Butanediol (BDO)

丁二醇 (BDO)

 

丁二醇(BDO) 生产技术

 

1,4-丁二醇(BDO)一种低粘度甘醇,通常作为合成其他化学品或聚合物的中间体。由于其具有两个高反应活性的双功能羟基, 1,4-丁二醇的应用十分广泛,包括在一体化装置中生产四氢呋喃THF 和γ-丁内酯(GBL),聚氨脂,弹性纤维,热塑性弹性体,混纺弹力布,聚对苯二甲酸丁二醇酯(PBT),均聚物和共聚物塑料以及其他产品。

 

CONSER 的技术是基于马来酸酐(MAN)和甲醇酯化,然后加氢,同时联产BDO, THF 和GBL。 该工艺的最终产品分布灵活度高,产品纯度高,还可很好的与上游的马来酸酐技术结合起来。

 

CONSER也能提供最近出现的基于生物质丁二酸生产BDO 的路线。如需要更多关于这方面的信息,参见网页:“生物基丁二醇(BIO-BDO)“

Butanediol (BDO)

 

TECHNOLOGY FOR THE PRODUCTION OF BUTANEDIOL (BDO)

 

1,4 Butanediol (BDO) is a low viscosity glycol used as intermediate for the synthesis of other chemicals and polymers.
Thanks to the high reactivity of the two bi-functional OH groups, Butanediol is used in a wide variety of applications, including: Tetrahydrofuran (THF) and Gamma-Butyrolactone (GBL) co-production in integrated plants, Polyurethanes, Elastic Fibres, Thermoplastic Elastomers, Spandex, Polybutylene-Terephthalate (PBT), Homopolymers and Copolymers Plastics and others.

 

CONSER technology is based on the esterification of Maleic Anhydride with methanol, followed by hydrogenation of the resulting ester, and the consequent co-production of BDO, Tetrahydrofuran (THF) and Gamma-Butyrolactone (GBL). The process allows very high flexibility in the final products distribution, with the highest purity standards, and it can be well integrated with the upstream Maleic Anhydride technology.

 

CONSER is able to provide the technical design also for emerging Butanediol biological route from bio-based Succinic Acid (BIO-BDO). For additional information on the latter, see ‘Bio-Butanediol (BIO-BDO)’ page.
