Frequently Asked Questions (FAQs)

What is Sulfolane CAS 126-33-0 used for?

Sulfolane CAS 126-33-0 is primarily used as a polar aprotic solvent in extraction processes, such as separating aromatics from aliphatics in petrochemical refining. It also serves as a medium in pharmaceutical synthesis, polymer dissolution, and gas purification.

Is Sulfolane safe to handle?

Yes, Sulfolane has low acute toxicity and is non-flammable under normal conditions. It features a high flash point (>150°C) and is stable, but standard PPE (gloves, goggles) is recommended during handling to avoid skin or eye irritation.

What is the purity level of your Sulfolane?

Our Sulfolane CAS 126-33-0 is available at ≥99.5% purity, verified by gas chromatography (GC). Custom purities can be discussed based on specific application needs.

How should Sulfolane be stored?

Store in a cool, dry place in tightly sealed containers, away from strong oxidizers. It remains stable at room temperature and has a shelf life of at least 2 years when properly stored.

Can Sulfolane be recycled?

Absolutely—Sulfolane can be recovered via vacuum distillation with efficiencies exceeding 95%, making it a sustainable choice for large-scale operations.

What packaging options are available for Sulfolane CAS 126-33-0?

We offer flexible packaging including 200 kg drums, 1,000 kg IBC totes, and bulk tankers to suit your volume requirements.
