1,4 Butanediol (BDO)

CAS:110-63-4

Butanediol
1,4 Butanediol

Production

1,4-Butadediol is a diol that can be obtained by 4 different processes. The first one is the Reppe process which consist of the reaction between the acetylene and the formaldehyde. In 1930, the BDO synthesis has evolved to the developments of the second process, the Davy Process which is producing BDO from maleic anhydride / succinic acid. The third process is the LyondellBassell process that allows use of BDO from Propylene Oxide. The last one is the Geminox Process-BP chemicals using BDO from Butane.

Uses

BDO is commonly used as solvent but also in PBT (Polybutylene terephthalate), COPE (Thermoplastic Copolyester Elastomers), TPU (Thermoplastic Polyurethane), PU (Polyurethane), Resins, PTMEG : Spandex fibres (polyester + diisocyanate) and Copolyester for Hot Melt Adhesive. Prohibited application are fore example cosmetics, personal care or coating.

The effect of BDO on health is the same as GHB drug.
