Ukusetshenziswa
I-Tetrahydrofurfuryl alcohol (THFA) ngokuvamile ibhekwa njengesinyibilikisi "esiluhlaza" ezisetshenziswa ezimbonini. I-THFA iyisinyibilikisi esingabizi kakhulu, esibolayo esisetshenziswa kakhulu njengesinyibilikisi esisebenzayo sama-resin e-epoxy futhi iyisinyibilikisi esihle sama-catalyst amaningi okwelapha kanye nama-catalyst asetshenziswa ekwakhiweni kwe-epoxy. Isetshenziswa futhi kulezi zicelo ezilandelayo:
I-Tetrahydrofurfuryl alcohol idlula ku-hydrogenolysis ekhethayo eqhutshwa yi-Rh/SiO2 eguqulwe ngezinhlobo ze-ReOx ukuze ikhiqize i-1,5-pentanediol. Idlula ku-reaction ye-Michael-type addition eqhutshwa yi-lanthanum ne-maleate ukuze yakhe i-alkoxybutanedioic acid.
I-Tetrahydrofurfuryl alcohol yasetshenziswa njengesithako esifanisa inkomba yokubuyisa ukuze kuqinisekiswe ukumiswa kwe-hard sphere yezinhlayiya ze-silica ukuze kulinganiswe i-rheological.
I-Tetrahydrofurfuryl alcohol ingasetshenziswa njengendinganiso yokubhekisela yokuhlaziya yokulinganisa i-analyte kumagundane kanye nokunambitheka kwentuthu okuvela eqoqweni lelayisi kusetshenziswa amasu e-chromatography.
Ukupakisha:
220KG/Isigubhu
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Gcina endaweni epholile neyomile, ungavezi ilanga
