Abstract
1518058 Titanium trichloride SOLVAY & CIE 11 Oct 1976 [15 Oct 1975] 42129/76 Heading C1A [Also in Division C3] Particles of TiCl 3 associated with a liquid other than water are dried to a liquid content less than 1% by weight, preferably less than 0À3%, the particles being of substantially spherical shape and comprising an agglomerate of smaller particles which are spherical and porous. The liquid associated with the particles may be an aliphatic, cyclo aliphatic or aromatic hydrocarbon, TiCl 4 , Lewis acid or Lewis base used to treat the trichloride. The starting material preferably contains at least 5% of the liquid. Drying is preferably carried out at below 90‹C for 0À2-48 hours at atmospheric or reduced pressure. Drying may be performed under a stream of inert gas in any appropriate apparatus but preferably in a fluidized bed. The spheres suitably have a diameter of 5-100 microns and the diameter of the smaller particles is typically 0À05-1 micron. Such particles suitably have a composition of TiCl 3 .(AlRCl 2 ) x .C y where R is 2-6 C alkyl, C is a complexing agent comprising one or more organic compounds which contain at least one atom or group possessing at least one electron pair capable of forming a coordination bond with Ti and Al; x is less than 0À2 and y is greater than 0À009. Such particles typically have an apparent specific gravity of 0À6-1À2 kg/dm<SP>3</SP>, a surface area greater than 75 m<SP>2</SP>/g and an internal pore volume greater than 0À15 cm<SP>3</SP>/g.
