Titanium 111 sulfate

Titanium Sulfates. Solutions of titanous sulfate [10343-61-0] ate readily made by reduction of titanium(IV) sulfate ia sulfuric acid solutioa by electrolytic or chemical means, eg, by reduction with ziac, ziac amalgam, or chromium (IT) chloride. The reaction is the basis of the most used titrimetric procedure for the determination of titanium. Titanous sulfate solutions are violet and, unless protected, can slowly oxidize ia coatact with the atmosphere. If all the titanium has been reduced to the trivalent form and the solution is then evaporated, crystals of an acid sulfate 3 Ti2(S0 2 [10343-61-0] ate produced. This purple salt, stable ia air at aormal temperatures, dissolves ia water to give a stable violet solutioa. Whea heated ia air, it decomposes to Ti02, water, sulfuric acid, and sulfur dioxide. 

Dicarboxyhc acids, eg, succinic or adipic, do not dissolve titanic acid. A phthalate has been prepared by adding acidic titanium sulfate solution to sodium phthalate solution. 

First, it is important to note that complete fluorination of the elements ensures an effective separation process. Particularly, Maiorov and Nikolaev [477] developed and reported on the conversion of tantalum, niobium and titanium sulfates and chlorides into their respective fluorides. It was shown that such conversion leads to significant improvement in/enhancement of the separation of the elements.

Acid Solution. Acetone and hydrogen peroxide are the principal oxidation products observed in the radiolysis of 2-propanol in sulfuric acid solution. Identical results were obtained for hydrogen peroxide estimation by both the titanium sulfate and iodide ion estimations, indicating that organic hydroperoxides were not formed or that, if formed, they rapidly decompose to acetone and hydrogen peroxide. The yields obtained are summarized in Table I. In all cases, it was clearly established that product yields were independent of dose initially. 

The hydrolysis of concentrated solutions of titanium sulfate (170-230 g Ti02/L) proceeds very sluggishly and incompletely (even if boiled) unless suitable nuclei are added or formed to accelerate hydrolysis. The nuclei are usually produced by two methods. In the Mecklenburg method, colloidal titanium oxide hydrate is precipitated with sodium hydroxide at 100°C 1% of this hydrate is sufficient. In the Blumenfeld method a small part of the sulfate solution is hydrolyzed in boiling water and then added to the bulk solution [2.31]. The particle size of the hydrolysate depends on the number of nuclei. 

The titanium sulfate concentration has a great influence on the flocculation of the hydrolysate. It is adjusted, if necessary by vacuum evaporation, to give a Ti02 content of 170-230 g/L during hydrolysis. Lower concentrations result in a coarser particle size. 

Direct chemical reduction of titanium oxide, titanium chloride, titanium sulfate, or titanium hydride with carbon, nitrogen, or ammonia or by both carbon and nitrogen to form TiC, TiN and TiCN.3-6 Titanium nitride can also be prepared in a plasma jet from titanium tetrachloride and nitrogen.7...

The technological aspects of hydrous titanium oxide production were developed in Great Britain. This product is obtained in irregular granular form by precipitation with basic titanium sulfate or chloride solutions. After the precipitation step further granulation of the precipitate is obtained using different methods. A typical product composition is 60% Ti02, 30% HjO, and 10% a mixture of other components, includ-...

Derivation From hydrochloric acid solution of tita-nates by treating with ammonia and then drying over concentrated sulfuric acid or by boiling titanium sulfate solution. 

Derivation From ilmenite or rutile. (1) Ilmenite is treated with sulfuric acid and the titanium sulfate further processed. The product is primarily the anatase form. (2) Rutile is chlorinated and the titanium tetrachloride converted to the rutile form by vapor-phase oxidation. Papermakers are using this form to an increasing extent in preference to the anatase form. 

Preparation of new solid super-acid catalyst, titanium sulfate supported on zirconia and its acid catalytic properties... 

Titanium sulfate supported on zirconia catalysts were prepared by drying of powdered Zr(OH)4 with titanium sulfate aqueous solution followed by calcining in air at high temperature. The characterization of prepared catalysts was performed using Fourier transform infrared (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and by the measurement of surface area. The addition of titanium sulfate to zirconia shifted the phase transition of ZrOa from amorphous to tetragonal to higher temperature because of the interaction between titanium sulfate and zirconia. The catalytic activities for both reactions, 2-propanol dehydration and cumene dealkylation were correlated with the acidity of catalysts measured by ammonia chemisorption method.
