=== Dehidrasi ===
Asam kuat kang higroskopis banget kayata asam sulfat bakal njalari dehidrasi etanol
:2 CH<sub>3</sub>CH<sub>2</sub>OH → [[dietil eter|CH<sub>3</sub>CH<sub>2</sub>OCH<sub>2</sub>CH<sub>3</sub>]] + [[air|H<sub>2</sub>O]] (ing suhu 120'C)
:CH<sub>3</sub>CH<sub>2</sub>OH → [[etilena|H<sub>2</sub>C=CH<sub>2</sub>]] + [[air|H<sub>2</sub>O]] (ing suhu 180'C)
Larik 141:
=== Oksidasi ===
Etanol bisa dioksidasi dadi [[asetaldehida]], banjur dadi [[asam asetat]]. Ing awak manungsa, reaksi oksidadi iki dikatalisis
:C<sub>2</sub>H<sub>5</sub>OH + 2[O] → CH<sub>3</sub>COOH + H<sub>2</sub>O
Kasil oksidasi etanol, asam asetat,
=== Pembakaran ===
[[Pembakaran]] etanol bakal ngasilaké [[karbon dioksida]] lan [[banyu]]:
:C<sub>2</sub>H<sub>5</sub>OH(g) + 3 O<sub>2</sub>(g) → 2 CO<sub>2</sub>(g) + 3 H<sub>2</sub>O(l);(ΔH<sub>r</sub> = −1409 kJ/mol<ref>{{cite journal|title=Heats of Formation of Simple Organic Molecules|author=Frederick D.
