Kev Siv
Tetrahydrofurfuryl cawv (THFA) feem ntau suav hais tias yog cov kuab tshuaj "ntsuab" hauv kev siv hauv kev lag luam. THFA yog cov kuab tshuaj pheej yig, biodegradable feem ntau siv ua cov tshuaj reactive rau epoxy resins thiab yog cov kuab tshuaj zoo rau ntau yam tshuaj kho thiab cov catalysts siv hauv epoxy formulations. Nws kuj tseem siv rau hauv cov ntawv thov hauv qab no:
Cawv Tetrahydrofurfuryl raug chemoselective hydrogenolysis catalyzed los ntawm Rh/SiO2 hloov kho nrog ReOx hom kom tau 1,5-pentanediol. Nws raug lanthanum-mediated Michael-type addition reaction nrog maleate los ua alkoxybutanedioic acid.
Tetrahydrofurfuryl cawv tau siv los ua cov kuab tshuaj sib phim refractive-index kom ntseeg tau tias cov khoom siv silica raug tshem tawm rau kev ntsuas rheological.
Tetrahydrofurfuryl cawv yuav siv tau ua tus qauv siv los ntsuas qhov ntsuas ntawm cov analyte hauv nas thiab cov pa luam yeeb los ntawm cov txhuv nplej siv cov txheej txheem chromatography.
