TL;DR What is 1,4-Butanediol? 1,4-Butanediol (BDO) is a colorless, hygroscopic liquid used widely as a chemical intermediate. Chemically, it’s a four-carbon diol that participates in esterification and polymerization reactions to build high-value materials (see Applications below). Industrial Applications (Where BDO Creates Value) 1) THF → PTMEG → Spandex value chain 2) PBT engineering plastics 3) […]

Why Sustainability Matters in BDO 1,4-Butanediol (BDO) is a workhorse intermediate in the production of spandex (THF/PTMEG), polybutylene terephthalate (PBT), polyurethanes, and gamma-butyrolactone (GBL). Traditionally, it’s made from fossil-based acetylene, butadiene, or propylene oxide routes. But growing pressure for decarbonization, ESG compliance, and circular economy targets is accelerating the shift to bio-based alternatives. Biological Pathways […]
