1. Product Introduction
Butanediol (C₄H₁₀O₂), primarily referring to 1,4-Butanediol (1,4-BDO), is a versatile industrial diol with excellent hygroscopicity and reactivity. It is a colorless, viscous liquid widely used as a precursor for polymers, solvents, and specialty chemicals. Produced via catalytic hydrogenation of maleic anhydride or fermentation processes, it is a critical intermediate in the synthesis of polyesters, polyurethanes, and pharmaceuticals.
