Description

Patented Mar, 15, 1938 UNITD MANUFACTURE or strain P No Drag. Application February Ill, 1936, Serial No. 63,278
@ @laims.
Paraflin as ordinarily refined, if subjected very much to heat deteriorates and becomes discolored. Particularly for example, where a paramn bath has to be maintained in which the paramn is heated as in the paraifining of paper and other articles to be water proofed etc., such dimculties are encountered. In accordance with the present invention however, it now becomes possible to prepare paraffin obviating such drawbacks.
To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims,'the following description setting forth in detail certain illustrative embodiments of the invention,'these beingindicative however, of but a few of the various ways in which the principle of the invention may be employed.
The parafiin, obtained from any usual or desired source, as for instance paraffin-bearing petroleum oil, is decolorized, as by treatment with sulphuric acid, sulphur dioxide, etc., and while in molten condition there is incorporated a small amount of a tetrahydroxybicyclospiroindane, as for instance 3,3,3,3 tetramethyl 5,6,5',6 tetrahydroxybicyclospiroindane, etc. The amount of such treating agent is in general small. It need not exceed 1 per cent. Amounts of 0,001 to 0.5 per, cent are satisfactory.
As an example: Paramn in molten condition is treated by incorporation of 0.01 per cent of 3,3,3',3' tetramethyl 5,6,5,6' tetrahydroxybicyclospiroindane,
10 1130 \CHS and the paraffin after thorough stirring, is cooled and. solidified in cake or other desired form.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent of such, be employed.
We therefore particularly point out and dis tinctly claim as our invention:-
