Abstract
Processes are described for the recovery of natural rubber from solutions containing guayule rubber and resins. The resinous rubber is dissolved in a lipophilic solvent such as hexane. The rubber is recovered from the solution in high purity on a heated surface immersed in the solution.
Claims8
A process for recovering natural rubber from a lipophilic solvent by immersing a heated surface in the solution, whereupon the rubber precipitates and coagulates on the heated surface and can be thereby removed from the solution.
A process for recovering natural rubber from a lipophilic solvent wherein a heated surface separate from the solution vessel is immersed in the rubber solution and removed to recover the rubber aggregated on the dipped surface.
