Process of Deodorizing Petroleum and other Hydrocarbons.
I, ALBERT JOANNES TEMPÈRE, of 168, Rue St. Antoine, Paris, France,
Chemist-Micrographer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a process of treating certain hydrocarbons and
particularly petroleum, for the purpose of depriving them of their characteristic
disagreeable odor.
Refining even in the most perfect manner is inadequate to produce this result
and the attempts to attain it by means of perfumes have also failed to give any
practical result either industrially or commercially.
The process of my invention permits of obtaining a product possessing all the
properties of petroleum without its objectionable qualities.
This process is based on the employment of amyl acetate (amylacetic ether) of
which the moderate price, the agreeable odor, the uninflammability, and high
boiling point, render the product practically superior.
I will indicate as an example the addition of amyl acetate to petroleum,
preferably in the proportion of about ten grammes per litre, according to the
quality of the liquids employed.
'
I thus obtain a novel product giving a flame as pure as that produced by the
best petroleum.
The product possesses an agreeable, slightly-acidulated, odor and its combustion
does not give off any objectionable emanations.
In the preparation of my new product I may substitute, for the amylacetic ether,
any other acid or substance capable of producing the results above indicated as
constituting the special properties of the product.
Dated this 2nd day of June 1904

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to a process of treating certain hydrocarbons and

Refining, even in the most perfect manner, is inadequate to produce this result
and the attempts to attain it by means of perfumes have also failed to give any

Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The herein described process of treating petroleum, for the purpose of
deodorizing the same, which consists in adding amyl acetate, or its equivalent,
thereto, substantially in the proportions indicated.
2. As a new product, deodorized petroleum, suitable for lighting and heating
purposes, being a mixture of petroleum and amyl acetate, or its equivalent, as
specified.
