METHOD OF PREPARING ALCOHOL SOLVATE OF NEODYMIUM CHLORIDE Russian patent published in 2004 - IPC

Abstract RU 2220909 C2

FIELD: polymerization catalysts. SUBSTANCE: alcohol solvate of neodymium chloride useful as component for preparing diene polymerization catalyst is prepared by mixing aqueous solution of neodymium chloride with monoatomic aliphatic alcohol (butanol), after which azeotropic mixture butanol-water is distilled off at reduced pressure. Anhydrous butanol solution of neodymium chloride is fourfold diluted with isopropyl alcohol. Excess alcohol is distilled off in presence of liquid paraffin with boiling point 220-270 C on rotary film evaporator to form dispersion of alcohol solvate of neodymium chloride. EFFECT: optimized preparation procedure. 4 cl, 3 ex
