Igiciro cyiza cy'umukora Tetrahydrofuran CAS: 109-99-9

ibisobanuro bigufi:

Tetrahydrofuran (THF) ni amazi adafite ibara, ahindagurika afite impumuro isa n’iya acetone kandi ashobora kuvangwa mu mazi no mu bintu byinshi biyungurura umubiri. Tetrahydrofuran (THF) irashya cyane kandi ishobora kwangirika mu bushyuhe ikaba monoxyde de carbone na dioxyde de carbone. Kubika igihe kirekire iyo bihuye n’umwuka kandi iyo nta antioxydant ihari bishobora gutuma THF ibora ikaba peroxide iturika.

Imikoreshereze ya Tetrahydrofuran

Tetrahydrofuran ikoreshwa mu gukora polymers ndetse no mu buhinzi, imiti, n'ibicuruzwa. Ibikorwa byo gukora bikunze kubaho mu buryo bufunze cyangwa munsi y'ubuyobozi bw'ubuhanga bugabanya ingaruka z'abakozi ku bidukikije no kurekura ibidukikije. THF ikoreshwa kandi nk'umushongi (urugero, gushyira imiyoboro) ushobora gutuma habaho impanuka zikomeye iyo ikoreshejwe ahantu hafunze hatabayeho umwuka uhagije. Nubwo THF isanzwe iboneka mu mpumuro y'ikawa, mu nkoko zitetse, impanuka karemano ntizitezwe ko zishobora guteza akaga gakomeye.
Okiside ya Butylene ikoreshwa nk'umuti wo kwifuriza ibintu ubushyuhe kandi ntivange n'ibindi bintu. Ikoreshwa mu gushimangira ibikomoka kuri peteroli mu bijyanye n'ibara n'imyanda.
Tetrahydrofuran ikoreshwa nk'umusemburo w'ibinure, vinyl, na polymer nyinshi; nk'uburyo bwa Grignard bwo gukora ibikorwa bya organometallic, na hydride by'icyuma; no mu gukora aside succinic na butyrolactone.
Umushongi w’ibinyabutabire byinshi, cyane cyane polyvinyl chloride. Nk'uburyo bwo gukora isesengura rya Grignard na hydride y'icyuma. Mu gukora butyrolactone, aside succinic, 1,4-butanediol diacetate. Umushongi w’ibinyabutabire mu buryo bwa histological. Ushobora gukoreshwa hakurikijwe Itegeko rya Leta rishinzwe ibiribwa, imiti n'ubwiza mu gukora ibintu byo gupakira, gutwara, cyangwa kubika ibiribwa niba igisigaye kitarenze 1.5% by'icyuma: Fed. Regist. 27, 3919 (25 Mata, 1962).
Tetrahydrofuran ikoreshwa cyane cyane (80%) mu gukora polytetramethylene ether glycol, polymer y'ibanze ikoreshwa cyane cyane mu gukora insinga za elastomeric (urugero, spandex) ndetse na polyurethane na polyester elastomer (urugero, uruhu rw'ubukorano, amapine ya skateboard). Ibisigaye (20%) bikoreshwa mu gukoresha solvent (urugero, sima y'imiyoboro, kole, wino icapa, na kaseti ya magnetic) ndetse no nk'umusemburo w'impinduka mu gukora imiti n'imiti.
