Definitions
- Crude organic materials may be purified by incorporating them into an organic matrix material in an amount in excess of normal compatibility under ambient conditions and thereafter causing the organic materials to exude from the organic matrix in purified form. Incorporation of the organic materials into the organic matrix materials is usually accomplished under elevated temperatures whereat both components are in a fluid state. Subsequent cooling of the blended materials results in the exudation of the purified organic material from the organic matrix.
- the method is particularly suitable for purifying various stabilizer compounds such as antioxidants, UV inhibitors, and the like, using polyolefins as the organic matrix material.
