Khoom: 4-fluoro-2-iodotoluene yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw tshwj xeeb ntawm chav sov. Nws muaj qhov ntom ntawm 1.839g / cm³, melting point ntawm -1 ° C, boiling point ntawm 194 ° C, thiab yog insoluble nyob rau hauv dej tab sis soluble nyob rau hauv organic solvents.
Kev Siv: 4-Fluoro-2-iodotoluene feem ntau yog siv rau hauv cov organic synthesis cov tshuaj tiv thaiv thiab tuaj yeem siv los ua ib qho nruab nrab rau cov tshuaj tsw qab. Nws tuaj yeem siv los ua cov khoom sib txuas xws li tshuaj, tshuaj tua kab, pigments thiab dyes.
Txoj kev npaj: 4-fluoro-2-iodotoluene tuaj yeem npaj tau los ntawm reacting iodotoluene nrog hydrogen fluoride. Cov kev mob tshwm sim feem ntau yog me me, thiab yuav tsum tau ceev faj txog kev nyab xeeb.
Cov ntaub ntawv kev nyab xeeb: 4-fluoro-2-iodotoluene yog cov organic compound, thiab koj yuav tsum tau xyuam xim rau kev nyab xeeb thaum siv. Nws feem ntau cuam tshuam rau tib neeg lub cev los ntawm kev nqus pa thiab kev sib cuag ntawm daim tawv nqaij. Kev raug mob mus ntev yuav ua rau khaus lossis puas rau lub ntsws, tawv nqaij, thiab qhov muag. Hnav cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes, tsom iav thiab lub qhov ncauj qhov ntswg, tuav lub qhov cua kom zoo, thiab tsis txhob sib cuag nrog cov khoom siv hluav taws xob. Thaum khaws cia thiab tuav, khaws cia kom deb ntawm cov khoom siv hluav taws xob thiab oxidants, thiab pov tseg cov pov tseg kom zoo. Ua raws li cov txheej txheem kev nyab xeeb thiab cov kev cai tseem ceeb heev los tiv thaiv kev nyab xeeb ntawm tib neeg lub cev thiab ib puag ncig. Nyeem thiab soj ntsuam Daim Ntawv Qhia Kev Nyab Xeeb Khoom (MSDS) ua ntej siv.
