Reclaiming oil composition and method of making it

Claim 1

THE PROCESS OF PRODUCING LIQUID TALL OIL COMPOSITIONS FOR USE IN THE RECLAIMING OF RUBBER WHICH COMPRISES SUBJECTING CRUDE TALL OIL CONTAINING ROSIN CRYSTALS THEREIN TO PROLONGED HEATING WITH AGITATION AT ABOUT 130*C. FOR A SUFFICIENT PERIOD TO EFFECT A SUBSTANTIAL INCREASE IN THE VISCOSITY OF THE TALL OIL AND TO DISSOLVE THE ROSIN CRYSTALS IN THE TALL OIL AND FORM A CLEAR LIQUID PRODUCT, THEREAFTER INCORPORATING IN THE TALL OIL AT SUCH TEMPERATURE A SMALL AMOUNT OF A STABILIZING LIQUID SOLVENT TO STABILIZE THE COMPOSITION AGAINST PRECIPITATION OF SOLIDS THEREFROM AND CONTINUING THE HEATING AND AGITATION AT SUCH TEMPERATURE TO FORM A HOMOGENEOUS LIQUID PRODUCT, THE TOTAL PERIOD OF HEATING OF THE TALL OIL AT ABOUT 130* C. BEING FOR ABOUT 24 TO 50 HOURS, AND CONTINUING THE AGITATION AFTER THE HEATING IS DISCONTINUED AND DURING SLOW AND GRADUAL COOLING OF THE PRODUCT, THE PROPORTIONS OF STABILIZING LIQUID SOLVENT BEING BETWEEN ABOUT 3.5 AND 7.5 PARTS FOR 96.5 TO 92.5 PARTS OF TALL OIL, AND THE STABILIZING LIQUID BEING A LIQUID NON-VOLATILE AT THE TEMPERATURE OF HEATING SELECTED FROM THE CLASS WHICH CONSISTS OF LIQUID AROMATIC HYDROCARBON OILS, LIQUID NAPHTHENIC HYDROCARBON OILS, DIETHYLENE GLYCOL, AND MIXTURES THEREOF.
