一般描述

可以通过二氧化硫的催化氧化来制备硫酸。它是一种非常强的电解质,对水具有很高的亲和力。
Sulfuric acid is a strong mineral acid, that is commonly used in organic synthesis as a reagent, catalyst, and solvent. It is also useful to perform several functions, including dehydration, sulfonation, and nitration.Benzenesulfonic acid, also known as besylic acid, is a strong organic acid commonly used as an acid catalyst in various organic reactions, such as esterification, alkylation, and condensation reactions. It is also used as a sulfonating agent to introduce sulfonic acid (SO3H) groups into organic compounds, which can be useful in the synthesis of several dye intermediates.

应用

硫酸在化学工业中可用作脱水剂、催化剂和活性反应物。它还用于制备硅硫酸复合材料,这种材料用作有机合成的催化剂。
