1. ʻO Tetrahydrofuran, ka mea maka o ka synthesist spandex, hiki ke polycondensated iā ia iho (wehe ke komo a me ka polymerization hou i hoʻomaka ʻia e cation) i ka poly (tetramethylene ether glycol) (PTMEG), ʻo ia hoʻi ʻo tetrahydrofuran polyether. ʻO PTMEG a me toluene diisocyanate (TDI) i hoʻohana ʻia e hana i nā pale kūikawā me ka pale o ke komo ʻana, ka ʻaila ʻaila, hana maikaʻi haʻahaʻa haʻahaʻa a me ka ikaika kiʻekiʻe, a hana ʻia ka poli poly polyester elastis me ka dimethyl terephthalate a me 1,4-butanediol. Hoʻohana ʻia ʻo PTMEG me ka paukū mole o 2000 a me p-methylene bis (4-phenyl) diisocyanate (MDI) e like me nā mea maka no ka pulupulu polyurethane elastic (spandex fiber), kāpili kūikawā a me kekahi mau pale kumuhana kūikawā. ʻO ka hoʻohana nui o THF e hana iā PTMEG. Wahi a nā helu helu paʻakikī, ʻoi aku ma mua o 80% o THF i ka honua i hoʻohana ʻia e hana PTMEG, a hoʻohana nui ʻia ʻo PTMEG e hana i nā fiber spandex fiber. 2.ʻO Tetrahydrofuran(THF) kahi mea hoʻoheheʻe maikaʻi maʻamau, ʻoi aku ka maikaʻi no ka hoʻopau ʻana i ka PVC, polyvinylidene chloride a me ka butylamine. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻoheheʻe no ka uhi o luna, ka uhi anticorrosive, ka inika paʻi, ka leki a me ka uhi kiʻi ʻoniʻoni. Hiki iā ia ke kāohi i ka mānoanoa a me ka ʻōlinolino o ka papa alumini ke hoʻohana ʻia i ka ʻauʻau plating alumini electroless. Ka uhi uhi, ka uhi o ka ʻili PVC, ka hoʻomaʻemaʻe PVC reactor, ka hoʻoneʻe ʻana i ke kiʻi ʻoniʻoni PVC, ka uhi cellophane, ka inika paʻi palolo, ka uhi thermoplastic polyurethane, mea hoʻoheheʻe lina, hoʻohana ākea ʻia i ka uhi o ka ʻilikai, ka pale pale, ka inika, ʻenekini unuhi a me ka ʻenekiniʻili ʻili synthetic.

3. Hoʻohana ʻia e like me nā mea maka no ka synthetic synthetic e like me nā lāʻau lapaʻau. I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ia e synthesize kebiqing, rifamycin, progesterone a me kekahi mau lāʻau i ʻo ka hormone. Hiki ke hoʻohana ʻia ma ke ʻano he mea ʻala (hoʻohui hoʻohui) i ke kinoea wahie a me ka mea hoʻoheheʻe nui i ka ʻoihana lāʻau.

4. hoʻohana ʻia nā mea hoʻoheheʻe chromatographic no nā hoʻohana ʻē aʻe (gel permeation chromatography) no ke kinoea kūlohelohe, nā mea hoʻoheheʻe hemo acetylene, nā mea hoʻomālamalama kukui polymeric, a me nā mea like ʻole. ke hoʻonui nei ka noi no PTMEG ma Kina i kēlā me kēia lā, a ke hōʻike nei nō hoʻi ka noi no tetrahydrofuran i kahi ulu wikiwiki.

Ka mālama ʻana no ka mālama ʻana: maʻamau, hoʻohui ʻia nā huahana me ka mea hoʻopili polymerization. E hale kūʻai i loko o kahi waihona hoʻoluʻolu a ʻono hoʻi. E mālama mai ke ahi a me nā kumu wela. ʻAʻole iʻoi aku ka nui o ka mahana mālama ma mua o 30 ℃. Pono e sila ʻia ka pūʻulu a ʻaʻole pili i ka ea. Pono e mālama kaʻawale ʻia mai ka oxidant, acid, alkali, a me nā mea ʻē aʻe. Pāpā ʻia ka hoʻohana ʻana i nā pono mīkini a me nā pono hana maʻalahi e hana i nā hunaahi. E hoʻolako pono ʻia kahi e waiho ai me nā lako hana hoʻopulapula leakage a me nā pono kūpono e mālama ai.
