1,4-Butanediol Uses

1,4-Butanediol is a fundamental chemical and terrific chemical basic material. It is commonly used in the production of PBT design plastics and fibers, and the synthesis of tetrahydrofuran (THF) and polytetramethylene ether glycol (PTMEG, acquired by polymerizing THF)., polyether-type high-performance elastomer and spandex flexible fiber (manufactured from PTMEG and diisocyanate, and so on), unsaturated polyester product, polyester polyol, butylene glycol ether solvent, along with pharmaceutical and aesthetic markets. 1,4-butanediol can additionally be used to develop N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1,3-butadiene, and more.

Y-butyrolactone, the downstream item of 1,4-butanediol, is the raw product for the production of 2-pyrrolidone and N-methylpyrrolidone products, where a collection of high value-added items such as vinylpyrrolidone and polyvinylpyrrolidone are acquired. Frequently utilized in pesticides, medicines, cosmetics and various other locations.

In the field of polyurethane, together with being taken advantage of to produce polytetrahydrofuran polyol, it is mainly utilized to synthesize polyester diol and is utilized as a chain extender for elastomers and microporous polyurethane shoes items. Polybutylene adipate-based polyurethane has great condensation sex.

1,4-butanediol Preparation Method

There are more than 20 production methods for 1,4-butanediol, however just 5 to 6 are truly industrially created. Today, the major commercial methods consist of enhanced Reppe method, maleic anhydride hydrogenation method, maleic anhydride esterification hydrogenation technique, and ring Oxygen lp approach and butadiene technique.

The first process innovation efficiently created by Reppe in Germany in the 1930s was to utilize acetylene and formaldehyde as resources to manufacture 1,4-butynediol and then militarize hydrogenation to synthesize 1,4-butanediol. Companies such as BASF, ISP and Dupont This method has actually always been made use of, and most domestic manufacturing companies presently use the acetylene method. my nation’s Shanxi Sanwei Group Co., Ltd. embraces an improved GAF’s low-pressure slurry butanediol manufacturing process, making use of calcium carbide acetylene as resources and making use of the low-pressure slurry bed Reppe approach to generate butanediol.

In the 1970s, Japan’s Mitsubishi Chemical Firm successfully established a butadiene acetoxy procedure course using butadiene and acetic acid as resources, and built a number of production systems in Japan, South Korea, Taiwan, China and other places. Hereafter, Japan’s Tokuyama Soda Firm effectively created and industrialized the butadiene chlorination method. This process chlorinated butadiene in the gas phase at 260 to 300 ° C to create 3,4-dichlorobutene-1 and 1. 4-Dichloroprene-2, the former is utilized to produce chloroprene rubber, and the last is hydrolyzed to create 1,4-butanediol.

The British company Davy (currently Kvaerner) developed the maleic anhydride esterification and hydrogenation approach. First, the maleic anhydride and a monohydric alcohol are esterified to develop a maleic acid diester, and afterwards catalytic hydrogenation is performed at 150 ~ 240 ℃ and 2.5 ~ 5MPa. 1,4-butanediol is gotten. Shandong Shengli Oilfield Petrochemical Co., Ltd. introduced the British Davy Company’s innovation for the esterification and hydrogenation of maleic anhydride to produce 1,4-butanediol. Another hydrogenation process utilizing maleic anhydride as basic material was created by Mitsubishi Firm of Japan. Initially, in the visibility of Ni-Re stimulant, the reaction pressure is 0.08 MPa, and the reaction temperature has to do with 260 ° C. Maleic anhydride is hydrogenated to create Y-butyrolactone. and tetrahydrofuran, and afterwards utilize a molybdenum-chromium driver with K2O as a cocatalyst to catalytically hydrogenate Y-butyrolactone to create 1,4-butanediol at 10Mpa and 250 ° C. The main benefit of this approach is that during the response Essential fine chemicals tetrahydrofuran and gamma-butyrolactone can be gotten.

Kuraray Company of Japan and Arco Corporation of the United States have actually developed an approach for generating 1,4-butanediol making use of propylene oxide as raw material. Initially, propylene oxide is isomerized to create allyl alcohol, and allyl alcohol is created under the action of a rhodium catalyst., liquid-phase hydroformylation to generate 4-hydroxybutyraldehyde, and afterwards hydrogenation to create 1,4-butanediol.

In the 1990s, Lyondell (previously Arco Chemical Firm) in the United States efficiently created an allyl alcohol production procedure using propylene oxide as resources, and developed a 50,000-ton/ year manufacturing device in Texas, the United States. Dalian Chemical Sector in Taiwan Co., Ltd.’s 130,000-ton butanediol plant adopts the propylene alcohol technique. In the 1990s, the British BP and the German Lurgi Business collectively developed the Geminox procedure making use of C4 fraction as basic material, that is, n-butane was first oxidized to maleic anhydride, after that hydrated to manufacture maleic acid, and after that hydrogenated to get 1,4-butane. Diol simplifies the process, reduces manufacturing prices, and makes it a lot more competitive.
