Mea Hana Kumukūʻai Maikaʻi Tetrahydrofuran CAS: 109-99-9

wehewehe pōkole:

He wai kala ʻole ʻo Tetrahydrofuran (THF), he wai lele me kahi ʻala ethereal a acetonelike paha a hiki ke hui pū ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik. He mea ʻā loa ʻo Tetrahydrofuran (THF) a hiki ke palaho wela i ke kalapona monoxide a me ke kalapona dioxide. ʻO ka mālama lōʻihi ʻana i ka wā e pili ana me ka ea a me ka nele o kahi antioxidant e hiki ai i ka THF ke palaho i nā peroxides pahū.

Nā noi o Tetrahydrofuran

Hoʻohana ʻia ʻo Tetrahydrofuran i ka hana ʻana i nā polymers a me nā kemika mahiʻai, lāʻau lapaʻau, a me nā waiwai. Hana pinepine ʻia nā hana hana i nā ʻōnaehana pani a i ʻole ma lalo o nā kaohi ʻenekinia e kaupalena ana i ka hōʻike ʻana o ka limahana a me ka hoʻokuʻu ʻana i ke kaiapuni. Hoʻohana ʻia ʻo THF ma ke ʻano he solvent (e laʻa, ka hoʻokomo ʻana i ka paipu) hiki ke hopena i nā hōʻike koʻikoʻi ke hoʻohana ʻia i nā wahi paʻa me ka ʻole o ka ea kūpono. ʻOiai aia maoli ʻo THF i loko o ke ʻala kofe, nā chickpeas i kāpala ʻia, a me ka moa i moʻa ʻia, ʻaʻole i manaʻo ʻia nā hōʻike kūlohelohe e hoʻoweliweli nui.
Hoʻohana ʻia ka butylene oxide ma ke ʻano he fumigant a ʻaʻole i hui pū ʻia me nā hui ʻē aʻe. Hoʻohana ʻia ia e hoʻopaʻa i ka wahie e pili ana i ke kala a me ka hoʻokumu ʻana o ka sludge.
Hoʻohana ʻia ʻo Tetrahydrofuran ma ke ʻano he mea hoʻoheheʻe no nā resins, vinyls, a me nā polymers kiʻekiʻe; ma ke ʻano he mea hana Grignard no nā hana organometallic, a me nā metal hydride; a ma ke ʻano o ka hana ʻana o ka waikawa succinic a me ka butyrolactone.
ʻO ka mea hoʻoheheʻe no nā polymers kiʻekiʻe, ʻoi aku ka polyvinyl chloride. Ma ke ʻano he mea hana no nā hopena Grignard a me ka metal hydride. I ka synthesis o ka butyrolactone, succinic acid, 1,4-butanediol diacetate. ʻO ka mea hoʻoheheʻe i nā ʻano hana histological. Hiki ke hoʻohana ʻia ma lalo o ke kānāwai Federal Food, Drug & Cosmetic no ka hana ʻana i nā mea no ka hoʻopili ʻana, ka lawe ʻana, a i ʻole ka mālama ʻana i nā meaʻai inā ʻaʻole iʻoi aku ka nui o ke koena ma mua o 1.5% o ke kiʻiʻoniʻoni: Fed. Regist. 27, 3919 (ʻApelila 25, 1962).
Hoʻohana nui ʻia ʻo Tetrahydrofuran (80%) e hana i ka polytetramethylene ether glycol, ka polymer kumu i hoʻohana nui ʻia i ka hana ʻana i nā olonā elastomeric (e like me spandex) a me nā elastomers polyurethane a me polyester (e like me ka ʻili artificial, nā huila skateboard). Hoʻohana ʻia ke koena (20%) i nā noi solvent (e like me nā sima paipu, nā mea hoʻopili, nā ʻīnika paʻi, a me ka lipine magnetic) a ma ke ʻano he solvent reaction i nā syntheses kemika a me nā lāʻau lapaʻau.
