Ethanol classification, standard and

酒精广泛应用于食品、化学、医药、染料等行业，酒精又是十分重要的清洁能源。通常，酒精按含杂质多少分为：无水酒精、食用酒精、工业酒精。

Ethanol widely applies to many industries such as food, chemistry, medicine, dye and etc. In general, ethanol is divided to anhydrous ethanol, edible ethanol and industrial ethanol according to its impurity content.

一、无水酒精Anhydrous ethanol

无水酒精产品质量执行中华人民共和国国家标准GB/T678-2002《化学试剂－无水乙醇标准》。The product quantity of anhydrous ethanol execute the state criteria of the People's Republic of China

用途：化学试剂、化学原料、防腐剂、消毒、燃料、有机溶剂等。

Application: chemical reagent, chemical material, preservative, disinfection, fuel, organic solvent and etc.

二、食用酒精Edible ethanol

食用酒精产品质量执行中华人民共和国国家标准GB10343-2002适用于谷物、薯类、糖密为原料，经发酵、蒸馏而制成的含水酒精，为食品工业专用的食用酒精。

The product quantity of edible ethanol executes the state criteria of the People's Republic of China GB10343-2002, which applies to the aqueous ethanol make from grains, yams or molasses as raw material and through fermentation and distillation. It is the appropriative edible ethanol for food industry.

用途：白酒、饮料、乙酸乙酯、丁醇、丙酮、医药等。

Application: distilled spirit, drink, ethyl acetate, butanol, acetone, medicine and etc.

三、工业酒精

工业酒精产品质量执行中华人民共和国国家标准GB/适用于谷物、薯类、糖密为原料，经发酵、蒸馏而制成的含水工业酒精。其杂质指标比食用酒精宽松。按其生产的酒精不得用于食品、饮料。The product quantity of industrial ethanol executes the state criteria of the People's Republic of China GB/, which applies to the aqueous ethanol make from grains, yams or molasses as raw material and through fermentation and distillation. Its impurity indicator is easier than edible ethanol. The ethanol that produced following this standard cannot be used for food and drink.

工业酒精《GB/》标准

用途：燃料、有机溶剂、乙烯、橡胶、聚乙烯、聚氯乙烯、染料、农药等。

Application：fuel, organic solution, ethane, rubber, polyethylene, PVC, dye, pesticide and etc.
