ptoluenesulfonihappo
Ptoluenesulfonihappo, known in English as p-toluenesulfonic acid (PTSA), is an organosulfur compound that acts as a strong, non-volatile Brønsted acid. It is the para isomer of benzenesulfonic acid, with the chemical formula C7H8O3S. The molecule consists of a benzene ring bearing a para-methyl group and a sulfonic acid group (SO3H). PTSA is a solid at room temperature and is highly soluble in water and many organic solvents.
PTSA is commonly used as a catalyst in a wide range of organic reactions due to its
In practice, PTSA serves as a versatile acid catalyst in esterifications, acetalizations, hydrolysis, and other acid-catalyzed
Safety considerations: PTSA is corrosive and an irritant to skin, eyes, and lungs. It should be handled
