Ibicuruzwa byiza nibihamye:
1.Amazi adafite amabara meza afite impumuro nziza ya ether. Ntibisanzwe n'amazi. Uruvange rwa azeotropique n'amazi rushobora gushonga acetate ya selile na alkaloide ya cafeyine, kandi imikorere yo gushonga iruta iya tetrahydrofuran yonyine. Amashanyarazi rusange nka Ethanol, ether, hydrocarbone ya alifatique, hydrocarbone ya aromatique, hydrocarbone ya chlorine, nibindi birashobora gushonga neza muri tetrahydrofuran. Biroroshye guhuza na okiside mu kirere kubyara peroxide iturika. Ntabwo yangirika ku byuma, kandi irashobora kwangirika kuri plastiki na rubber nyinshi. Kubera aho bitetse, flash point iri hasi, byoroshye gufata umuriro mubushyuhe bwicyumba. Oxygene mu kirere mugihe cyo kubika irashobora kubyara peroxide iturika hamwe na tetrahydrofuran. Peroxide irashoboka cyane kuboneka imbere yumucyo na anhidrous. Kubwibyo, 0,05% ~ 1% ya hydroquinone, resorcinol, p-cresol cyangwa umunyu wa ferrous nibindi bintu bigabanya akenshi byongerwaho nka antioxydants kugirango ibuze kubyara peroxide. Ibicuruzwa bifite uburozi buke, uyikoresha agomba kwambara ibikoresho birinda.
2. Guhagarara: Birahamye
3.Ibintu bibujijwe: Acide, alkali, ibintu bikomeye bya okiside, ogisijeni
6.Ibisabwa kugirango wirinde guhura: Umucyo, umwuka
7.Polymerisation hazard: Polymerisation
Gusaba ibicuruzwa:
1.Bikoreshwa cyane kubera uburyo bwiza bwo gutembera no gukwirakwira hejuru no imbere imbere. Ikoreshwa nka solvent muburyo bwa reaction, polymerisation reaction, LiAlH4 kugabanya kugabanuka kwa reaction hamwe na esterification reaction. Iseswa rya chloride ya polyvinyl, chloride polyvinylidene hamwe na cololymer zabo bivamo igisubizo gito cyijimye, gikunze gukoreshwa mugukora ibifuniko byo hejuru, gutwikira ibintu, gufatira hamwe na firime. Irakoreshwa kandi muri wino, irangi ryirangi, ikuramo, kuvura hejuru yimpu zubukorikori. Ibicuruzwa ni-polymerisation na copolymerisation, birashobora gukora polyether ubwoko bwa polyurethane elastomer. Iki gicuruzwa nibikoresho byingenzi byimiti, birashobora gutegurwa butadiene, nylon, polybutylene glycol ether, γ-butyrolactone, polyvinylpyrrolidone, tetrahydrothiophene nibindi. Ibicuruzwa birashobora kandi gukoreshwa nkigihe gito muri synthesis organique nkibiyobyabwenge.
2.Tetrahydrofuran irashobora gushonga ibinyabuzima byose bitari polyethylene, polypropilene na fluorine, cyane cyane kuri polyvinyl chloride, polyvinylidene chloride na butylaniline bifite solubile nziza, bikoreshwa cyane nkumuti udasanzwe.
3.Nkumuti usanzwe, tetrahydrofuran yakoreshejwe muburyo bwo gutwikira hejuru, gutwikira kurinda, wino, ibiyikuramo no kuvura uruhu rwubukorikori.
4.Tetrahydrofuran nigikoresho cyingenzi cyo gukora polytetramethylene ether glycol (PTMEEG) nigisubizo gikomeye cyinganda zimiti. Ikoreshwa nkigishishwa cyibisanzwe na sintetike (cyane cyane vinyl resin), ikoreshwa no mubikorwa bya butadiene, adiponitrile, adiponitrileacide adipic,hexanediamine n'ibindi.
5.Bikoreshwa nkibishishwa, synthesis yimiti hagati, isesengura reagent.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Ubushyuhe bwububiko ntibugomba kurenga 29 ° C.
4.Komeza ikintu gifunze, ntabwo ihuye numwuka.
5.Bigomba kubikwa bitandukanye na okiside, aside,alkalis, n'ibindi.kandi ntigomba na rimwe kuvangwa.
6.Kwemeza ibikoresho biturika biturika kandi bihumeka.
7.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
8.Ahantu ho kubika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
