Substitute the equation: a) Al4C3 → CH4 → CH3Cl → C3H8 → glycerin → copper (II) glycerate; b) СaC2 → C2H2 → CH3COH → CH3CH2OH → C2H5-O-C2H5.

Let us write down the equations for the transformation chains:
a) Al4C3 + 12H2O = 3CH4 + 4Al (OH) 3 – hydration reaction, methane was obtained;
CH4 + Cl2 = CH3Cl + HCl – substitutions, methane chloride is released;
CH3Cl + 2Na + C2H5Cl = C3H8 + 2NaCl – propane obtained from Würz reactions;
C3H8 + 3Cl2 = C3H5Cl3 + 3HCl – substitution, trichloropropane is formed;
С3Н5Cl3 + 3NaOH = C3H5 (OH) 3 + 3NaCl – exchange, glycerol was obtained;
CH2 (OH) – CH (OH) – CH2 (OH) + Cu (OH) 2 = CH2 (OH) – CH (OH) – CH2 (O) – Cu – (O) – CH2 -CH (OH) – CH2 (OH) + 2H2O – qualitative reaction to glycerin, copper glycerate is formed.
b) CaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydration, acetylene is formed;
С2Н2 + Н2О = Н2С = СНОН = СН3 – СОН – an intermediate substance of hydration – vinyl alcohol, which isomerized to aldehyde;
СН3СОН + Н2 = СН3 – СН2 – ОН – reduction of acetaldehyde to ethanol;
С2Н5ОН + С2Н5ОН = С2Н5 – О – С2Н5 + Н2О – esterification, dimethyl ether was obtained.
