Tetrahydrofuran, kana ichipfupikiswa seTHF, imhando yeheterocyclic organic compound. Iri muboka reether, imhando yehydrogen yakazara kubva ku aromatic compound furan. Tetrahydrofuran ndeimwe ye polar ethers dzakasimba, dzinoshandiswa se medium polarity solvent mumakemikari uye mukubvisa. Imvura isina ruvara uye inoshanduka patembiricha yemumba, ine hwema hwakafanana nehwe ether. Yakanyungudutswa mu organic solvents dzakawanda dzakadai semvura, ethanol, ether, acetone, uye benzene, inonzi "universal solvent". Patembiricha yemumba, inosanganiswa zvishoma nemvura, uye vamwe vatengesi ve reagents zvisiri pamutemo vanoshandisa izvi kuti vawane purofiti yakakura nekusanganisa tetrahydrofuran reagent nemvura. Nekuda kwetsika yeTHF yekugadzira peroxides panguva yekuchengetera, zvigadzirwa zvemaindasitiri zvinowanzo wedzera antioxidant BHT. Hunyoro ≤ 0.2%. Ine hunhu hwehupfu hushoma, kufashaira kwakaderera, uye kuyerera kwakanaka.
Kushandiswa
1. Kugadziriswa kwespandex kwezvinhu zvakagadziriswa tetrahydrofuran pachayo kunogona kuva polycondensation (nekushandiswa kwe cation ring-opening polymerization) kuita polytetramethylene ether glycol (PTMEG), inozivikanwawo se tetrahydrofuran homopolymerization ether. PTMEG ne toluene diisocyanate (TDI) zvakagadzirwa ne rabha dzisingakuvadzi, dzisingakuvadzi mafuta, dzine tembiricha yakaderera, dzine simba guru rerubha dzakakosha; uye ne dimethyl terephthalate ne 1,4-butanediol zvakagadzirwa nezvinhu zve block polyether polyester elastomer. Huwandu hwe PTT hunosvika 2,000. Huwandu hwemamorekuru e2000 PTMEG uye p-methylene bis (4-phenyl) diisocyanate (MDI) yakagadzirwa ne polyurethane elastic fibers (spandex, SPANDEX fiber), rabha dzakakosha uye mamwe machira ekushandisa akakosha. THF ndiyo inonyanya kushandiswa pakugadzira PTMEG, zvichienderana nehuwandu hwehuwandu, inopfuura 80% yeTHF yepasi rose inoshandiswa pakugadzira PTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG, nePTMEG. PTMEG, nePTMEG zvinonyanya kushandiswa pakugadzira elastic spandex fibers.
2. Mushonga unonyungudutsa une simba guru tetrahydrofuran mushonga unoshandiswa zvakanyanya, kunyanya pakunyungudutsa PVC, polyvinylidene chloride uye butylaniline, unoshandiswa zvakanyanya semushonga unonyungudutsa pamusoro, unorwisa ngura, inki dzinodhinda, matepi uye jira remafirimu re electro-Chemicalbook Aluminium Plating Liquid inogona kudzora ukobvu hwealuminium nekubwinya. Magnetic tape coating, PVC surface coating, kuchenesa PVC reactor, kubvisa PVC film, cellophane coating, plastic printing ink, thermoplastic polyurethane coating, solvents ye adhesives, inoshandiswa zvakanyanya mu surface coating, protective coating, inks, extractants uye surface treatment agents yedehwe rekugadzira rakagadzirwa.
3. Inoshandiswa sezvinhu zvekugadzira organic synthesis zvakaita semishonga inoshandiswa mukugadzira tetrahydrothiophene, 1.4 - dichloroethane, 2.3 Inoshandiswa kugadzira tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, valerolactone, butyrolactone uye pyrrolidone. Muindasitiri yemishonga, inoshandiswa mukugadzira chikosoro, Rifamycin, progesterone nemimwe mishonga yehormone. Tetrahydrothiophenol inogadzirwa ne hydrogen sulfide treatment, iyo inogona kushandiswa semunhuwi mumafuta (zvinowedzera kuzivikanwa), uye ndiyowo solvent huru muindasitiri yemishonga.
4. Mamwe Mashandisirwo: Chromatographic solvent (gel permeation chromatography), inoshandiswa pakugadzira flavour yegesi rechisikigo, solvent yekubvisa acetylene, uye light stabilizers yezvinhu zvepolymer. Nekushandiswa kwakakura kwe tetrahydrofuran, kunyanya kukura nekukurumidza kweindasitiri yespandex yeChina mumakore achangopfuura, zviri kuita kuti kudiwa kwePTMEG neChina kuri kuwedzera, uye kudiwa kwe tetrahydrofuran kuri kukura nekukurumidza.
Kurongedza uye Kutumira
180KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Inogona kuendesa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
