Keikuakimao, ustboediated thf,ʻo ia kahi hui heterocyclic. No ka papa o ka eter

ʻO Tetrahydrofuran kekahi o nā makuahine ikaika loa. Hoʻohanaʻia ia ma keʻano he polar Polar i hoʻopaʻaʻia i nā hana kūlohelohe a me ka hoʻoiliʻana. He waihoʻoluʻu kalaʻoleʻoleʻia ma ka mahana o ka lumi a heʻono e like me ka eter. E hoʻomū i ka wai, ethanol, ka acetone, ka acetone, ka chesent aʻoi aku i ka "Universant". Ma ka lumi lumi a me ka wai hiki ke hoʻokaʻawale i kaʻoihana,ʻo kekahiʻoihana hanaʻole e hoʻohana i kēia manawa e hoʻohana ai i kēia manawa i keʻano o ka hanaʻana i ka wai. Ma muli o keʻano o ka thf e hana i nā peroxides e mālama ai,ʻo ka bht antiexidant bht ka mea maʻamau i hoʻohuiʻia i nā huahanaʻoihanaʻoihana. ʻO kaʻike moistture ≦ 0.2%.

Hiki iā Tetraydrofuran ke lilo i polyconderation (e ke kiʻi houʻana i keʻano repollymerization) i loko o nā polytemememethenyyyyyyyyyyyyyyylor. PTMEG a me Tluene Diisocynate (Tdi) hana i ka paleʻana i ka paleʻana i ka paleʻana, a me nā maka kūpono o ka'ōpū BLOT BLOCKLETER PYESTER PYESTER FIENTICECLES Ua hoʻomākaukauʻia me Dimethyl Terephtharat a me 1, 4-Boumantiol. Ptmeg me ka paona molecular molecular o 2000 a me p-atheyyne bis (4-phenyl) ʻO ka hoʻohana nuiʻana o ka thf no ka hanaʻana o ka ptmeg. Wahi a nā helu helu paʻakikī, e pili ana i 80% o ka 80% o ka global thf i hoʻohanaʻia no ka hanaʻana o ka ptmeg, aʻo ka ptmeg e hoʻohana nuiʻia no ka hanaʻana o ka ptmeg.

2. Hoʻopau me ka hana maikaʻi loa:

ʻO Tetrahydrofuran kahi maʻamau maʻamau i hoʻohana pinepineʻia, kūpono loa no ka weheʻana i ka fofide a me ka filchuylidene colloride E hoʻomoʻi a me nā kukui. Solivent no ka hoʻopiliʻana i nā coating, pvc mika, ka hoʻomaʻemaʻe pvc

Chromatographic chrisvent (gel permeation chromatography) Ke hoʻonui nei ka'āina, aʻo ka noi no ka Tetrabydrofuran e hōʻike pū ana ka ulu wikiwiki wikiwiki.

ʻAkahi:ʻO Tetrahydrofuran no ka papa o ka papa hana 3.1ʻO ka wai haʻahaʻa haʻahaʻa, hiki i keʻano o ka lewa. ʻO kānaʻano kaulana loa he mea palekana palekana. ʻO ka hopohopo nui loa me nā thfs ka lōʻihi o ka hanaʻana o nā peroxidice maikaʻi loa i hōʻikeʻia i ka lewa. E hōʻemi i kēia pilikia I ka manawa like,ʻaʻole pono e maloʻo ka thf no ka mea e hoʻopiliʻia nā peroxides no ka hanaʻana o nā peoxides i ke koena o ke koena.

ʻO ka hoʻomaʻamaʻa hana:ʻO ka hana paʻa, piha piha. Pono e hoʻomaʻamaʻaʻia nā mea hana a paʻa i nā kaʻina hana hana. Hāʻawiʻia ia i nā mea hana e kau ai i kahi kīkī spet mask mask (hapalua o nā aniani pale E mālama i ke ahi, kumu wela,ʻaʻohe o ka ulaula i ka wahi hana. E hoʻohana i nā'ōnaehana hoʻonohonoho explosion-profillition a me nā lako hana. Kāohi i ka Steam mai ka pakeleʻana i ka ea hana. Hōʻalo i ka hoʻopiliʻana me nā meaʻo Axidants, edids a me nā waihona. Pono ke kauʻia ka huina o ka kahe i ka wā e hoʻopiha ai, a aia i kahi hana e pono ai ke pale i ka hōʻiliʻili kaulikeʻana. Ke hana nei ka mālamaʻana, e laweʻia ke kukui a me ka weheʻana e pale aku ai e pale i ka pōʻino i ka hoʻopiliʻana a me nā mea paʻa.
