Daim ntawv thov
TetraYDrofuran tuaj yeem tawg thaum sib xyaw nrog huab cua; Nws tuaj yeem tsim cov peroxide tawg rau saum huab cua, uas yog cov nplaim taws thaum qhib cov nplaim taws, kub thiab oxidant; Kev hlawv cov pa luam yeeb. Yog heterocyclic organic compound. Nws yog cov neeg muaj kev nyab xeeb thiab yog cov khoom lag luam hydrogenation tag nrho ntawm cov neeg muaj ntxhiab tsw furan. Nws yog siv los ua cov polarately loj polar agor farvent hauv tshuaj lom neeg cov kev tshua thiab muab cov tshuaj tiv thaiv. TetrahyDrofuran yog qee qhov tsis raug nrog dej ntawm chav tsev kub, thiab qee cov khoom lag luam tsis txaus ntseeg siv cov txiaj ntsig loj los ntawm cov dej ntxiv rau Tetranthlofofofuran reagent. TetrahyDrofuran tau yooj yim rau hauv peroxide thaum lub sij hawm cia. Yog li ntawd, coj mus muag Tetranthadrofuran feem ntau tiv thaiv los ntawm oxidation nrog BHT, 2,6 - TERT - Butyl - 4 - Methylfphenol. TetrahyDrofuran tuaj yeem khaws cia rau hauv lub vial vial nrog sodium hydroxide hauv qhov chaw tsaus.
TetrahyDrofuran muaj cov yam ntxwv ntawm cov tshuaj lom tsawg, tsis tshua muaj boiling taw tes thiab zoo fluidity. Nws yog ib qho khoom tseem ceeb rau cov khoom siv hauv cov organic thiab cov kuab tshuaj zoo heev. Nws muaj ntau yam kev siv. TetrahyDrofuran muaj solubility zoo rau ntau cov organic. Txhua cov organic sib xyaw tsis yog propylene thiab fluororesins, tshwj xeeb siv raws li cov tshuaj uas tsim nyog, thiab cov tshuaj tiv thaiv zoo, uas yog hu ua "Universal hnyav".
