Ejiri ya mee ihe dị ka ihe mgbaze na ihe eji emepụta ihe maka njikọ organic

Tetrahydrofuran, nke a kpọrọ THF, bụ ihe mejupụtara ihe ndị na-emepụta ihe ndị na-adịghị mma. Ọ bụ nke otu ether ma bụrụkwa ngwaahịa hydrogenation zuru oke nke ihe na-esi ísì ụtọ nke furan. Tetrahydrofuran bụ otu n'ime polar ether kachasị ike. A na-eji ya dị ka ihe mgbaze polar ọkara na mmeghachi omume kemịkalụ na mwepụta. Ọ bụ mmiri na-adịghị agbanwe agbanwe na okpomọkụ ụlọ ma nwee isi yiri nke diethyl ether. A na-agbaze na mmiri, ethanol, ether, acetone, Chemicalbook benzene na ihe mgbaze organic ndị ọzọ, nke a maara dị ka "ihe mgbaze zuru ụwa ọnụ". Enwere ike iji ya na mmiri gwakọta ya na okpomọkụ ụlọ, nke bụ ya mere ụfọdụ ndị na-ere ihe ndị na-emepụta ihe ndị na-adịghị mma na-enweta nnukwu uru site na ịgwakọta ihe ndị na-emepụta ihe na tetrahydrofuran na mmiri. Ebe ọ bụ na THF na-emepụta peroxides na nchekwa, a na-agbakwụnyekarị ihe na-egbochi BHT na ngwaahịa ụlọ ọrụ mmepụta ihe. Ọdịnaya mmiri erughị 0.2%.

Ugbu a, ndị na-emepụta tetrahydrofuran n'ime obodo bụ BASF China, Dalian Yizheng (DCJ), Shanxi Sanwei, Sinochem International, na Petrochina Qianguo Refinery, wdg, yana ụfọdụ ụlọ ọrụ PBT ndị ọzọ na-emepụta akụkụ nke ngwaahịa ndị ọzọ. Ndepụta ahịa nke ụlọ ọrụ LyondellBasell Industries na United States na Europe bụ: ịdị ọcha 99.90% Chemicalbook, chroma (APHA) 10, mmiri mmiri 0.03%, THF hydroperoxide 0.005%, ọcha zuru oke 0.05%, na ihe mgbochi oxidation 0.025% ~ 0.035%. Na ụlọ ọrụ polyurethane, ojiji kachasị mkpa bụ dị ka ihe monomer maka polytetrahydrofuranediol (PTMEG), nke bụkwa otu n'ime ojiji bụ isi nke THF.

Ojiji ndị bụ isi:
Isi ihe mere e ji mee ya
1. Ihe e ji emepụta eriri polyurethane tetrahydrofuran nwere ike ịbụ polycondensation (cationic initiated ring-opening repolymerization) ka ọ bụrụ polytetramethylene ether diol (PTMEG), nke a makwaara dị ka tetrahydrofuran homopolyether. A na-eme PTMEG na TOLuene diisocyanate (TDI) ka ọ bụrụ roba pụrụ iche nke nwere ezigbo nguzogide iyi, iguzogide mmanụ, arụmọrụ okpomọkụ dị ala na ike dị elu. Ejiri dimethyl terephthalate na 1, 4-butanediol kwadebe elastomer polyether polyester. Ejiri eriri elastic polyurethane (SPANDEX, SPANDEX), roba pụrụ iche na ụfọdụ mkpuchi ebumnuche pụrụ iche mee site na 2000 PTMEG na p-methylene bis (4-phenyl) diisocyanate (MDI). Ojiji kachasị mkpa nke THF bụ imepụta PTMEG. Dịka ọnụ ọgụgụ siri ike si kwuo, a na-eji ihe karịrị 80% nke THF n'ụwa emepụta PTMEG, ebe a na-ejikarị PTMEG emepụta eriri spandex elastic.
2. Tetrahydrofuran bụ ezigbo ihe mgbaze a na-ejikarị eme ihe, ọkachasị maka ịgbaze PVC, polyvinylidene chloride na butaniline. A na-eji ya eme ihe dị ka ihe mgbaze maka mkpuchi elu, mkpuchi mgbochi ire ere, ink mbipụta, teepu magnet na mkpuchi ihe nkiri. Mkpuchi teepu magnet, mkpuchi elu PVC, NHICHA PVC reactor, iwepụ ihe nkiri PVC, mkpuchi cellophane, ink mbipụta plastik, mkpuchi polyurethane thermoplastic, ihe mgbaze maka ihe nrapado, a na-ejikarị ya eme ihe n'elu mkpuchi elu, mkpuchi nchebe, ink, ihe mwepụ na ihe ndị na-emecha elu akpụkpọ anụ sịntetik.
3. A na-eji ya eme ihe dịka ihe eji emepụta ihe ndị sitere n'okike dịka ọgwụ maka imepụta tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, pentolactone, butyllactone na pyrrolidone, wdg. N'ụlọ ọrụ ọgwụ, a na-eji ya eme ihe maka imepụta kepidine, rifamycin, progesterone na ụfọdụ ọgwụ homonụ. Tetrahydrothiophenol, nke a na-emepụta site na ọgwụgwọ hydrogen sulfide, enwere ike iji ya mee ihe dị ka ihe na-esi ísì (ihe mgbakwunye njirimara) na gas mmanụ ọkụ ma bụrụkwa ihe mgbaze bụ isi na ụlọ ọrụ ọgwụ.
4. Ojiji ndị ọzọ nke ihe mgbaze chromatographic (gel permeation chromatography), nke e ji eme ihe maka ụtọ gas eke, ihe mgbaze acetylene, ihe polymer, dị ka ihe na-eme ka ìhè sie ike. Site na ojiji sara mbara nke tetrahydrofuran, karịsịa mmụba ngwa ngwa nke ụlọ ọrụ spandex na China n'afọ ndị na-adịbeghị anya, ọchịchọ maka PTMEG na China na-amụba kwa ụbọchị, ọchịchọ maka tetrahydrofuran na-egosikwa usoro uto ngwa ngwa.
