这关键区别between ethyl alcohol and isopropyl alcohol is that乙醇是一种primary alcohol异丙醇是一种secondary alcohol。
Ethyl alcohol and isopropyl alcohol are alcoholic compounds since they have a –OH group. These are the smaller alcohols in the series with two or three carbons. The OH group is attached to ansp3 hybridized碳。两者都是极性液体,并且具有形成的能力hydrogen bonds。因此,这两种化合物都具有相似的物理和化学特性以及一些差异。

什么是乙醇?
乙醇通常是乙醇。乙醇是一种简单的酒精,具有C的分子公式2H5哦。这是一种清晰,无色的液体,具有特征性的气味。此外,该化合物是一种易燃液体。它的熔点为-114.1oC和沸点是78.5oC. Ethanol is polar due to the electronegativity difference between the oxygen and hydrogen in the –OH group. Also, due to –OH group, it can form hydrogen bonds.

Ethyl alcohol is very useful as a beverage. According to the ethanol percentage, there are different types of beverages such as wine, beer, whiskey, brandy, arrack, etc. Ethanol can be easily obtained by the sugar fermentation process using the zymase enzyme. The enzyme is naturally present in yeast; thus, in anaerobic respiration, yeast can produce ethanol. Moreover, this ethanol is toxic to the body, and it is converted to乙醛在肝脏中,这也有毒。另外,它可以作为一种防腐剂,可通过去除微生物来清洁表面。此外,我们可以将其用作车辆中的燃料和燃料添加剂。乙醇可与水混溶,并且也可以作为良好的溶剂。
什么是异丙醇?
异丙醇,也称为2-丙醇,具有与丙醇相同的分子式。它的分子量约为60 g mol-1。分子公式为c3H8O.因此,异丙醇是丙醇的异构体。该分子的羟基附着在碳链中的第二个碳原子上。因此,这是二次酒精。

此外,异丙醇的熔点为-88oC, and the boiling point is 83oC. It is miscible with water and stable under normal conditions. This is a colorless, clear, flammable liquid. Since this is a secondary alcohol, it undergoes all the reactions typical to a secondary alcohol. Furthermore, it oxidizes violently to produce acetone. As for usage, this alcohol is useful as a solvent and used in pharmaceuticals, household products, and personal care products. We can also use it to make other chemicals.
乙醇和异丙醇有什么区别?
乙醇是乙醇,异丙醇是2-丙醇。这些是小的酒精化合物。乙醇和异丙醇之间的主要区别在于乙醇是原发性酒精,而异丙醇是二次酒精。此外,乙醇和异丙醇之间的重要区别在于,乙醇具有两个碳,而异丙醇具有三碳。
在考虑这些化合物的命名法时,在乙醇命名法中,具有 - OH组的碳排名第一。在异丙基命名法中,带有-OH组的碳获得第二名。除此之外,当异丙醇被氧化时,会产生丙酮。然而,通过乙醇氧化产生醛。此外,乙醇和异丙醇之间的另一个显着差异是乙醇适合饮用,但异丙醇不适合饮用。实际上,异丙基饮酒可能是有毒的。
摘要 - 乙醇与异丙醇
乙醇和异丙醇是两种不同类型的酒精化合物。它们是甲醇之后最小的醇。乙醇和异丙醇之间的主要区别在于乙醇是原发性酒精,而异丙醇是二次酒精。

我可以将63%的乙醇洗手液与91%的异丙醇混合以增加洗手液的酒精含量吗?
您可以,但您不需要。您已经遇到了CDC建议的乙醇含量高于60%。
