摘要： In the present invention, tall oil acids are prepared by acidulating tall oil soap with supercritical fluid carbon dioxide. The method of preparation is carried out at a temperature of from about 31.degree. to 400.degree. C. and the supercritical carbon dioxide is under a pressure of from about 1075 to about 50,000 psi. The acidulate is extracted into the fluid phase of the supercritical carbon dioxide. The resultant tall oil acids are then recovered from the carbon dioxide fluid phase.

摘要： A process is disclosed for coating particles comprising suspending the particles in a fluidized bed and introducing therein an encapsulating latex. During introduction of the latex, the fluid bed must be maintained at a temperature which is within 10.degree. C. lower to 20.degree. C. higher than the glass transition temperature of the polymer. Typical core materials include halogen and peroxygen bleaches, bleach precursors, enzymes, colorants and fabric softeners. Preferably, the latex comprises water as a carrier and a polymer with carboxyl functionality, the polymer being insoluble in water.
