Tshuaj lom ua kua Tetrahydrofrofururan purity 99.9% CAS {2}}?
TetrahyDrofuran (CAS {109-99-9) yog cov kua txob, nrog lub cev muaj ntxhiab tsw qab, thiab cov tshuaj molecular hnyav ntawm 72.11 g / mol.
TetrahyDrofuran muaj lub qhov cub npau npau ntawm 66 degree, lub ntsej muag melting ntawm {}}. 8}}} degree (kaw khob). Nws yooj yim accumulates nyob rau hauv thaj chaw qis-las los ua cov khoom sib xyaw tawg. TetrahyDrofuran yog yooj yim oxidized rau hauv huab cua los ua peroxides, thiab stabilizers (xws li BHT) yuav tsum tau ntxiv rau lub sijhawm ntev cia.

Kev siv
Raws li kev daws teeb meem rau txheej, inks, thiab cov nplaum, TetrahyDrofuran tuaj yeem txhim kho kev vam meej kev ua haujlwm thiab nplaum ntawm cov txheej txheem. Nws cov solubility siab ua rau nws tseem ceeb ntawm photoresist cov kuab tshuaj, uas tau siv nyob rau hauv cov txheej txheem ua ntej patterning hauv semiconductor kev tsim khoom. Ntxiv rau, TetrahyDrofuran tseem tuaj yeem siv los tsim cov polyurethane elastomers, spandex fibers, thiab lwm yam.
Chaw Ua Haujlwm Tshiab
Raws li ib qho ntxiv rau cov roj teeb lithium-ion tau txhim kho qhov ntsuas hluav taws xob tsawg thiab lub voj voog lub neej ntawm lub roj teeb. Nws cov diteectric tas li yuav pab kom nce kev sib cais ntawm cov ntsev lithium thiab txhim kho ion conductivity.
Cov Ntaub Ntawv Kev Nyab Xeeb
TetrahyDroFofuran vapor yog khaus rau lub qhov muag thiab kev ua pa rau kev ua pa. Kev nqus tau cov kev ua kom siab tuaj yeem ua rau mob taub hau, xeev siab, thiab nruab nrab ntawm lub paj hlwb nyuaj siab. Lub sijhawm ntev yuav ua rau mob siab thiab raum puas tsuaj. Irc tau cais nws ua chav kawm 2B carcinogen.
Nws yog cov dej-doluble (ua kom tiav nrog dej), nyuaj rau biodegrade, thiab yooj yim rau cov paug tsis yooj yim. Nws cov mob toxicity rau dej yug tsiaj (LC50) yog 120-240 mg / l, uas yuav cuam tshuam rau kev sib npaug ntawm cov dej lub cev.
