Methanol  ( methyl alcohol ) 甲醇

_{Ethanol has higher boiling point than Methanol.}

_{Methanol boiling point 148.5°F, 64.7°C (65)}

Drinking just 25-90 mL (0.7-3.0 ounces) of methanol can be fatal without proper medical treatment. Since methanol is an industrial chemical, it should not be consumed in any quantity, just as people would normally not mix gasoline or other industrial chemicals into legitimate alcoholic beverages.

Ethanol ( ethyl alcohol )  乙醇

boiling point of 78 °C (173 °F),  173.1 F (78.37 C). (78)

Aldehydes 甲醛  and ketones 酮體

have lower boiling points compared to alcohols of similar size.

Acetaldehyde/Boiling point  68.36°F, 20.2°C

Acet aldehyde 乙醛 

Acetaldehyde/Boiling point68.36°F, 20.2°C (same as Aldehyde)

李時珍《本草綱目》：

“ 燒酒非古法也，自元時始創。

其法用濃酒和糟，蒸令汽上，用器承取滴露，

凡酸壞之酒，皆可蒸燒”。
