He huahana weliweli anei ʻo Tetrahydrofuran?

Tetrahydrofuranhe hui kemika me ke kumu molekula C4H8O. He wai waihoʻoluʻu ʻole, ʻaʻohe ʻala me ka ʻala ʻoluʻolu. He mea hoʻoheheʻe maʻamau kēia huahana i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, plastics, a me ka hana polymer. ʻOiai loaʻa iā ia kekahi mau pōʻino, ma ka laulā, ʻaʻole ʻo Tetrahydrofuran kahi huahana pōʻino.

 

Kekahi pilikia oTetrahydrofuranʻo ia kona hikiwawe. Loaʻa i ka wai ke kukui uila o -14°C a hiki ke hoʻā maʻalahi ke hoʻopili ʻia me kahi huna ahi, lapalapa a me ka wela. Eia nō naʻe, hiki ke mālama ʻia kēia pilikia ma o ka hahai ʻana i nā kaʻina mālama mālama a me ka mālama ʻana. No ka ho'ēmiʻana i ka hopena o ke ahi a me ka pahūʻana, he mea nui e mālama i ka huahana mai nā kumu o ke ahi a hoʻohana i ka ea kūpono.

 

ʻO kekahi pōʻino paha oTetrahydrofuranʻo ia ka hiki ke hoʻoulu i ka ʻili a me ke kuni kemika. Ke hele pololei mai ka wai me ka ʻili, hiki iā ia ke hoʻonāukiuki, ʻulaʻula, a me ka pehu. Hiki ke hōʻemi ʻia kēia pilikia ma ke komo ʻana i nā lole kūpono a me nā mea pale i ka wā e lawelawe ana i ka huahana. Hiki i nā mīkina lima, nā maka aniani, a me nā lole pale ke pale i ka ʻike ʻana i ka ʻili.

 

Tetrahydrofuranhe wai hoʻoheheʻe ʻia, ʻo ia hoʻi, hiki iā ia ke lele maʻalahi a hōʻike i kahi pōʻino inhalation. ʻO ka loaʻa ʻana i ka mahu e hiki ke alakaʻi i ka noʻonoʻo, ke poʻo, a me nā pilikia hanu. Eia nō naʻe, hiki ke pale ʻia kēia pilikia ma ka hoʻohana ʻana i ka huahana ma kahi wahi i hoʻoluʻu maikaʻi ʻia a pale aku i ka ʻike lōʻihi.

 

ʻOiai ʻo kēia mau pōʻino, ʻo Tetrahydrofuran kahi huahana pono loa. Hoʻohana maʻamau ia i ka ʻoihana lāʻau lapaʻau ma ke ʻano he solvent no nā mea hana. He mea hoʻoheheʻe koʻikoʻi ia i ka hana ʻana i nā polymers a me nā plastics, kahi e hiki ai ke hoʻokele pololei i nā kūlana hana a me nā waiwai huahana hope loa.

 

Eia kekahi, maʻalahi kēia huahana a he haʻahaʻa haʻahaʻa. Ua hōʻike ʻia he haʻahaʻa haʻahaʻa o ka ʻawaʻawa i nā haʻawina e pili ana i nā holoholona, ​​​​hiki ke palekana no ka hoʻohana ʻana i nā kaʻina hana hoʻomalu. He biodegradable nō hoʻi kēia huahana, ʻo ia hoʻi, e wāwahi maoli ia i mau mea ʻino ʻole i ka manawa.

 

I ka hopena, ʻoiai aia nā pilikia pili meTetrahydrofuran, hiki ke mālama ʻia kēia mau pilikia ma o ka hahai ʻana i nā kaʻina hana palekana a mālama. Me kona hoʻohana nui ʻana i nā ʻoihana like ʻole a me kona ʻano haʻahaʻa haʻahaʻa, ʻo Tetrahydrofuran kahi huahana palekana a waiwai nui e hana nui i nā kaʻina hana hana hou. I ka wā e hoʻohana pono ʻia ai, ʻaʻohe kumu e noʻonoʻo ai he huahana pōʻino.
