1,4 Butanediol (BDO) & Bio-based 1,4 Butanediol (BDO)
1,4-Butanediol Chemical Structure Composition.
1,4 Butanediol (BDO) is a colorless viscous liquid 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 1,4 Butanediol (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.
Bio- Butanediol BDO is produced from sugars derived from the hydrolysis of starch, glucose syrup. Bio-BDO is produced through a single-step fermentation by a metabolically engineered strain of E.coli type bacteria.
Novamont has been conducting research to obtain sugars from lignocellulosis biomass.
Bio-butanediol (Bio-BDO) is a drop-in of BDO. Bio BDO has the same molecular structure as the fossil-based BDO but “Bio” means that the molecule was made from renewable resources.
Bio-BDO is 100% bio-based and biodegradable.
BDO and Bio-BDO are commonly used as solvent but also as building block 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.
