Theko e Ntle ea Moetsi Tetrahydrofuran CAS:109-99-9

tlhaloso e khutšoanyane:

Tetrahydrofuran (THF) ke mokelikeli o se nang 'mala, o fetohang habonolo o nang le monko o kang oa ethereal kapa oa acetone 'me o kopana ka metsing le li-solvents tse ngata tsa tlhaho. Tetrahydrofuran (THF) e tuka haholo 'me e ka bola ka mocheso ho ba carbon monoxide le carbon dioxide. Polokelo e telele ha e kopana le moea le ha ho se na antioxidant e ka etsa hore THF e bole hore e be li-peroxide tse phatlohang.

Tšebeliso ea Tetrahydrofuran

Tetrahydrofuran e sebediswa tlhahisong ya di-polymer hammoho le dikhemikhale tsa temo, meriana le thepa. Mesebetsi ya tlhahiso e atisa ho etsahala ditsamaisong tse kwetsweng kapa tlasa taolo ya boenjiniere e fokotsang ho pepesehela le ho lokollwa ha basebetsi tikolohong. THF e boetse e sebediswa e le sehlahiswa (mohlala, ho kenya diphaephe) se ka fellang ka ho pepesehela haholo ha se sebediswa dibakeng tse kwalletsweng ntle le moya o lekaneng wa ho kenya moya. Le hoja THF e le teng ka tlhaho monkong wa kofi, di-chickpea tse phofshoang le kgoho e phehilweng, ho pepesehela tlhaho ha ho lebellwe hore ho tla baka kotsi e kgolo.
Butylene oxide e sebediswa e le sebolaya-dikokwana-hloko mme ha e kopane le metswako e meng. E sebediswa ho tsitsisa mafura mabapi le mmala le ho thehwa ha seretse.
Tetrahydrofuran e sebelisoa e le tharollo bakeng sa li-resin, li-vinyl le li-polymer tse phahameng; e le sebaka sa karabelo ea Grignard bakeng sa liketso tsa organometallic, le metal hydride; le tlhahisong ea succinic acid le butyrolactone.
Solvent bakeng sa li-polymer tse ngata, haholo-holo polyvinyl chloride. E le mokhoa oa karabelo bakeng sa Grignard le li-hydride tsa tšepe. Ho etseng butyrolactone, succinic acid, 1,4-butanediol diacetate. Solvent mekhoeng ea histological. E ka sebelisoa tlas'a Molao oa Lijo, Lithethefatsi le Litlolo oa Federal bakeng sa ho etsa lintho bakeng sa ho paka, ho tsamaisa, kapa ho boloka lijo haeba bongata bo setseng bo sa fete 1.5% ea filimi: Fed. Regist. 27, 3919 (La 25 Mmesa, 1962).
Tetrahydrofuran e sebediswa haholoholo (80%) ho etsa polytetramethylene ether glycol, polymer ya motheo e sebediswang haholoholo tlhahisong ya difaeba tsa elastomeric (mohlala, spandex) hammoho le polyurethane le polyester elastomers (mohlala, letlalo la maiketsetso, mabili a skateboard). Karolo e setseng (20%) e sebediswa ditshebedisong tsa di-solvent (mohlala, di-samente tsa diphaephe, dikhomaretsi, enke ya ho hatisa, le theipi ya makenete) mme e le tharollo ya karabelo ho di-syntheses tsa dikhemikhale le tsa meriana.
