Sulfolane A, Anhydrous
Sulfolane A, Anhydrous is a dipolar, aprotic solvent with 99.9% purity that is commonly used in various industrial applications.
Sulfolane A, Anhydrous, also known as tetramethylene sulfone, is an extremely dipolar, aprotic organosulfur solvent used for its solvency of other polar compounds. It has a low viscosity, enabling improved fluidity for easier pump, transport, and handling. Due to its low toxicity and minimal skin penetration, it serves as an alternative to NMP and other toxic chemicals in applications focused on enhancing worker health and safety. Sulfolane A, Anhydrous exhibits remarkable stability under high temperatures, maintaining its integrity, even up to 430°F. This stability makes it well suited for a variety of demanding industrial processes. It is extensively utilized as an industrial solvent across multiple applications, including the production of coatings, inks, and paint strippers. Additionally, it is integral in pharmaceutical synthesis, water treatment processes, and electronics manufacturing. Its application extends to petroleum refineries, particularly in the extraction of aromatic hydrocarbons to purify natural gas. Sulfolane A, Anhydrous can be diluted with water to decrease its freezing point, improving its utility and storage in colder environments.

Organosulfur solvent Low-viscosity liquid Dipolar, aprotic nature Low toxicity High stability High thermal stability up to 430°F Low skin penetration
Problems Solved
There is a growing need within industrial operations to address the difficulty of dissolving polar molecules, a common challenge that impedes efficient production processes. Many traditional solvents tend to degrade when exposed to elevated temperatures, leading to significant performance issues and potential disruptions in production. The pervasive concerns about worker health and safety, especially associated with the use of potentially harmful solvents like n-methyl-2-pyrrolidone (NMP), have further driven the demand for safer alternatives.
Applications
Coatings Paint strippers Inks Electronics Petroleum refining Pharmaceuticals Water treatment
