PLEASE Phenol production can be achieved using several reaction routes as a basis. In Five ways in which phenol can be produced from different raw Materials. I. Sulfonation process: benzene reacts with sulfuric acid to form benzenesulfonic acid. 66 + 24 65 3 + 2 At drastic conditions of molten sodium hydroxide (above 300 C), the acid produced is converted into sodium phenolic oxide. This melt is treated with water and filter the sodium sulfite. 65 3 + 3 65 + 2 3 + 20

Under acidic conditions, sodium phenolic oxide is converted to phenol. 65 + 2 + 2 65 + 3 II. Chlorobenzene process. In a sodium hydroxide solution at 5000 psi and 350C, the Chlorobenzene is converted to sodium phenolic oxide. 65 + 2 65 + + 2 The oxide is acidified to form phenol. 65 + 65 + III. catalytic process. In the vapor phase at 200 C, benzene reacts catalytically with acid. hydrochloric acid to produce chlorobenzene. 66 + + 1/22 65 + 2 Chlorobenzene is converted to phenol in a vapor phase reaction at 500 C and using a C/Cu-Fe catalyst.

65 + 2 65 +

IV. Toluene oxidation process. Using cobalt salts as a catalyst, toluene can be partially oxidized to benzoic acid as an intermediate, which in the presence of copper and magnesium salt catalysts can be oxidized to produce phenol and dioxide carbon. 65 3 + 2 65 + 2 65 + 2 65 + 2

V. Process based on cumene. This process begins with the vapor phase oxidation of cumene to produce cumene hydroperoxide, followed by an acidification reaction to form phenol and acetone. 65 37 + 2 65 362 65 362 65 + 36 Select a synthesis route and comment which Green Chemistry principles you consider to be could be implemented if a process was performed based on that path and what would be required to it.
