MESITYLENESULFONIC ACID HYDRATE - Introduction
2-Mesitylenesulfonic dihydrate(2-Mesitylenesulfonic acid dihydrate) is an organic acid with the chemical formula C9H12O6S2. The following is an introduction to its nature, use, preparation and safety information:
Nature:
2-Mesitylenesulfonic acid dihydrate is a colorless to yellow crystalline solid that is soluble in water. It has strong acidity and can react with alkali to form salt.
Use:
2-Mesitylenesulfonic acid dihydrate is often used as a catalyst and a reagent for organic synthesis. It can be used as a proton acid catalyst in a variety of organic synthesis reactions, such as esterification, acylation, condensation and other reactions. In addition, it can also be used in acid-catalyzed polymerization reactions in organic chemistry. Due to its strong acidity and solubility, it can also be used as a solvent for acid catalysis.
Preparation Method:
2-Mesitylenesulfonic acid dihydrate is usually obtained by reacting trimethylenesulfonic acid with concentrated sulfuric acid. The reaction product can be purified and obtained by crystallization.
Safety Information:
2-Mesitylenesulfonic acid dihydrate is relatively safe under normal use conditions. However, it is an organic acid and may have an irritating effect on the skin, eyes and mucous membranes. Wear appropriate protective equipment to avoid contact with skin and eyes. After use, it should be cleaned in time to avoid eating or inhaling.
