  • Process to produce disproportionated rosin based emulsifier for emulsion polymerization
    Patent number: 6087318
    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.

  • Method for enriching rosin acids from a hardwood-containing sulfate soap
    Patent number: 5565134
    Abstract: The invention relates to a method for enriching rosin acids from a hardwood-containing sulfate soap, in which the soap is partially acidified at a temperature higher than room temperature with an inorganic or organic acid so as to give the resulting mother liquid a pH of 4.5-7, thus enabling the rosin acids to be enriched from the soap into the fraction converted to the acid form, and the fatty acids to be enriched in the soap.
