Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe a me ka mea maka no ka synthesis organik

ʻO Tetrahydrofuran, i hoʻopōkole ʻia ʻo THF, he hui organik heterocyclic. No ka hui ether ia a ʻo ia ka huahana hydrogenation piha o ka hui ʻala furan. ʻO Tetrahydrofuran kekahi o nā ether polar ikaika loa. Hoʻohana ʻia ia ma ke ʻano he solvent polar waena i ka hopena kemika a me ka unuhi ʻana. He wai hoʻoheheʻe kala ʻole ia ma ka mahana o ka lumi a he ʻala like me ka diethyl ether. Hoʻoheheʻe ʻia i ka wai, ethanol, ether, acetone, Chemicalbook benzene a me nā solvent organik ʻē aʻe, i ʻike ʻia ʻo ka "solvent universal". Hiki ke hoʻohuihui hapa ʻia me ka wai ma ka mahana o ka lumi, ʻo ia ke kumu e loaʻa ai i kekahi mau mea kūʻai aku reagent kū ʻole i ke kānāwai ka waiwai nui ma ka hui ʻana i ka reagent tetrahydrofuran me ka wai. ʻOiai ʻo THF ke ʻano e hana i nā peroxides i ka mālama ʻana, hoʻohui pinepine ʻia ka antioxidant BHT i nā huahana ʻoihana. ʻOi aku ka liʻiliʻi o ka wai ma mua o 0.2%. Loaʻa iā ia nā ʻano o ka haʻahaʻa haʻahaʻa, ka paila haʻahaʻa a me ka wai maikaʻi.
I kēia manawa, ʻo nā mea hana nui o ka tetrahydrofuran kūloko e komo pū ana me BASF Kina, Dalian Yizheng (DCJ), Shanxi Sanwei, Sinochem International, a me Petrochina Qianguo Refinery, a me nā mea ʻē aʻe, a ʻo kekahi mau hale hana PBT ʻē aʻe e hana pū ana i kahi hapa o nā huahana ʻaoʻao. ʻO nā helu kūʻai aku a LyondellBasell Industries ma ʻAmelika Hui Pū ʻIa a me ʻEulopa: maʻemaʻe 99.90%Chemicalbook, chroma (APHA) 10, moisture 0.03%, THF hydroperoxide 0.005%, total impurity 0.05%, a me ka oxidation inhibitor 0.025% ~ 0.035%. I ka ʻoihana polyurethane, ʻo ka hoʻohana nui loa he mea monomer no ka polytetrahydrofuranediol (PTMEG), ʻo ia kekahi o nā hoʻohana nui o THF.

Nā hoʻohana nui:
ʻO ke kumu nui
1. Hiki i ka mea maka o ka synthesis o ka polyurethane fiber tetrahydrofuran ke polycondensation (cationic initiated ring-opening repolymerization) i loko o ka polytetramethylene ether diol (PTMEG), i ʻike ʻia hoʻi ʻo tetrahydrofuran homopolyether. Hana ʻia ka PTMEG a me TOLuene diisocyanate (TDI) i loko o ka rubber kūikawā me ke kūpaʻa maikaʻi o ka ʻaʻahu, ke kūpaʻa ʻaila, ka hana haʻahaʻa haʻahaʻa a me ka ikaika kiʻekiʻe. Ua hoʻomākaukau ʻia ka block polyether polyester elastomer me ka dimethyl terephthalate a me 1, 4-butanediol. Hana ʻia nā fibers elastic polyurethane (SPANDEX, SPANDEX), ka rubber kūikawā a me kekahi mau uhi kumu kūikawā mai 2000 PTMEG a me p-methylene bis (4-phenyl) diisocyanate (MDI). ʻO ka hoʻohana nui ʻana o THF ʻo ia ka hana ʻana i ka PTMEG. Wahi a nā helu helu, ʻoi aku ma mua o 80% o THF ma ka honua e hoʻohana ʻia e hana i ka PTMEG, ʻoiai ʻo PTMEG ka mea nui e hoʻohana ʻia e hana i ka fiber spandex elastic.
2. He mea hoʻoheheʻe maikaʻi ʻo Tetrahydrofuran i hoʻohana pinepine ʻia, kūpono loa no ka hoʻoheheʻe ʻana i ka PVC, polyvinylidene chloride a me ka butaniline. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻoheheʻe no ka uhi ʻili, ka uhi anti-corrosion, ka ʻīnika paʻi, ka lipine magnetic a me ka uhi kiʻiʻoniʻoni. Uhi lipine magnetic, uhi ʻili PVC, HOʻOMAʻEMAʻE PVC reactor, wehe ʻana i ka kiʻiʻoniʻoni PVC, uhi cellophane, ʻīnika paʻi plastik, uhi polyurethane thermoplastic, mea hoʻoheheʻe no nā mea hoʻopili, hoʻohana nui ʻia i nā uhi ʻili, nā uhi pale, nā ʻīnika, nā mea unuhi a me nā mea hoʻopau ʻili ʻili synthetic.
3. Hoʻohana ʻia ma ke ʻano he mea maka no ka synthesis organik e like me nā lāʻau lapaʻau no ka hana ʻana o tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, pentolactone, butyllactone a me pyrrolidone, a pēlā aku. I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia no ka synthesis o kepidine, rifamycin, progesterone a me kekahi mau lāʻau hormonal. ʻO Tetrahydrothiophenol, i hana ʻia e ka mālama ʻana o ka hydrogen sulfide, hiki ke hoʻohana ʻia ma ke ʻano he mea ʻala (mea hoʻohui ʻike) i loko o ke kinoea wahie a ʻo ia hoʻi ka mea hoʻoheheʻe nui i ka ʻoihana lāʻau lapaʻau.
4. Nā hoʻohana ʻē aʻe o nā mea hoʻoheheʻe chromatographic (gel permeation chromatography), hoʻohana ʻia no ka ʻono kinoea kūlohelohe, ka mea hoʻoheheʻe acetylene, nā mea polymer, e like me ka mea hoʻopaʻa māmā. Me ka hoʻohana ākea o ka tetrahydrofuran, ʻoi aku ka ulu wikiwiki o ka ʻoihana spandex ma Kina i nā makahiki i hala iho nei, ke piʻi nei ke koi no PTMEG ma Kina i kēlā me kēia lā, a ke hōʻike pū nei ke koi no ka tetrahydrofuran i kahi ʻano ulu wikiwiki.
