Production of Inodorous Coal Oil. — This process especially contem- 

 plates the treatment of refined oil, the object being to thoroughly remove all 

 traces of the original odor from the kerosene. 



To this end the invention consists in employing induced currents of air as a 

 vehicle for carrying away a portion of the odorous impurities in the liquid, and 

 of neutralizing or destroying a further portion of such impurities by the action of 

 sulphuric ether, and while changing the color of the product, in neutralizing the 

 remaining impurities by the addition of a coloring compound and a mixture for 

 imparting fragrance. 



In the procedure of carrying out the invention the kerosene is located in a 

 suitable tank where it is acted upon and thoroughly agitated for the period of 

 four hours, or thereabouts, by currents of ordinary atmosphere induced by any 

 suitable air-pumping apparatus connected to the said tank. 



When a certain quantity of sulphuric ether (about one drachm to each gal- 

 lon) is added to the product while in the tank, and thoroughly incorporated 

 therewith by the action of the air-currents which are again supplied as before 

 stated and continued for the period of about ten minutes. 



The color of the product so formed may now be manipulated to any desired 

 shade by adding to each fifty gallons a mixture consisting of one ounce of aniline 

 {any color) and twelve ounces of linseed oil. 



The addition of this coloring mixture not only changes the color of the pro- 

 duct but a portion of the remaining impurities are neutralized thereby. 



To still further and completely destroy any remaining trace of odorous im- 

 purity that may adhere to the product, and, at the same time to impart a pleas- 

 ing fragrance thereto, a mixture consisting of one ounce of oil of almonds {or any 

 other fragrant extract oil,) and one ounce of sulphuric ether is added to each fifty 

 gallons of product. 



The above described process has been patented by Mr. Leon Blumenthal, 

 of Kansas City.
