Benzaldehydes benzene

A number of recommendations have been made in the development of quantitative chromatographic methods. The American Society for Testing Materials — using as a benchmark the reversed phase separation of benzyl alcohol, acetophenone, benzaldehyde, benzene, and dimethylterephthalate — discovered substantial laboratory-to-laboratory differences in quantitative analysis.53 These compounds are routinely used to test column performance or for system suitability testing. A followup study, using benzyl alcohol, acetophenone, p-tolualdehyde, and anisole, showed that measurement of... 

Thermal decomposition of RhH(CO)(PPh3)3, the well known hydroformylation catalyst, in the absence of H2 and CO leads to a stable cluster shown in Figure 2.36 containing p2-PPh2 fragments [31], Under hydroformylation conditions also other products are found such as benzaldehyde, benzene, and diphenylpropylphosphine.

Triphenylmethane has hitherto usually been prepared by the interaction of benzene and chloroform in the presence of aluminium chloride 5 or ferric chloride,2 but the yields are considerably lower. Other methods consist in the action of benzal chloride upon benzene and aluminium chloride,6 in heating benzal chloride and mercury diphenyl,7 and in heating a mixture of benzaldehyde, benzene, and zinc chloride.8...

Ignites on contact with alcohols, acetic anhydride + tetrahydronaphthalene, acetone, butanol, chromium(II) sulfide, cyclohexanol, dimethyl formamide, ethanol, ethylene glycol, methanol, 2-propanol, pyridine. Violent reaction with acetic anhydride + 3-methylphenol (above 75°C), acetylene, bromine pentafluoride, glycerol, hexamethylphosphoramide, peroxyformic acid, selenium, sodium amide. Incandescent reaction with alkali metals (e.g., sodium, potassium), ammonia, arsenic, butyric acid (above 100°C), chlorine trifluoride, hydrogen sulfide + heat, sodium + heat, and sulfur. Incompatible with N,N-dimethylformamide. 

Under the reaction conditions used, a U3O8 catalyst demonstrated appreciable selective oxidation activity. The best results, in terms of both activity and selectivity to benzaldehyde, were obtained with the mixed oxides with U Mo atomic ratios in the range 8 2 to 9 1. The maximum yield of benzaldehyde was 40 mol%. On the other hand, antimony-based uranium oxides were not found to be effective as catalyst for this reaction. U—Mo and Bi—Mo mixtures also exhibited promising activity and selectivity to benzaldehyde. Bi—Mo and Bi—Mo—P—Si catalysts were also tested. Qualitahvely there was little difference between the product distributions from the two catalysts. The major products formed were benzaldehyde, benzene and carbon oxides, as well as traces of anthraquinone and benzoic acid.
