Abstract
Hydrolyzing finely divided, solid Group IVB metal chlorides by gradually introducing the finely divided solids into the mixing zone of a high intensity mixer operating on an aqueous solution produces solid Group IVB metal oxy salts such as ZrOCl.sub.2.8H.sub.2 O.
Claims18
A process for hydrolyzing a Group IVB metal chloride to produce a metal oxy salt having a hydration number no greater than 6 in the course of the hydrolysis, comprising the steps of:
- continuously introducing Group IVB metal chloride solids into the mixing zone of a mixer;
- mixing 6 moles or less of water per mole of the Group IVB metal chloride solids water with the solids in the mixer having mixing blades, with said mixing blades rotating at a tip speed of at least about 20 feet per second to produce in the mixer a flowable granular hydrolyzed Group IVB metal oxy salt having a hydration number of no greater than 6;
- and
- flowing the Group IVB metal oxy salt having a hydration number of no greater than 6 from the mixer.
A process of hydrolyzing zirconium tetrachloride to produce a substantially free flowing, finely divided, solid zirconium oxychloride reaction product comprising reacting finely divided, solid zirconium tetrachloride with 6 moles or less of water per mole of zirconium tetrachloride, the water introduced as an aqueous solution of zirconium oxychloride, by continuously introducing said zirconium tetrachloride solids into the mixing zone of a mixer having mixing blades while rotating said mixing blades in the mixing zone at a tip speed of at least about 20 feet per second during operation of said mixer on said aqueous solution to agitate such solution within said mixing zone for producing in the mixer a zirconium oxychloride reaction product having a hydration number of from 4 to 6;
- and then flowing said reaction product from the mixer.
A process for hydrolyzing a Group IVB metal chloride, comprising the steps of:
- introducing Group IVB metal chloride solids into the mixing zone of a mixer having mixing blades;
- rotating mixing blades in the mixer at a tip speed of at least about 20 feet per second;
- mixing 6 moles or less of water per mole of Group IVB metal chloride with the solids in the mixer to produce in the mixer a flowable solid partially hydrolyzed Group IVB metal oxy salt;
- transporting the partially hydrolyzed solids from the mixer;
- trimming the moisture content of a first portion of the partially hydrolyzed solids as they are transported from the mixer;
- and
- blending a second portion of the partially bydrolyzed solids from the mixer into the moisture-trimmed solids.
