Isticmaalka
Khamriga Tetrahydrofurfuryl (THFA) guud ahaan waxaa loo arkaa dareere "cagaaran" codsiyada warshadaha. THFA waa dareere qiimo jaban, oo bayooloji ahaan u burburi kara oo inta badan loo isticmaalo sidii dareere falgal ah oo loogu talagalay resins-ka epoxy waana dareere wanaagsan oo loogu talagalay qaar badan oo ka mid ah daawooyinka iyo kaaliyeyaasha loo isticmaalo qaacidooyinka epoxy. Waxaa sidoo kale loo isticmaalaa codsiyada soo socda:
Khamriga Tetrahydrofurfuryl wuxuu maraa hydrogenolysis kiimoselective ah oo lagu kiciyay Rh/SiO2 oo lagu beddelay noocyada ReOx si uu u soo saaro 1,5-pentanediol. Waxay martaa falgal ku darid nooca Michael oo la socota lanthanum oo leh maleate si ay u samayso aashitada alkoxybutanedioic.
Khamriga Tetrahydrofurfuryl waxaa loo isticmaalay sidii dareere isku-dhafan oo refractive-index ah si loo hubiyo joojinta adag ee walxaha silica si loo cabbiro rheological.
Khamriga Tetrahydrofurfuryl waxaa loo isticmaali karaa halbeeg tixraac falanqayn ah oo loogu talagalay cabbirka falanqeeyaha ee jiirka iyo dhadhanka qiiqa ee ka imanaya qolofka bariiska iyadoo la adeegsanayo farsamooyinka koromagrafiga.
