1,4-Butanediol

BDO is a clear, colorless, hygroscopic liquid with low volatility and high stability. It is a versatile building block for high-value derivatives including tetrahydrofuran (THF), gamma-butyrolactone (GBL), and polybutylene terephthalate (PBT). Our BDO is produced via the Reppe or Davy process with tight impurity control to meet the demanding requirements of polymerization and pharmaceutical applications.

Key Advantages

· High Purity & Consistency: Strict control of by-products (2-methyl-1,4-butanediol, 1,4-butanediol monoacetate) ensures stable polymerization performance.

· Low Moisture & Acidity: Butanediol is crucial to the reaction involving polyurethanes and polyesters, because water causes chain termination.

· Versatile Platform Chemical: Serves as precursor for multiple high-value downstream products.

· Thermal Stability: Maintains quality under standard storage conditions for up to 24 months.

Main Applications

·THF Production: Primary feedstock for tetrahydrofuran, which converts to PTMEG for spandex fibers.

· GBL & NMP: Precursor for gamma-butyrolactone and N-methylpyrrolidone (electronics cleaning solvents).

· PBT Engineering Plastics: Monomer for polybutylene terephthalate used in automotive connectors and electronics housings.

· Polyurethane: Chain extender and crosslinker for PU elastomers, adhesives, and coatings.

· Pharmaceutical Intermediates: Synthesis of vitamin B6, anesthetics, and other APIs.

· Cosmetics: Butanediol is a humectant and solvent in personal care formulations.

Packaging & Shipping

· Standard Packaging: 200 kg net in new galvanized drums, 1.2 MT IBC totes, or ISO tank (22 MT per tank).

· Container Loading: 80 drums per 20' GP (16 MT net).

· Storage: Keep tightly sealed in a cool, dry place under nitrogen blanketing if possible. Avoid moisture ingress and temperatures above 40°C.

· Shelf Life: 24 months in sealed original packaging with proper storage.

FAQ

Q: Why is moisture and acidity so critical for BDO quality?

A: For polyurethane and polyester synthesis, water reacts with isocyanates to form urea and releases CO₂, causing foaming and weak bonds. Acidity acts as a catalyst for ester hydrolysis and can also neutralize amine catalysts. Even trace amounts (50 ppm moisture or 0.005% acidity) significantly affect final product performance. Our 99.5% purity grade guarantees these levels below specification, saving you from failed batches.

Q: What's the difference between BDO, GBL, and THF?

A: BDO is the base raw material. GBL (gamma-butyrolactone) is produced by dehydrogenation of BDO and is used as a solvent and intermediate for NMP/2-P. THF (tetrahydrofuran) is produced by cyclodehydration of BDO and is used as a solvent for PVC and precursor to PTMEG. Each downstream product has distinct solvent properties and applications. We supply BDO to manufacturers who produce these derivatives.
