Tetrahydrofuranyog ib qho tshuaj sib xyaw nrog cov mis molecular C4H8O. Nws yog cov kua uas tsis muaj xim, flammable nrog ib tug me ntsis qab zib tsw. Cov khoom no yog ib qho hnyav nyob rau hauv ntau yam kev lag luam, nrog rau cov kws kho mob, plastics, thiab polymer manufacturing. Thaum nws muaj qee qhov kev phom sij, tag nrho, Tetrahydrofuran tsis yog cov khoom txaus ntshai.
Ib qho kev pheej hmoo ntawmTetrahydrofuranyog nws flammability. Cov kua muaj qhov flashpoint ntawm -14 ° C thiab tuaj yeem ignite yooj yim yog tias nws los rau hauv kev sib cuag nrog lub txim taws, nplaim taws lossis cua sov. Txawm li cas los xij, qhov kev pheej hmoo no tuaj yeem tswj hwm los ntawm kev ua raws li kev khaws cia thiab tuav cov txheej txheem. Txhawm rau txo qhov kev pheej hmoo ntawm hluav taws thiab tawg, nws yog ib qho tseem ceeb uas yuav tsum khaws cov khoom kom deb ntawm qhov chaw ntawm qhov hluav taws kub thiab siv qhov cua kom zoo.
Lwm yam txaus ntshai ntawmTetrahydrofuranyog nws muaj peev xwm ua rau tawv nqaij khaus thiab chemical burns. Thaum cov kua tuaj rau ntawm daim tawv nqaij ncaj qha, nws tuaj yeem ua rau khaus, liab, thiab o. Qhov kev pheej hmoo no tuaj yeem txo qis los ntawm kev hnav khaub ncaws tsim nyog thiab cov cuab yeej tiv thaiv thaum tuav cov khoom. Cov hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv tuaj yeem tiv thaiv tawv nqaij.
TetrahydrofuranNws kuj yog cov kua tsis hloov pauv, uas txhais tau tias nws tuaj yeem vaporize tau yooj yim thiab nthuav tawm qhov ua rau muaj kev phom sij. Kev raug cov vapors ntev ntev tuaj yeem ua rau kiv taub hau, mob taub hau, thiab teeb meem ua pa. Txawm li cas los xij, qhov kev pheej hmoo no tuaj yeem zam tau los ntawm kev siv cov khoom siv nyob rau hauv qhov chaw muaj cua zoo thiab tsis txhob raug lub sijhawm ntev.
Txawm hais tias muaj peev xwm txaus ntshai no, Tetrahydrofuran yog cov khoom siv tau zoo. Nws yog feem ntau siv nyob rau hauv kev lag luam kws tshuaj ua ib qho hnyav rau cov khoom xyaw nquag. Nws kuj yog ib qho tseem ceeb hnyav nyob rau hauv zus tau tej cov polymers thiab plastics, qhov twg nws enables meej tswj nyob rau hauv cov txheej txheem thiab cov khoom kawg khoom.
Ntxiv mus, cov khoom no yog ib qho yooj yim mus lis thiab muaj ib tug tsawg toxicity. Nws tau pom tias muaj cov tshuaj toxicity tsawg hauv cov kev tshawb fawb ntawm cov tsiaj, ua rau nws muaj kev nyab xeeb rau kev siv hauv kev tswj kev tsim khoom. Cov khoom no kuj yog biodegradable, txhais tau tias nws lov ib txwm ua rau cov khoom tsis zoo nyob rau lub sijhawm.
Hauv kev xaus, thaum muaj kev pheej hmoo cuam tshuam nrogTetrahydrofuran, cov kev pheej hmoo no tuaj yeem tswj hwm los ntawm kev ua raws li kev tuav pov hwm kev nyab xeeb thiab khaws cia cov txheej txheem. Nrog nws txoj kev siv dav hauv ntau qhov kev lag luam thiab nws cov tshuaj toxicity tsawg, Tetrahydrofuran yog cov khoom muaj txiaj ntsig zoo thiab muaj txiaj ntsig uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom niaj hnub no. Tsuav nws siv kom raug, tsis muaj laj thawj xav tias nws yog cov khoom txaus ntshai.
