ITED STATESA GUSTAV EGLOFF AND HARRY I. BENNER, OF CHICAGO, IIILIN'OIS, 'ASSIGNORS TO 'UNI- VERSAL OIL PRODUCTS COMIPANY, OF CHICAGO, ILLINOIS, A CORPORATION F SOUTH DAKOTA PROCESS OF CRACKING ROSIN Application 4filed December 20, 1920, Serial No. 432,070. Renewed March 15, 19.28.
Among the salient objects of our invention are to provide a process of converting resinous material such as rosin from the destructive distillation of wood in the presence of water or steam to produce light oils therefrom, as
conversion products resulting from heat and.
' to provide a cracking process of converting resinous material and water to produce light oils therefrom, exerting a vapor pressure on the system in excess of 5000 pounds to the square inch; to provide a cracking process to produce an oily material lighter than 15 degrees Baume and containing an unsaturated hydrocarbon content of 10% or more; and in general to provide improved products and process of making same.
An apparatus suitable for carrying out the Ainvention is disclosed in the drawing, in which the single figure is a side elevation of the apparatus with parts shown in section.
The apparatus comprises a shell still 1 constructed to withstand' high pressures, which still is mounted above the heating chamber 2 of a suitable furnace. vided with a combustion chamber 3, in which are positioned va plurality of baffles 4:. The furnace is heated through the medium of the burners 5, which discharge into the combustion chamber 3. A ue 6 leads the products .of combustion from the heating chamber 2.
The still 1 is provided with a vapor outlet 7, controlled by a suitably constructed valve 8.
If desired, the still may be provided with a pressure gage 9, as well as with a pyrometer 10. rllhe still is preferably provided with a removable manhole cover 11, as well as`with a draw-olf line 12 controlled by a suitable valve 13. g
A typical run of this process is as follows:
The high pressure stilll is charged with` resinous material such as rosin 90% by weight, and 10% by weight of water and said high pressure still is heated until a maximum pressure of 5600 pounds was obtained and a temperature of 910 degrees F. in the liquid.
The following table discloses the operating The furnace is proconditions under which the process is carried out:

It 1s to be noted that the maximum liquid temperature was 910 F. and that at this temperature the' pressure was 5600 pounds. No substantial decomposition occurred before the .temperature reached 650o F. and the pressure reached substantially 1200 pounds per B. Gr. 15.7. Unsaturates 14%.

It is to be noted that the oil recovered from the rosin and Water when treated under .ourj
4process had a gravity of 15.7 o Baum., an initial boiling point of 118 F., and that 90% only 8% loss from tar bottoms.
The 'product recovered possesses drying characteristics of the character of turpentine. It constitutes a lightoil and is suitable for use as a drying agent in paints and various compositionswhere a drying oil is required.
We claim as our invention:
1. A process of Vcra/cking rosin in the presence` of Water, which` consists in introducing said mixture to a still, in subjecting the mixture to heat and pressure suicient t0 raise its temperature above 900o F. and to generate a vapor pressure exceeding 5000 pounds per square inch to convert a substantial portion of the mixture into a light oily product.
2. A process. of cracking rosin in the presence of Water, which comprises introducing the mixture into a still, in raising the temperature thereof in excess of 7 00O F. and in generating a Vapor pressure on the mixture in excess of 1000 pounds per square inch to convert a substantial portion of the solid constituents of the mixture into a light oily product.
3. A process of cracking rosin in the presence of water, which conslsts in introducing the rosin andlwater into a still and heating the same to a temperature in excess of 700 F. and under a vapor pressure in excess of 1000 pounds per square inch to convert more than 20% of the solid material into oily constituents lighter than 30 degrees Baum.
