    toluene‚ cyclohexene and naphthalene in hexene were subjected to parallel chemical testing to differentiate their intrinsic physical properties in terms of structure and behavior. The physical state and color were noted by simple physical observation. Nitration Testing was conducted for preliminary parallel testing until a positive result of yellow oil was seen. For the second and final testing‚ oxidation was done through introducing 3 drops of KMnO4 reagent and 2 drops of 10% NaOH solution to 5 drops of

    hydroxide. The resulting salt is mixed with solid sodium hydroxide and fused at a high temperature. The product of this reaction is sodium phenoxide‚ which is acidified with aqueous acid to yield phenol. Dow process In the Dow process‚ chlorobenzene is reacted with dilute sodium hydroxide at 300°C and 3000 psi pressure. The following figure illustrates the Dow process. Air oxidation of cumene The air oxidation of cumene (isopropyl benzene) leads to the production of both phenol

    Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide
