Also used in the stereoselective synthesis of (-)-Brevisamide. 1,4-Buta0ediol's largest use is within tetrahydrofur (THF) production, used to make polytetramethylene ether glycol, which goes mainly into spandex fibers, urethane elastomers, and copolyester ethers. It is commonly used as a solvent in the chemical industry to manufacture γ- butyrolac and elastic fibers like spandex. It is used as a cross-linking agent for thermoplastic urethanes, polyester plasticizers, paints and coatings. It undergoes dehydration in the presence of phosphori acid yielded teterahydrofuran, which is an important solvent used for various applications. It acts an intermediate and is used to manufacture polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) and polyurethane (PU). It finds application as an industrial cleaner and a glue remover. 1,4-butaediol is also used as a plasticiser (e.g. in polyesters and cellulosics), as a carrier solvent in printing ink, a cleaning agent, an adhesive (in leather, plastics, polyester laminates and polyurethane footwear), in agricultural and veterinary chemicals and in coatings (in paints, varnishes and films). 1,4-Butaediol Preparation Products And Raw materials Raw materials : Formaldehyde-->Nickel-->1,3-BUTADIENE-->A , cetylene-->2,3- Butaedione-->2-Butyne-1,4 , -diol-->Chloroprene-->cis-1,4-Dichloro-2-but , ene-->3- hydroxy-2-methyl propionaldehyde-->DIMETHYL MALEATE-->2-HYDROXYTETRAHYDROFURAN Prepa , ration Products:Tetrahydrofuran-->Gamma Butyrolacton-->Polyurethane foams-- >Triethylene glycol dimethacrylate-->1,4-Dibromobutae-->Poly(but , ylene terephthalate)-->GD visible light curing composite resin-->PolyesterPolyol-->2,3- Dihydrofur , an-->1,4-BUTAEDIOL DIACRYLATE-->4-Hydroxybutyl acrylate-- >Polyvinylpyrrolidone-->Busulf , an-->Pyrrolidine It mainly produces and develops local anesthetics, pharmaceutical intermediates, organic solvents, and steroids and other APIs.

Plastic tower packing has the characteristics of light weight, heat resistance and chemical corrosion resistance, including tower packing made of PP, PE, RPP, PVC, CPVC, PVDF and other materials. Plastic tower packing mainly includes: multi-faceted hollow ball, rosette, Haier ring, ladder ring, conjugate ring, Pall ring, intalox saddle ring, hetero saddle ring, conjugate ring, flat ring, Raschig ring, snowflake ring, six-sided shaped ring, rotating ring, pentagonal ring, conical ring, net ring, cross spherical ring, floating ball, liquid surface covering ball, diamond covering ball, structured packing, etc. Plastic Polyhedral Hollow Ball NAIKE Plastic polyhedral hollow ball is a kind of plastic random packing made of two hemispheres. Each hemisphere is made of many flabellate vanes. Tri Pack Plastic Tri Pack tower packing provides maximum surface contact between the gas and the scrubbing liquid by facilitating continuous formation of droplets throughout the packed bed. Plastic Hollow Floatation Ball Plastic hollow floatation ball is produced by advanced technology, it can be continuous used for a long time under the working temperature of 60-150 degree. Plastic Structured Packing Plastic Perforated Plate Corrugated Packing is made of improved polypropylene and the other material, and its performance is similar to the metallic perforated corrugated packing with the same dimension. Plastic Pall Ring NAIKE Plastic Pall Ring is versatile. This product was advanced on the basis of Plastic Rasching Ring, and compared with it, both of them have similar cylindrical dimensions. Plastic Tellerette Ring NAIKE Plastic Tellerette Ring was designed by Tell A J in 1956, so-called Teller Rosette Ring. The Packing liked ellipse s consist of many enlaced cirques. Plastic Intalox Saddles Ring NAIKE Plastic Intalox Saddle Ring'middle part of this packing is the arc liquid channel so that the flow of air along with arc liquid channel. Plastic Snowflake Ring For the maximum tower of performance, Snowflake Ring offers a unique combination of superior separation efficiency and high capacity. It is widely applied in the Chemical Processing Industry. Plastic Cascade Ring NAIKE Plastic Cascade Mini Ring is made from heat resistant and chemical corrosion resistant plastics, including PE, PP, PVC, CPVC, PVDF, etc. Plastic Raschig Ring NAIKE Plastic Raschig rings are pieces of the tube (approximately equal in length and diameter) used in large numbers as a packed bed within columns for Distillations and other chemical engineering processes. Q-pack Plastic Q-Pack Tower Packing is a kind of high-capacity plastic random packing. It has a special octagonal structure. This structure has a geometric surface, large holes and a small volume. Lanpack Plastic Lanpack Packing For Tower Packing is the most distinguishing feature. This design enables an extraordinarily high scrubbing efficiency while minimizing the amount of media and packing depth required. Application of Plastic Tower Packing Plastic tower packing has the characteristics of large void ratio, low pressure drop and mass transfer unit height, high flooding point, sufficient vapor- liquid contact, and high mass transfer efficiency. Plastic tower packing is widely used in various mediums in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries in packed towers with a temperature of 60-280℃
