Te Whakamahinga o te Hua:
Whakamahia hei whakarewa me te rauemi mata mō te hanga rauropi

Ko te Tetrahydrofuran, he whakarāpopototanga THF, he matū rauropi heterocyclic. Nō te rōpū ether, ā, ko te hua hauwai katoa o te matū kakara furan. Ko te Tetrahydrofuran tētahi o ngā ether polar kaha rawa atu. Ka whakamahia hei whakarewa polar reo i roto i te tauhohenga matū me te tango. He wai pūngāwerewere kore tae i te pāmahana rūma, ā, he rite te kakara ki te diethyl ether. Ka wairewa ki te wai, te etanoru, te ether, te acetone, te benzene me ētahi atu whakarewa rauropi, e mōhiotia ana ko te "whakarewa whānui". Ka taea te whakaranu wāhanga ki te wai i te pāmahana rūma, koia te take e nui ai ngā hua o ētahi kaihoko matū ture kore mā te whakaranu i te matū tetrahydrofuran ki te wai. Nā te mea ka hangaia e te THF ngā peroxide i te wā e rongoa ana, ko te BHT antioxidant te nuinga o te wā ka tāpirihia ki ngā hua ahumahi. He iti iho i te 0.2% te nui o te wai. He iti te paitini, he iti te kohua me te pai o te rere.
I tēnei wā, ko ngā kaihanga nui o te tetrahydrofuran i roto i te motu ko BASF China, Dalian Yizheng (DCJ), Shanxi Sanwei, Sinochem International, me Petrochina Qianguo Refinery, me ētahi atu, ā, ko ētahi atu tipu PBT anō hoki e whakaputa ana i ētahi wāhanga o ngā hua taha. Ko ngā taupū hoko a LyondellBasell Industries i te United States me Europe ko: te parakore 99.90%Chemicalbook, chroma (APHA) 10, te makuku 0.03%, THF hydroperoxide 0.005%, te poke katoa 0.05%, me te aukati waikura 0.025% ~ 0.035%. I roto i te umanga polyurethane, ko te whakamahinga nui ko te rauemi monomer mō te polytetrahydrofuranediol (PTMEG), koinei hoki tētahi o ngā whakamahinga matua o te THF.

Ngā whakamahinga matua:
Ko te kaupapa matua
1. Ko te rauemi mata o te hanganga o te muka polyurethane tetrahydrofuran ka taea te whakamahi i te polycondensation (cationic initiated ring-opening repolymerization) ki roto i te polytetramethylene ether diol (PTMEG), e mōhiotia ana ko te tetrahydrofuran homopolyether. Ka hangaia te PTMEG me te TOLuene diisocyanate (TDI) hei rapa motuhake he pai te ātete ki te kakahu, te ātete ki te hinu, te mahi pāmahana iti me te kaha teitei. I whakaritea te elastomer polyester poraka polyether ki te dimethyl terephthalate me te 1, 4-butanediol. Ko ngā muka polyurethane elastic (SPANDEX, SPANDEX), te rapa motuhake me ētahi paninga motuhake ka hangaia mai i te 2000 PTMEG me te p-methylene bis (4-phenyl) diisocyanate (MDI). Ko te whakamahinga nui o te THF ko te hanga PTMEG. E ai ki ngā tatauranga whānui, neke atu i te 80% o te THF o te ao e whakamahia ana hei hanga PTMEG, ko te PTMEG ia e whakamahia ana hei hanga muka spandex elastic.
2. He whakarewa pai te Tetrahydrofuran e whakamahia whānuitia ana, he tino pai mō te whakarewa i te PVC, te polyvinylidene chloride me te butaniline. He whānuitia te whakamahinga hei whakarewa mō te paninga mata, te paninga ārai-waikura, te waituhi tā, te rīpene aukume me te paninga kiriata. Paninga rīpene aukume, paninga mata PVC, TE HOROI i te tauhohenga PVC, te tango i te kiriata PVC, te paninga cellophane, te waituhi tā kirihou, te paninga polyurethane thermoplastic, te whakarewa mō ngā piri, he whānuitia te whakamahinga i roto i ngā paninga mata, ngā paninga tiaki, ngā waituhi, ngā tangohanga me ngā kaihoko whakaoti mata hiako hangai.
3. Whakamahia hei rauemi mata mō te hanga matū waro pērā i ngā rongoā mō te hanga tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, pentolactone, butyllactone me te pyrrolidone, me ētahi atu. I roto i te umanga rongoā, ka whakamahia mō te hanga kepidine, rifamycin, progesterone me ētahi rongoā homoni. Ko te Tetrahydrothiophenol, e whakaputaina ana mā te maimoatanga hauwai sulfide, ka taea te whakamahi hei kaihoko kakara (tāpiri tautuhi) i roto i te hau wahie, ā, koia hoki te whakarewa matua i roto i te umanga rongoā.
4. Ētahi atu whakamahinga o ngā whakarewa chromatography (gel permeation chromatography), e whakamahia ana mō te reka o te hau māori, te whakarewa tango acetylene, ngā rauemi polymer, pērā i te whakaū rama. Nā te whānui o te whakamahinga o te tetrahydrofuran, inā koa te tere o te tipu o te umanga spandex i Haina i ngā tau tata nei, kei te piki haere te tono mō te PTMEG i Haina i ia rā, ā, e whakaatu ana hoki te tono mō te tetrahydrofuran i tētahi ia tere o te tipu.
