ABSTRACT:
A process for disproportionating rosins using iodide catalysts. In one embodiment, a tall oil rosin is heated in the presence of a lithium iodide catalyst. In another embodiment, a catalyst system is formed from a mixture of lithium iodide and ferrous iodide. The mixed catalyst system completes disproportionation of tall oil rosin in about three hours. Phosphoric acid may be added to remove iron colored impurities when using the mixed catalyst system. Another aspect of the invention involves preparing a soap from the disproportionated rosin by adding a defoamer and a base, such as potassium hydroxide.
