Kushandiswa Kwechigadzirwa:
Inoshandiswa se solvent uye sezvinhu zvakagadziriswa pakugadzira organic synthesis

Tetrahydrofuran, kana kuti THF muchidimbu, imhando ye heterocyclic organic compound. Iri muboka re ether uye ndiyo hydrogenation yakazara ye aromatic compound furan. Tetrahydrofuran ndeimwe ye polar ether yakasimba. Inoshandiswa se medium polar solvent mu chemical reaction uye extraction. Imvura isina ruvara inoshanduka patembiricha yemumba uye ine hwema hwakafanana ne diethyl ether. Inonyungudika mumvura, ethanol, ether, acetone, Chemicalbook benzene nedzimwe organic solvents, inozivikanwa se "universal solvent". Inogona kusanganiswa zvishoma nemvura patembiricha yemumba, ndosaka vamwe vatengesi ve reagents zvisiri pamutemo vachiita purofiti yakakura nekusanganisa tetrahydrofuran reagent nemvura. Sezvo THF ichiwanzogadzira peroxides mukuchengetedza, antioxidant BHT inowanzowedzerwa muzvigadzirwa zvemaindasitiri. Huremu hwemvura huri pasi pe0.2%. Ine hunhu hwechepfu shoma, kufashaira kwakaderera uye kuyerera kwakanaka.
Parizvino, vagadziri vakuru ve tetrahydrofuran vemuno vanosanganisira BASF China, Dalian Yizheng (DCJ), Shanxi Sanwei, Sinochem International, nePetrochina Qianguo Refinery, nezvimwewo, uye mamwe mafekitori ePBT anogadzirawo chikamu chezvigadzirwa. Ma indekisi ekutengesa eLyondellBasell Industries muUnited States neEurope ndeaya: purity 99.90% Chemicalbook, chroma (APHA) 10, moisture 0.03%, THF hydroperoxide 0.005%, total discharge 0.05%, uye oxidation inhibitor 0.025% ~ 0.035%. Muindasitiri ye polyurethane, kushandiswa kwakakosha ndeye monomer material ye polytetrahydrofuranediol (PTMEG), inova imwe yekushandiswa kukuru kweTHF.

Mashandisirwo makuru:
Chinangwa chikuru
1. Zvinhu zvakagadziriswa zve polyurethane fiber tetrahydrofuran zvinogona kuva polycondensation (cationic initiated ring-opening repolysis) mu polytetramethylene ether diol (PTMEG), inozivikanwawo se tetrahydrofuran homopolyether. PTMEG neTOLuene diisocyanate (TDI) zvinogadzirwa kuita rabha rakakosha rine resistance yakanaka yekupfeka, resistance yemafuta, tembiricha yakaderera uye simba rakakwirira. Block polyester elastomer yakagadzirwa ne dimethyl terephthalate uye 1, 4-butanediol. Polyurethane elastic fibers (SSPANDEX, SPANDEX), rabha rakakosha uye mamwe macoatings akakosha anogadzirwa kubva ku2000 PTMEG uye p-methylene bis (4-phenyl) diisocyanate (MDI). Kushandiswa kwakakosha kweTHF kugadzira PTMEG. Zvichienderana nehuwandu hwe rough, inopfuura 80% yeTHF pasi rose inoshandiswa kugadzira PTMEG, nepo PTMEG ichinyanya kushandiswa kugadzira elastic spandex fiber.
2. Tetrahydrofuran chinhu chinonyungudutsa chinoshandiswa zvakanyanya, chakakodzera kunyungudutsa PVC, polyvinylidene chloride uye butaniline. Chinoshandiswa zvakanyanya sechinonyungudutsa pamusoro pechinonyungudutsa, chinodzivirira ngura, inki yekudhinda, tepi yemagineti uye chinonyungudutsa firimu. Chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa pamusoro pechinonyungudutsa, chinonyungudutsa, uye chinonyungudutsa pamusoro pechinonyungudutsa.
3. Inoshandiswa sezvinhu zvekugadzira zvinhu zvakasikwa zvakaita semishonga yekugadzira tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, pentolactone, butyllactone uye pyrrolidone, nezvimwewo. Muindasitiri yemishonga, inoshandiswa kugadzira kepidine, rifamycin, progesterone nemimwe mishonga yehomoni. Tetrahydrothiophenol, inogadzirwa nehydrogen sulfide treatment, inogona kushandiswa sechinhu chinonhuhwirira (chinowedzerwa pakuziva) mugasi remafuta uye ndiyo inonyanya kushandiswa muindasitiri yemishonga.
4. Mamwe mashandisirwo e chromatographic solvents (gel permeation chromatography), anoshandiswa pakuravira kwegasi rechisikigo, acetylene extraction solvent, polymer materials, akadai se light stabilizer. Nekushandiswa kwakakura kwe tetrahydrofuran, kunyanya kukura nekukurumidza kweindasitiri ye spandex muChina mumakore achangopfuura, kudiwa kwePTMEG muChina kuri kuwedzera zuva nezuva, uye kudiwa kwe tetrahydrofuran kunoratidzawo kukura nekukurumidza.
