Industrial 1,4-Butanediol (BDO) 99.5%: Key Material for PBT, THF & PBAT
Industrial 1,4-butanediol at 99.5% purity is specified as a non-polymeric diol intermediate in three separate reaction networks: transesterification to polybutylene terephthalate, acid-catalyzed cyclodehydration to tetrahydrofuran, and direct esterification with aliphatic-aromatic dicarboxylic acids for polybutylene adipate-co-terephthalate. The 99.5% grade is not a single-component specification; it is defined by water mass fraction,...
