Kagwiritsidwe Ntchito
Tetrahydrofurfuryl alcohol (THFA) nthawi zambiri imaonedwa ngati chosungunulira "chobiriwira" m'mafakitale. THFA ndi chosungunulira chotsika mtengo, chomwe chimawonongeka chomwe chimagwiritsidwa ntchito makamaka ngati chosungunulira chothandizira ma epoxy resins ndipo ndi chosungunulira chabwino cha zinthu zambiri zochiritsa komanso zoyambitsa zomwe zimagwiritsidwa ntchito mu epoxy formulations. Chimagwiritsidwanso ntchito m'magwiritsidwe ntchito otsatirawa:
Tetrahydrofurfuryl alcohol imadutsa mu chemoselective hydrogenolysis yomwe imayambitsidwa ndi Rh/SiO2 yosinthidwa ndi ReOx species kuti ipange 1,5-pentanediol. Imadutsa mu lanthanum-mediated Michael-type addition reaction ndi maleate kuti ipange alkoxybutanedioic acid.
Mowa wa Tetrahydrofurfuryl unagwiritsidwa ntchito ngati chosungunulira chofananira ndi refractive-index kuti zitsimikizire kuti tinthu ta silica tolimba timayimitsidwa kuti tiyesedwe ndi rheological.
Mowa wa Tetrahydrofurfuryl ungagwiritsidwe ntchito ngati muyezo wowunikira kuchuluka kwa analyte m'makoswe ndi utsi wochokera ku mankhusu a mpunga pogwiritsa ntchito njira za chromatography.

Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Sungani pamalo ozizira komanso ouma, musawononge dzuwa
