The synthesized benzaldehyde‐based bisphenol was analyzed for its molecular structure by FTIR, 1 H NMR, and 13 C NMR spectroscopy. Benzaldehyde is an aromatic aldehyde. The Carcinogenic Potency Database (CPDB) is a unique and widely used international resource of the results of 6540 chronic, long-term animal cancer tests on 1547 chemicals. The alkene hydrogens, Ha, usually show up in the aromatic region of the spectrum, around 7. •benzaldehyde is commercially available in two grades. Some of the side products expected in this reaction could be: 1. In this way, the reaction. Phenylacetaldehyde can be obtained via various synthetic routes and precursors. 06 mole) in 500 mL of water until the formation of the addition compound was complete. After the completion of the reaction, the reaction mass was quenched with toluene to get a solid residue. Some representative aromatic compounds and their uses are listed in Table 13. Gatterman - Koch reaction is use for the preparation of benzaldehyde or substituted benzaldehyde by treating benzene or substituted benzene with carbon monoxide and hydrogen chloride in presence of anhydrous aluminum chloride or cuprous chloride. Benzaldehyde is described as being narcotic to man at high concentrations (Merck Index, 1968), and from a study of two cases, it was concluded that 50-60ml benzaldehyde taken by mouth would be followed by death in the absence of prompt treatment (Dadley, 1928).
