Tetrahydrofuran/CAS:109-99-9

Tetrahydrofuran, wanda aka taƙaita shi da THF, wani sinadari ne na halitta mai kama da juna. Kasancewarsa a cikin ajin ether, samfurin hydrogen ne mai cikakken sinadarin furotin mai ƙamshi. Tetrahydrofuran yana ɗaya daga cikin mafi ƙarfi na polar ethers, wanda ake amfani da shi azaman matsakaicin sinadarin polarity a cikin halayen sinadarai da cirewa. Ruwa ne mara launi da canzawa a zafin ɗaki, tare da ƙamshi iri ɗaya da ether. An narkar da shi a cikin yawancin sinadarai na halitta kamar ruwa, ethanol, ether, acetone, da benzene, ana kiransa "mai narkewa na duniya". A zafin ɗaki, ana iya mirgine shi da ruwa kaɗan, kuma wasu 'yan kasuwa na reagents ba bisa ƙa'ida ba suna amfani da wannan don samun riba mai yawa ta hanyar haɗa tetrahydrofuran reagent da ruwa. Saboda yanayin THF na samar da peroxides yayin ajiya, samfuran masana'antu gabaɗaya suna ƙara BHT mai hana tsufa. Yawan danshi ≤ 0.2%. Yana da halaye na ƙarancin guba, ƙarancin tafasa, da kuma kyakkyawan ruwa.

1.spandex synthesis reaction na kayan da aka ƙera tetrahydrofuran da kanta na iya zama polycondensation (ta hanyar cation initiated ring-opening polymerization) zuwa polytetramethylene ether glycol (PTMEG), wanda kuma aka sani da tetrahydrofuran homopolymerization ether. PTMEG da toluene diisocyanate (TDI) da aka yi da roba masu jure wa abrasion, masu jure wa mai, da ƙarancin zafin jiki, da ƙarfi mai yawa na roba na musamman; kuma tare da dimethyl terephthalate da 1,4-butanediol da aka yi da kayan polyether polyester elastomer. Matsakaicin nauyin kwayoyin PTT shine 2,000. Nauyin kwayoyin halitta na PTMEG 2000 da p-methylene bis (4-phenyl) diisocyanate (MDI) da aka yi da zare na roba na polyurethane (spandex, SPANDEX fiber), roba na musamman da wasu kayan shafa na musamman. THF shine mafi mahimmancin amfani da ake amfani da shi don samar da PTMEG, bisa ga ƙididdiga masu tsauri, ana amfani da fiye da kashi 80% na THF na duniya don samar da PTMEG, da PTMEG, da PTMEG, da PTMEG, da PTMEG, da PTMEG, da PTMEG, da PTMEG, da PTMEG. Ana amfani da PTMEG, da PTMEG galibi don samar da zare na spandex na roba.
2. Tetrahydrofuran wani sinadari ne mai kyau wanda ake amfani da shi sosai, musamman don narke PVC, polyvinylidene chloride da butylaniline, wanda ake amfani da shi sosai azaman sinadari don rufin saman, rufin hana lalata, tawada na bugawa, tef da murfin fim don electro-Chemicalbook Aluminum Plating Liquid za a iya sarrafa kauri na aluminum da Haske ba tare da izini ba. Rufin tef ɗin Magnetic, murfin saman PVC, tsaftace reactor na PVC, cire fim ɗin PVC, murfin cellophane, tawada na buga filastik, murfin polyurethane na thermoplastic, abubuwan narkewa don manne, ana amfani da su sosai a cikin rufin saman, murfin kariya, tawada, abubuwan cirewa da wakilan maganin saman don fata ta roba.
3. Ana amfani da shi azaman kayan aiki na halitta don haɗakar sinadarai kamar magunguna da ake amfani da su wajen samar da tetrahydrothiophene, 1.4 - dichloroethane, 2.3 Ana amfani da shi don samar da tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, valerolactone, butyrolactone da pyrrolidone. A masana'antar magunguna, ana amfani da shi don haɗa tari, Rifamycin, progesterone da wasu magungunan hormones. Tetrahydrothiophenol ana samar da shi ta hanyar maganin hydrogen sulfide, wanda za'a iya amfani da shi azaman ƙanshi a cikin iskar gas (ƙarin ganowa), kuma shine babban mai narkewa a masana'antar magunguna.
4. Sauran Amfani: Maganin chromatographic (gel permeation chromatography), wanda ake amfani da shi don dandanon iskar gas, maganin solvent don cire acetylene, da kuma masu daidaita haske don kayan polymer. Tare da yawan amfani da tetrahydrofuran, musamman saurin ci gaban masana'antar spandex ta China a cikin 'yan shekarun nan, hakan ya sa buƙatar China ga PTMEG ke ƙaruwa, kuma sakamakon buƙatar tetrahydrofuran shi ma yana ci gaba da ƙaruwa cikin sauri.
