Tetrahydrofuran

Tetrahydrofuran, ipfupiso thf, is heterocyclic organic compand. Ndezvemakirasi eAther, ndiyo inonhuhwirira yemhando yeFuran yakazara yeHydrogenation chigadzirwa.

Tetrahydrofuran ndeimwe yeiyo yakasimba polar etini. Iyo inoshandiswa sepakati polar solvent mumakemikari maitiro uye kubviswa. Iyo isina ruvara isina ruvara mvura pamhepo tembiricha uye ine shuwa yakafanana neEther. Nyorovesa mumvura, ethanol, ethanol, acetone, makemikaribook benzone uye mamwe manyorerwo organic sols, anozivikanwa se "Universal Solvent". Pamhepo tembiricha uye mvura inogona kuve yakakanganisika, imwe isiri pamutemo bhizinesi kushandisa iyi pfungwa kuTetrahydrouran regent mvura purofiti. Nekuda kweiyo tsika yeTF kuumba peroxides mukuchengetedza, antioxidant bht inowanzowedzerwa kune zvigadzirwa zveindasitiri. Zvinyoro zvemukati ≦ 0,2%. Iyo ine maitiro ekudziya akaderera, akaderera anovhara point uye fluidity yakanaka.

Makemikari Zvivakwa:isina ruvara inojekeswa mvura, ine ether scent. Yakavhenganiswa nemvura, doro, ketone, benzene, ester, ether, ether, uye hydrocarbons.

Zvikuru zvikumbiro:

1. Zvishandiso zvezvinyorwa zveSpandex synthesis Reaction:

Tetrahydrofuran pachayo inogona kuve yePolycendenation (neCationic mhete-kuvhura Repossmerization) muPolytetramethyle ether diol (ptmeg), zvakare inozivikanwa seTetrahydrouran homopolyl. Ptmeg uye toluene diisocyanate (TDI) yakagadzirwa nekupfeka kupokana, kuramba mafuta, kuita kwekudziya kwekushisa, simba rakanyanya rejira rakakosha; Vimba Polyether Polyester elaster zvinyorwa zvakagadzirirwa neDimethyl terefhthalate uye 1, 4-butaneduol. Ptmeg ine hama inosemesa ya2000 uye P-methylene bis (4-phenyl) diisocyanate (MDI) kugadzira pillerthane fiber (spandex fiber), yakakosha rabha uye chimwe chinhu chakakosha kuunganidza zvinhu zvisina kunaka. Iko kunonyanya kukosha kushandiswa kweTH ndeye kugadzirwa kwePTMEG. Sekureva kwehurongwa hwakaoma, anenge 80% yeiyo Global THF inoshandiswa kugadzirwa kwePTMEG, uye ptmeg inonyanya kushandiswa kugadzirwa kweSpandex fiber.

2. Solvent nekuita kwakanaka kuita:

Tetrahydrofuran yakashandiswa zvakanyanya solvent, kunyanya yakakodzera kupaza PVC, polyvinylide chloride danda rakakora uye rakajeka. Solvent yeTape Coating, PVC Surches Coating, Kuchenesa PVC Repelet, Cellast Consurethane Coatings, kuungana, Inks, Inks

3. Inoshandiswa seyakagadzirwa zvigadzirwa zve organic synthesis senge mishonga mishonga:

Pakugadzirwa kweTetrahydrothotihomene, 2.3- Dichlorotetrahdrofuran, valerolactone, butyl lactone and pyrrodidone. Muindasitiri yemishonga, inoshandiswa mune synthesis yekoshingaira, rifumycin, progesterone uye mamwe mahormone madhiragi. Tetrahydrotiophefenool inogadzirwa neHydrogen Sulfide kurapwa, iyo inogona kushandiswa sezvinonhuwira mumugodhi mune mafuta gasi (chiratidzo chehunhu (uye zvakare solvent solvent muindasitiri yemishonga.

4. Zvimwe zvinoshandiswa:

Chromatographic solvent (gel permegraphy chromato) Nyika iri kuwedzera, uye kudiwa kweTetrahydrouron kunoratidza zvakare kukurumidza kukura maitiro.

Njodzi:Tetrahydrofuran ndezvekirasi 3.1 Inonetlamble Liquid neyakaderera flash point, inopenya inogona kuumba musanganiswa wekuputika neyekuputika, Chisikwa chayo chakanyanya kuchenesa ndechimwe njodzi yekuchengetedza. Iyo huru yekuchengetedza kunetsekana ne ths inoumbwa inononoka yekuumbwa zvakanyanya kuputika organic peroxides kana yakavhurwa nemhepo. Kuti uderedze njodzi iyi, otengerhwa zvinhu zvinowanzowedzerwa ne2, 6-di-tert-butylp-cresol (bhish) yekugadzira organic peroxides. Panguva imwecheteyo, THF haifanire kuomeswa nekuti organic peroxides zvichave yakaomeswa mukurara zvakasara.

Operation Kuchera:kuvharwa kushanda, yakazara mhepo. Vashandisi vanofanirwa kudzidziswa zvakanyanya uye vanoteerera zvakanyatsotevedzera maitiro ekushanda. Zvinokurudzirwa kuti vashandiridzi vanopfeka dzidziso yefirita yegasi (hafu yemask), magirazi ekudzivirira anodzivirira, zvipfeko zveanti-static, uye rubber magurovhosi ekudzivirira mafuta. Ramba kure nemoto, kupisa kupisa, hapana kuputa pabasa. Shandisa kuputika-chiratidzo ventilation system nemidziyo. Dzivirira mupfudze kubva pakupukunyuka mumhepo yebasa. Dzivisa kusangana nevehudhiyo, acids uye zvigadziko. Chiyero chinoyerera chinofanira kudzorwa panguva yekuzadza, uye panofanirwa kuve nechishandiso chivakwa chekudzivirira magetsi ekuwedzera. Pakubata, kujekesa uye kusunungura kunofanirwa kuitwa kuti udzivise kukuvadza kurongedza nemidziyo. Yakarongedzwa nemhando dzakasiyana-siyana uye huwandu hwemidziyo yemoto uye leakge emergency yekurapa ekurapa michina. Mudziyo usina chinhu unogona kunge uine zvinokuvadza.

Kuchengetedza Kuchengetedza:Kazhinji iyo commodity ine inhibitor. Chengetedza muchitoro chinotonhorera, chakavanzika. Ramba kure nemoto uye kupisa. Tembiricha yeiyo imba yekuchengetera haifanirwe kupfuura 30 ×. Iyo package inofanira kusungwa uye isingaonekwe nemhepo. Inofanira kuchengetwa zvakasiyana kubva kuna Horodizers, acids negedhi, uye haafanire kusanganiswa. Kuputika-chiratidzo chakavhenekwa uye nzvimbo dzekuvira dzinogamuchirwa. Usashandise michina michina uye maturusi ayo anowanzo kuvezwa. Nzvimbo yekuchengetera inofanira kuve yakashongedzerwa neyekudzima emergency ekurapa michina uye yakakodzera kubata zvinhu.
