Zvigadzirwa uye Kugadzikana:
1.Colorless transparent liquid ine ether-yakafanana hwema.Kusanganiswa nemvura.Iyo azeotropic musanganiswa nemvura inogona kunyungudutsa cellulose acetate uye caffeine alkaloids, uye kunyungudika kuita kuri nani pane iyo tetrahydrofuran chete.General organic solvents senge ethanol, ether, aliphatic hydrocarbons, anonhuwirira hydrocarbons, chlorinated hydrocarbons, nezvimwe zvinogona kunyungudika mutetrahydrofuran.Zviri nyore kusanganisa neoxidation mumhepo kugadzira inoputika peroxide.Haina-corrosive kune simbi, uye inoparadza kune akawanda epurasitiki nemarabha.Nekuda kweiyo yekubikira, flash point yakadzikira, nyore kubata moto pakamuri tembiricha.Okisijeni mumhepo panguva yekuchengetedza inogona kuburitsa peroxide inoputika ine tetrahydrofuran.Peroxides inonyanya kuumbwa muhupo hwechiedza uye anhydrous mamiriro.Naizvozvo, 0.05% ~ 1% yehydroquinone, resorcinol, p-cresol kana ferrous munyu uye zvimwe zvinoderedza zvinhu zvinowanzowedzerwa se antioxidants kuti inhibisa chizvarwa cheperoxide.Ichi chigadzirwa chakaderera chepfu, mushandisi anofanira kupfeka giya rekudzivirira.
2.Kugadzikana: Kugadzikana
3.Zvinhu zvinorambidzwa: Acids, alkali, yakasimba oxidising agents, oksijeni
6.Mamiriro ekudzivisa kusvibiswa: Chiedza, mhepo
7.Polymerization ngozi: Polymerization
Product Application:
1.Iyo inoshandiswa zvakanyanya nekuda kwekunaka kwayo kupinza uye diffusivity kune pamusoro uye mukati me resins.Inoshandiswa seyakanyungudika mufomati reaction, polymerisation reaction, LiAlH4 kudzikisa condensation reaction uye esterification reaction.Kuparara kwepolyvinyl chloride, polyvinylidene chloride uye copolymers yavo inoguma mune yakaderera viscosity mhinduro, iyo inowanzoshandiswa mukugadzirwa kwepamusoro pekuvhara, kuvhara kwekudzivirira, kunamatira uye mafirimu.Inoshandiswawo muinki, pendi stripper, extractant, pamusoro pekurapa kweganda rekugadzira.Ichi chigadzirwa ndeche self-polymerization uye copolymerization, inogona kugadzira polyether mhando polyurethane elastomer.Ichi chigadzirwa chakakosha chemakemikari yakasvibiswa, inogona kugadzirirwa butadiene, nylon, polybutylene glycol ether, γ-butyrolactone, polyvinylpyrrolidone, tetrahydrothiophene nezvimwe zvakadaro.Ichi chigadzirwa chinogona zvakare kushandiswa seyepakati mune organic synthesis semishonga.
2.Tetrahydrofuran inogona kuputsa zvose zvinokonzerwa nehupenyu kunze kwepolyethylene, polypropylene uye fluorine resins, kunyanya kune polyvinyl chloride, polyvinylidene chloride uye butylaniline zvine solubility yakanaka, inoshandiswa zvakanyanya seyakagadziriswa inoshandiswa.
3.Sechinhu chinowanzogadziriswa, tetrahydrofuran yakave yakashandiswa zvakanyanya mumucheka wepamusoro, kuvhara kwekudzivirira, inki, zvinyorwa uye kushandiswa kwepamusoro kweganda rekugadzira.
4.Tetrahydrofuran inokosha yakasvibiswa yekugadzirwa kwepolytetramethylene ether glycol (PTMEEG) uye inonyanya kunyungudutsa yemishonga yemishonga.Inoshandiswa sechinhu chinonyungudutsa chezvisikwa uye zvekugadzira resins (kunyanya vinyl resins), inoshandiswawo mukugadzirwa kwebutadiene, adiponitrile, adip.onnitrileadipic acid,hexanediamine zvichingodaro.
5.Inoshandiswa se solvent, chemical synthesis intermediate, analytical reagent.
Chigadzirwa Chekuchengetedza Notes:
1.Chengetedza munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Tembiricha yekuchengetera zvinhu haifanire kudarika 29°C.
4.Chengetedza mudziyo wakavharwa, kwete kusangana nemhepo.
5.Inofanira kuchengetwa zvakasiyana kubva kune oxidising agents, acids,alkalis, nezvimwewo.uye haifaniri kumbosanganiswa.
6.Adopt kuputika-kuvhenekera chiedza uye zvivako zvemhepo.
7.Kurambidza kushandiswa kwemichina yemagetsi uye zvishandiso zviri nyore kugadzira mazhenje.
8.Nzvimbo yekuchengetera inofanirwa kuve yakashongedzerwa nekudonha kwechimbichimbi michina yekurapa uye yakakodzera pekugara zvinhu.
