Butanediol Sample Clauses

Butanediol. 1,4-Butanediol (BDO) is a major commodity chemical that currently is manufactured exclusively through various petrochemical routes requiring feedstocks such as acetylene, butane, propylene, and butadiene. The demand for BDO stems largely from its use as an intermediate for the production of over 2.5 million tons of PBT plastic resins, polyurethane thermoplastics, co-polyester ethers, and spandex fibers. Given the importance of BDO as a chemical intermediate and the issues associated with petroleum feedstocks, alternative low-cost renewable routes from sugars have been sought. Genomatica has engineered the first direct routes to BDO in E. coli and has developed a preliminary process for the production and recovery of BDO from renewable carbohydrate feedstocks. This process has been demonstrated at both lab (2-30 L) and pilot (3000 L) scales and work continues […***…].
