In Schaedler's Technologie der Erdole x another analysis of 

 Burmese oil is given, and the name of the analyst as H. Vohl. 



The Rangoon oil 2 is here described as follows: "Farbe, griinlich 

 braun ; Geruch, eigenartig, nicht unangenehm j Consisteur, von 

 Gansefett ; spec. gevv. 0*885 — 0*890." 



It contains : —

In 1865 Messrs. Warren and Storer s examined some samples of 

 petroleum from Burma which they describe as follows : — 



" Upon examination the petroleum was found to be a thick, greasy matter, 

 not sufficiently liquid to admit of being poured from the can which contained it 

 when the temperature of the air was 25°C, but upon being heated, it flowed readily 

 at 30°— 33 , and became perfectly fluid at 3S — 40° The color of the mass was 

 yellowish green. It emitted the odor common to the purer varieties of native 

 petroleum ; though the odor was but slight and in nowise offensive. The specific 

 gravity of this native petroleum was o 1 875 at 29 ." 



When distilled and heated up to 3oo°C, 30-46 per cent, of volatile 

 product, or naphtha as it is called, were obtained. This naphtha was 

 further examined and contained : 



Rutylene, distilling from 170° to 176 

 ? „ „ i8o = to 184 



Margarylene ,, ,, 186° to 193° 



Laurylene „ ,, 200° to 214° 



Cocinylene „ „ 226 to 234 



Naphthaline. 

 It probably also contains Pelargone C l3 H l8 boiling at about 155°.
