This is Welinks's video of loading BDO. BDO (1.4-Butanediol) is a high-quality intermediate. 1.4-Butanediol and its derivatives are widely used for producing plastics, solvents, electronic chemicals and elastic fibers. 1,4-butanediol intermediate is a versatile diol precursor to numerous derivatives such as esters, carbamates, polyesters and urethanes.

1.4-Butanediol is an important raw material for the production of spandex, plastics, elastomers and films. BDO is used as a base material as well as a starting material for other SA derivatives such as THF and GBL. THF is produced from 1,4-DO in the presence of phosphoric acid under high temperature conditions. Figure 5 shows five known chemical processes for producing 1,4-PDO. Reppe chemistry was one of the first technologies to produce 1,4-butanediol from acetylene and formaldehyde.

1.4-Butanediol has a wide range of applications. 1.4-butanediol is used as a chain extender and polyester raw material for the production of polyurethane elastomers; esters made from 1,4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylates and polyesters 1.4-Butanediol has good hygroscopic elasticity. BDO can also prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, and can also be used in the preparation of vitamin B6, pesticides, herbicides and various process solvents, lubricants, humidifiers, softeners, adhesives and the role of brightening agents, solvents, wetting agents and plasticizers in the electroplating industry. Cross-linking agent, organic synthesis for manufacturing polyurethane with high elasticity. BDO can prepare pyrrolidone derivatives such as N-methylpyrrolidone, N-vinylpyrrolidone, etc. BDO is also used in the preparation of vitamin B6, pesticides and herbicides.

  1.4-Butanediol (Butane-1.4-diol) is an organic substance with molecular formula C4H10O2 and molecular weight 90.12. Appearance is colorless or light yellow oily liquid. Flammable, freezing point 20.1℃, refractive index 1.4461. soluble in methanol, ethanol, acetone, slightly soluble in ether. BDO is hygroscopic and has a bitter taste, but slightly sweet in the mouth. Used as solvent and humidifier, also used as plasticizer, drug, polyester resin, polyurethane resin, etc.

1.4-Butanediol ( BDO ) is used industrially as a solvent and in the manufacture of certain types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.

BDO must keep its temperature not lower than 20℃ during storage and transportation, which can avoid crystallization and facilitate loading and unloading. 1.4-Butanediol (BDO) is a colorless viscous flammable liquid with chemical formula C4H10O2, miscible with water, soluble in methanol, ethanol and acetone, slightly soluble in ether.

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

1.4-Butanediol has a wide range of uses. For the production of gamma-butyrolactone and polybutylene terephthalate, the latter being a rapidly developing engineering plastic. 1.4-butanediol is used as a chain extender and polyester raw material for the production of polyurethane elastomers and flexible polyurethane foam. The esters made from 1.4-butanediol are good plasticizers for cellulose and polyesters. 1.4-Butanediol has good hygroscopic flexibility and can be used as gelatin softener and treatment agent for cellophane and other unused paper. BDO can also prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, also used in the preparation of vitamin B6, pesticides, herbicides and the role of a variety of process solvents, lubricants, humidifiers, softness, adhesives and intermediates in the electroplating industry brightener, solvent, wetting agent, plasticizer. Manufacturing polyurethane high elasticity of cross-linking agent, organic synthesis. BDO can...
