p-Toluenesulfonic acid (esterification, acid catalyst)

p-Toluenesulfonic acid (esterification, acid catalyst)

An ideal acid catalyst! Contributes to speeding up the rate of specific chemical reactions! No change in the substance itself before and after the reaction.

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.

Composite catalysts that assist in the efficient synthesis of high value-added materials [Shinshu University]

Composite catalysts that assist in the efficient synthesis of high value-added materials [Shinshu University]

Easily synthesized from commercially available materials! Successfully obtained oxazolidinone with good yield under mild conditions.

We will introduce the results of the development of a new acid catalyst aimed at the efficient synthesis of "cyclic carbonate," used in electrolytes for lithium-ion batteries, and "oxazolidinone," which is widely present in pharmaceuticals. Conventional technologies have left challenges such as requiring high-temperature heating and having limited substrate generality. In this context, we successfully used magnesium iodide as a metal salt in reactions employing isocyanates to obtain oxazolidinone with good yields under mild conditions of 35°C. The production and sale of this catalyst, aimed at use in the manufacturing processes of organic materials and pharmaceuticals, is anticipated. 【Conventional Technology and Challenges】 ■ There are relatively few reports of reactions involving the mild conditions of atmospheric carbon dioxide through the simple operation of adding ligands to commercially available metal salts. ■ Requires high-temperature heating. ■ Limited substrate generality. *For more details, please refer to the PDF document or feel free to contact us.
