• Chemicals

The "para-toluenesulfonic acid" manufactured by Meiyu Industries is a substance that is not commonly known to the public as it is not a final product. When producing esters from alcohols as organic acids, para-toluenesulfonic acid can be considered an ideal catalyst as it dissolves well in raw materials. Additionally, it is soluble in water and many organic solvents, and the nucleophilicity of the conjugate base (toluenesulfonate anion, CH3C6H4SO−3) is low, which makes it widely used as an acid catalyst in organic synthesis. It can be used for various applications, including stabilizers, acid catalysts, and formulation materials. This substance, which is surprisingly close and necessary, will continue to contribute to our lives and society.
