n-butane can be prepared from 1-butyne by hydrogenation reaction. 1-Butyne is reacted with hydrogen in the presence of Pd/C, it converts into 1-butene. 1-butene is again reacted with hydrogen in the presence of Pd/C, it converts into n-butane.
H C ≡ C - C H 2 - C H 3 + H 2 → P d - C H 2 C =
C H - C H 2 - C H 3 H 2 C = C H - C H 2 - C H 3 + H 2
→ P d - C H 3 C - C H 2 - C H 2 - C H 3
H C ≡ C - C H 2 - C H 3 + H 2 → P d - C H 2 C =
C H - C H 2 - C H 3 H 2 C = C H - C H 2 - C H 3 + H 2
→ P d - C H 3 C - C H 2 - C H 2 - C H 3
