(2) Product

Company existing three sets of 1, 4 - butanediol production unit, the total capacity of 200000 tons/year. On December 19, 2001, the company introduced the ISP companies in the United States patent production technology, built the first set of 25000 tons/year alkyne aldehyde method 1, 4 - butanediol production device (after the expansion, production capacity has reached 30000 tons/year), rosemount bus type DCS control system is adopted in the system; In June 2006, the company built a second set of 45000 tons/year alkyne aldehyde method 1, 4 - butanediol production equipment; In 2010, the company is given priority to with introduction of software technology, import of proprietary equipment and key equipment, using the world's most advanced maleic anhydride esterification hydrogenation method (DPT) production technology, built in the third set of 1, 4 - butanediol production device (project foreign licensing capacity of 75000 tons, the design capacity of 100000 tons, the maximum capacity of 125000 tons), the control system adopts yokogawa company fieldbus control system. Company is the domestic high technology, large-scale complete industrial chain of 1, 4 - butanediol and downstream products manufacturing enterprises.

    Second, the product is introduced Properties: 1, 4 - butanediol (BDO) is a colorless oily combustible liquid, can be immiscible with water, but soluble in methanol, ethanol, acetone, slightly soluble in ether. Boiling point 235 ℃, melting point is 20.1 ℃, flash point (opening) 121 ℃, the relative density (d4-20) 1.017, temperature 370 ℃, the refractive index of 1.446. Purpose: 1.1, 4 - butyl glycol is a kind of important organic chemical and fine chemical raw materials, it is the production of poly (butyl glycol terephthalate (PBT) engineering plastics and the basic materials of PBT fiber, and PBT plastic is one of the most promising five engineering plastics. 2.1, 4 - butyl glycol is the production of tetrahydrofuran (THF), the main raw material. Tetrahydrofuran is an important organic solvent, the aggregate production of poly (tetramethylene ether glycol (PTMEG) is the basic material in the manufacture of the high elasticity of spandex. Spandex mainly for the production of sportswear, swimwear high elastic fabrics. 3.1, 4 - butyl glycol is the production of gamma butyrolactone main raw material. Gamma butyrolactone mainly for the production of alpha - pyrrolidone
