METHOD OF OBTAINING COMPLEXES OF TRICRESYL-, TRI(1,3-DICHLOROPROPYL)- AND TRI(2-ETHYLHEXYL)PHOSPHATES WITH Sn AND Ti CHLORIDES Russian patent published in 2009 - IPC C07F9/00 C07F7/22 C07F7/28

Abstract RU 2347785 C1

FIELD: chemistry.

SUBSTANCE: present invention pertains to the method of obtaining complexes of tricresyl-, tri(1,3-dichloropropyl) and tri(2-ethylhexyl)phosphates with Sn and Ti chlorides, with general formula 2(RO)₃P=O•"Э"Cl₄, where R=-C₄H₆CH₃, -CH(Cl)CH₂CH₂(Cl) or -CH₂CH(C₂H₅)(CH₂)₃CH₃, "Э" = Sn, Ti, and can be used in organic synthesis. The method is characterised by that, it involves reaction of tricresyl-, tri(1,3-dichloropropyl)- or tri(2-ethylhexyl)phosphate with Sn and Ti tetrachlorides at room temperature and molar ratio of phosphate : tetrachloride 2:1.

EFFECT: design of an effective method of obtaining complexes.
