Ibisobanuro:
Alcool ya Tetrahydrofurfuryl ni alcool y'ibanze ari yo methanol aho imwe muri hydrogen zo mu itsinda rya methyl yasimbuwe n'itsinda rya tetrahydrofuran-2-yl. Ifite uruhare nk'umusemburo wa protic. Ni alcool y'ibanze ikaba n'igice cya oxolane.

Imikoreshereze
Alcool ya Tetrahydrofurfuryl (THFA) muri rusange ifatwa nk'umusemburo "w'icyatsi" mu nganda. THFA ni umusemburo uhendutse kandi ushobora kubora ukoreshwa cyane cyane nk'umusemburo uvura resins za epoxy kandi ni umusemburo mwiza ku bintu byinshi bivura n'ibikoreshwa mu gukora epoxy. Ikoreshwa kandi muri ibi bikurikira:
Inzoga ya Tetrahydrofurfuryl inyura muri hydrogenolysis ikoresha uburyo bwa chemoselective ikoresheje Rh/SiO2 yahinduwe na ReOx species kugira ngo itange 1,5-pentanediol. Inyura muri Michael-type addition reaction ikoresheje lanthanum hamwe na maleate kugira ngo ikore aside alkoxybutanedioic.
Alkoholi ya Tetrahydrofurfuryl yakoreshejwe nk'umusemburo uhuza refractive-index kugira ngo habeho ko uduce twa silica duhagarara mu bipimo bya rheological.
Inzoga ya Tetrahydrofurfuryl ishobora gukoreshwa nk'igipimo ngenderwaho cyo gusesengura mu gupima uburyohe bw'imbeba n'ibiryohe by'umwotsi biva mu gishishwa cy'umuceri hakoreshejwe uburyo bwa chromatography.
