroacetic spirit; and without at all judging whether that fluid was or was 

 not such, I shall adopt that denomination, and propose for the pyroacetic spirit 

 the name Mesltic Alcohol. We thus obtain 



Cg H4 mesitylene. 



Cg Hj o = CgH^ -\- HO mesitic ether ; first hydrate of mesitylene. 



Cg H5 cl = Cg H4 -|- Hc^ hydrochlorate of mesitylene. 



Cg H5 1 = Cg H4 4" HI hydriodate of mesitylene. 



Cg Hg 0^= Cg H4 -{- Hj O2 mesitic alcohol ; second hydrate of mesitylene. 



Cg H5 o -|- SO3 sulphate of mesitic ether. 



Cg H5 o -j- 2SO3 bi-sulphate of mesitic ether. 



Cg H5 o -J- Pj O5 phosphate of mesitic ether.
