Question

Từ C, CaCO₃ và các chất khác. Viết pt điều chế etanol, fomanđehit, ortho-cresol.

Answer 1

\(C+2H_2\xrightarrow[t^\circ]{Ni}CH_4\)

\(2CH_4\xrightarrow[lln]{1500^\circ C}C_2H_2+3H_2\)

\(C_2H_2+H_2\xrightarrow[t^\circ]{Pd\text{ / }PbCO_3}C_2H_4\)

* \(C_2H_4+H_2O\xrightarrow[t^\circ]{H_2SO_4\left(\text{đặc}\right)}C_2H_5OH\)

* \(CH_4+O_2\xrightarrow[xt]{t^\circ}HCHO+H_2O\)

\(3C_2H_2\xrightarrow[C]{600^\circ C}C_6H_6\)

\(C_6H_5CH_3+Br_2\xrightarrow[Fe]{}o\text{-}C_6H_4CH_3Br\)

* \(o\text{-}C_6H_4CH_3Br+NaOH\left(\text{đặc}\right)\xrightarrow[xt,p]{t^{\circ}}o\text{-}C_6H_4CH_3OH+NaBr\)
