G-Butyrolactone

γ-丁内酯(GBL)

 

γ-丁内酯(GBL)生产技术

 

γ-丁内酯(GBL)是一种易吸湿的无色,与水互溶的液体,它是生产诸多化学品的中间体。                                                                                                                                     

γ-丁内酯(GBL)主要用于生产用途广泛的工业化学品N-甲基吡咯烷酮 和2-吡咯烷酮。由于其很强的溶解特性,GBL还用于电子行业中电路版的清洗和脱漆。

 

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还可以提供从BDO 脱氢生产γ-丁内酯的工艺设计。如需要关于这方面的更多信息,参见网页“从BDO生产γ-丁内酯”

Tetrahydrofuran

四氢呋喃 (THF)

 

四氢呋喃生产技术

 

四氢呋喃(THF)是一种易吸湿的有机化合物,低粘度、无色、与水互溶的有机液体。主要是作为聚合物的前驱体。

 

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的工艺生产高纯度THF,非常适合下游生产PTMEG。

Gamma-Butyrolactone from BDO

Gamma - Butyrolactone from Butanediol dehydrogenation (GBL)

 

TECHNOLOGY FOR THE PRODUCTION OF GAMMA-BUTYROLACTONE FROM BUTANEDIOL DEHYDROGENATION (GBL)

 

γ-Butyrolactone (GBL) is a hygroscopic colorless, water-miscible liquid used as an intermediate in the production of other chemicals.                                                                                                                                          

GBL is mainly used in the manufacturing of N-Methyl Pyrrolidone (NMP) and 2-Pyrrolidone, which are widely used as industrial chemicals. Thanks to its strong solvency properties, GBL is also used as circuit board cleaning in electronics and paint stripping.

 

CONSER, having an extensive experience in the branch of Maleic Anhydride derivatives - Butanediol, Tetrahydrofuran, Gamma-Butryrolactone -, developed a process for the production of GBL from Butanediol dehydrogenation. This technology has many benefits, such as: nearly total BDO conversion; very high GBL selectivity; low catalyst consumption; high GBL purity (electronic grade); low utilities consumption.

 

CONSER is able to provide the technical design also for the co-production of Gamma-Butyrolactone, Butanediol and Tetrahydrofuran from Maleic Anhydride. For additional information on the latter, see ‘Gamma-Butyrolactone’ page.

Tetrahydrofuran

Tetrahydrofuran (THF)

 

TECHNOLOGY FOR THE PRODUCTION OF TETRAHYDROFURAN (THF)

 

Tetrahydrofuran (THF) is a heterocyclic organic compound, and is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers.

THF major use is as monomer of the Polytetramethylene Ether Glycol (PTMEG). PTMEG is a component of cast and thermoplastic urethane elastomers, polyurethane stretch fibers (Spandex), and high-performance Copolyester-Polyether elastomers (COPE). Tetrahydrofuran is also used as a solvent in polyvinyl chloride (PVC) cements, pharmaceuticals and coatings, precision magnetic tape manufacture.

 

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 Tetrahydrofuran, Butanediol (BDO) 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 process provides THF with the best purity grade, which is suitable for the downstream PTMEG production.
