06 EXAMINATION OF A NAPHTHA FROM LIME-SOAP. 



cally characterized by the presence of the olefiant series of hydro-carbons, that is, the 

 lower series of C n II n , A recent examination by A. Wurtz, 1 of the naphtha obtained 

 by distilling a mixture of amyl-alcohol and chloride of zinc, goes to show that in this case 

 the olefiant series is accompanied by that series of hydrides the several members of 

 which boil at 0°, 30°, 60°, 120°, and 150°. We have proposed to ourselves to re-examine 

 this naphtha from amyl-alcohol at an early day, for the purpose of proving whether or 

 no it contains also members of the other series of hydrides (Schorleminer's) which 

 boil at 8°, 38°, 68°, 98°, and 128°, as well as for the sake of obtaining the paramylene 

 compounds, which we desire to compare with some of the members of our higher series 

 of C n H n . 



As has been stated in the text above, the quantity of liquid contained in each of the 

 heaps was roughly measured. On summing up these several amounts it appeared that 

 there was altogether a total of nearly 6400 c. c. of liquid. Of this amount about 0.8% 

 consisted of amylene and hydride of .amyl. 



3.9% of Caproylene. 

 2.8% of Hydride of Caproyl. 

 3.1% of Benzole. 

 4.7% of (Enanthylene. 



« 



.6% of Hydrate of (Enanthyl. 

 6.9% of Toluole. 



1 2.5% of Caprylene and Hydride of Capryl. 

 13.3% of Xylole. 



7.8% of Pelargonene. 

 23.5% of Isocumole and Rutylene. 

 10.2% of Margarylene. 



3.1% of Lauiylene. 



With regard to this table, it must be understood that it refers only to the quantities 

 of liquid contained in the actual heaps, and does not'include the numerous small frac- 

 tions lying between the heaps. It is offered merely as an approximative indication of 

 the relative proportions in which the several hydro-carbons were obtained. In the pres- 

 ent condition of chemical science there can be of course no thought of attempting the 

 quantitative analysis of a crude naphtha like the one now under consideration. In- 

 deed, it has been to ourselves a matter of surprise and gratulation that we have been 

 able successfully to effect the qualitative separation of the hydro-carbons from a mix- 

 ture so extremely complex as this. The actual isolation of fifteen or sixteen different
