Processes for removing color bodies from guayule

A process for removing color bodies from an organic solution comprising guayule resin comprising

• a. providing an organic solvent-guayule resin stream comprising (i) at least 0.3 weight % guayule resin, based upon the total weight of the organic solvent-guayule resin stream, and either (ii) polar organic solvent in an amount of about 15 to about 80 weight % based upon the total weight of the organic solvent-guayule resin stream or (iii) polar organic solvent in an amount of about 45 to about 80 weight % based upon the total weight of the organic solvent-guayule resin stream, wherein the organic solvent-guayule resin stream includes no more than 1 weight % guayule rubber based upon the total weight of the organic solvent-guayule resin stream;
• b. contacting the organic solvent-guayule resin stream of (a) with activated carbon and producing a purified organic solvent-guayule resin solution and spent activated carbon;
• c. isolating the spent activated carbon from the purified organic solvent-guayule resin solution of (b);
• and
• d. contacting the isolated spent activated carbon from (c) with a regenerating solution comprising about 20 to about 50% by weight polar organic solvent and about 50 to about 80% non-polar organic solvent, thereby producing regenerated activated carbon.
