WebThen ethene reacts with basic KMnO 4. It gives diol compound (HO-CH 2-CH 2-OH). Then it is heated with concentrated H 2 SO 4 to get acetylene. How to prepare benzene from phenol and acetylene. We have already discussed the acetylene to benzene conversion. From phenol. When phenol is distilled with zinc dust, it gives benzene. More Organic ... WebEthylene formation rates were 20 times faster over a PtSn(1:3)/H-ZSM-5 catalyst with SiO2:A1203 = 280 in comparison to those over PtSn(3:1)/SiO2. H-ZSM-5-supported catalysts were also active for the formation of aromatics, and the rates of benzene and naphthalene formation were increased by using more acidic H-ZSM-5 supports.
