Hoʻohana
ʻO ka waiʻona Tetrahydrofurfuryl (THFA) i manaʻo nui ʻia he mea hoʻoheheʻe "ʻōmaʻomaʻo" i nā noi ʻoihana. ʻO THFA kahi mea hoʻoheheʻe biodegradable haʻahaʻa ke kumukūʻai i hoʻohana nui ʻia ma ke ʻano he mea hoʻoheheʻe reactive no nā resins epoxy a he mea hoʻoheheʻe maikaʻi no nā mea hoʻōla a me nā mea hoʻoulu i hoʻohana ʻia i nā ʻano epoxy. Hoʻohana ʻia hoʻi ia i nā noi aʻe:
Hoʻopilikia ʻia ka waiʻona Tetrahydrofurfuryl i ka hydrogenolysis chemoselective i hoʻoulu ʻia e Rh/SiO2 i hoʻololi ʻia me nā ʻano ReOx e hua mai i ka 1,5-pentanediol. Hoʻopilikia ia i ka hopena hoʻohui ʻano Michael-type i hoʻopili ʻia e lanthanum me ka maleate e hana i ka waikawa alkoxybutanedioic.
Ua hoʻohana ʻia ka waiʻona Tetrahydrofurfuryl ma ke ʻano he mea hoʻoheheʻe refractive-index e hōʻoia i ka hoʻokuʻu ʻia ʻana o ka sphere paʻakikī o nā ʻāpana silica no nā ana rheological.
Hiki ke hoʻohana ʻia ka waiʻona Tetrahydrofurfuryl ma ke ʻano he kūlana kuhikuhi loiloi no ka helu ʻana o ka analyte i loko o nā ʻiole a me ka ʻono uahi mai ka ʻili laiki me ka hoʻohana ʻana i nā ʻano hana chromatography.
