Benzyl alcohol butane

The solids analysis described above can be taken to yet another level by correlating the color measurement to chemical properties. An excellent model system is vanadium pyrophosphate (VPO), which is a well-known catalyst for butane oxidation to maleic anhydride. During the synthesis of the catalyst precursor, solid V2O5 particles are dispersed in a mixture of benzyl alcohol and i-butanol. In this slurry phase, the vanadium is partly reduced. Addition of phosphoric acid leads to a further reduction and the formation of the VPO structure. With a diffuse reflectance (DR) UV-vis probe by Fiberguide Ind., the surface of the suspended solid particles could be monitored during this slurry reaction. Four points can be noted from Figure 4.4 ...

Because the strongly basic media is often hostile to the carbonyl compound produced in these transformations, it has not been characterized in all of our studies. The fate of the carbonyl compound, however, is not unimportant to the nature of the transformation. The fragmentation of Vc produces benzaldehyde which subsequently disproportionates by the Cannizaro reaction to give benzyl alcohol and benzoate (4). This process consumes base and requires the nitrosamine cleavage reaction to be run with a near-stoichiometric quantity of base. The study of the carbonyl compounds produced in the fragmentation of Vb demonstrated that the initially produced butanal entered into several expected and unex-...

Panthenol and pantothenic acid have been identified and quantified in pharmaceutical preparations by extraction with ethanol or benzyl alcohol, separation by TLC on silica gel and the chromatogram developed in propan-2-ol-water (85 15). Spots were measured by spectrodensitometry (13). The overpressure derivatization technique has also been applied following separation of calcium pantothenate from other hydrophilic vitamins on silica gel HPTLC layers developed in butan-l-ol-pyridine-water (50 35 15) (11).
