METHOD OF OBTAINING SOLVATE OF NEODYMIUM CHLORIDE WITH ISOPROPYL ALCOHOL FOR NEODYMIUM CATALYST OF ISOPRENE POLYMERISATION Russian patent published in 2014 - IPC C01F17/00 C08F4/44 B01J37/04

Abstract RU 2526981 C2

FIELD: chemistry.

SUBSTANCE: invention relates to petrochemical industry and can be used in production of neodymium 1.4-cis-polysoprene. Method of obtaining solvate of neodymium chloride with isopropyl alcohol for neodymium catalyst of isoprene polymerisation is realised by mixing neodymium chloride with isopropyl alcohol, with performance of hydrodynamic impact in tubular turbulent reactor of diffusor-confusor construction at the stage of synthesis of neodymium chloride solvate.

EFFECT: invention makes it possible to substantially reduce size of particles of obtained solvate suspension and ensures obtaining neodymium catalyst of high activity for isoprene polymerisation.
