What kind of substance is THF? What kind of substance is THF? THF  is a chemical reagent of thorium fluoride.   Alias:  tetrahydrofuran , 1.4-epoxybutane, tetramethylene oxide, oxyheterocyclic pentane, monooxypentacyclic, tetrahydroxycyclocene, polytetramethylether glycol, tetramethylene oxide, oxyheterocyclic pentane, monooxyacyclic   CAS: 109-99-9 Molecular formula: C4H8O Molecular weight: 72.11 PSA 9.23000 LogP 0.79680 Merck 9211 Refractive index n20/D 1.40 Miscible Boiling point 65-67 ° C (l In industrial production, sugar aldehyde was first used as raw material. The mixture of sugar aldehyde and steam was introduced into the reactor filled with zinc chromium manganese metal oxide (or palladium) catalyst, and the carbonyl group was removed at 400-420 ℃ to form furan; Then tetrahydrofuran was prepared by hydrogenation of furan at 80-120 ℃ using skeleton nickel as catalyst. The production of 1 ton of tetrahydrofuran by this method requires about 3 tons of polysacch...

Forecast and analysis on the market status and development trend of China's BDO industry in 2023  China Business Information Network News:  BDO , as an important basic raw material for fine chemicals, is widely used in textile, chemical and other fields, among which PTMEG and PBT engineering plastics are the traditional application fields of BDO. Under the background of “carbon peak” and “carbon neutralization”, in order to reduce carbon emissions, emerging fields in the chemical industry, such as biodegradable materials, new energy vehicles, thermoplastic elastomers, are expected to lead the new development of low-carbon chemical industry. As an important basic chemical raw material for biodegradable materials, new energy vehicles, thermoplastic elastomers and other industries,  BDO  will usher in new growth points of the industry.   Operating rate analysis   BDO is widely used as the synthetic raw material of PBS series biodegradable materials, and is an ...
