Lwm lub npe rau tetrahydrofuran (THF) yog dab tsi?
Synonyms: THF, oxolane, 1,4-epoxybutane, oxacyclopentane, butylene oxide, cyclo tetramethylene oxide.
tetrahydrofuran (THF) yog dab tsi?
Tetrahydrofuran (THF), los yog oxolane, yog cov organic compound nrog cov mis (CH2) 4O. Lub compound yog cais raws li heterocyclic compound, tshwj xeeb yog cyclic ether. Nws yog xim tsis muaj xim, dej -miscible organic kua uas muaj viscosity tsawg. Nws yog tsuas yog siv los ua ib qho precursor rau polymers.

Chemical Properties:
THFfeem ntau yog cov tshuaj ruaj khov tab sis tuaj yeem tsim cov peroxides tawg thaum raug lub teeb lossis huab cua. Nws ua raws li Lewis lub hauv paus tsis muaj zog thiab tuaj yeem ua rau cov kua qaub. Nws cov qauv cyclic tso cai rau nws mus rau lub nplhaib - qhib cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm cov kua qaub los yog lub hauv paus catalysts, tsim derivatives xws li 1,4-butanediol.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
Qhov zoo
