Synthesis of diphenylmethane (PhCH 2 Ph) from benzene and formalin (aqueous HCHO) was investigated in a biphasic reaction system, which consisted of benzene and aqueous phases, where the latter phase contains HCHO and liquid acid as catalyst. Sigma-Aldrich Products are sold exclusively through Sigma-Aldrich, Inc. When the benzene reacts with formaldehyde and hcl which compound is obtained? By continuing you agree to the use of cookies.

Synthesis of diphenylmethane (PhCH2Ph) from benzene and formalin (aqueous HCHO) was investigated in a biphasic reaction system, which consisted of benzene and aqueous phases, where the latter phase contains HCHO and liquid acid as catalyst. Chlorine is in excess and benzene is the limiting reactant. Since heteropolyacids exist in the aqueous phase exclusively, and the product diphenylmethane is concentrated in the benzene phase after the reaction, H3PW12O40 can be readily recovered from the reaction solution.

Still have questions? It’s hard for an ionic solution to mix with a strong non-polar solution. %. Get your answers by asking now. The conversion of HCHO and the yields of products of the reaction between the standard mixture of benzene (450 mmol) and aqueous HCHO (90 mmol) in the presence of H 3 PW 12 O 40 (4.2 mmol) at 140 °C and 160 °C are shown in Fig. The yields of diphenylmethane were proportional to the concentrations of both proton and the heteropoly anion (PW12O403−). Heteropolyacids such as H3PW12O40, H3PMo12O40, and H4SiW12O40 exhibited significant activities for the formation of diphenylmethane, whereas typical mineral acids (H2SO4, HNO3, and H3PO4), organic acids (para-toluenesulfonic acid (PTS) and CF3COOH), and Sc(CF3SO3)3 were inactive.
