Kopo
Iodide ea sodium e sebelisoa haholo bakeng sa phapanyetsano ea halide (karabelo ea Finkelstein), mohlala, phetohong ea alkyl chloride, allyl chloride le arylmethyl chloride ho li-iodide tsa tsona, e leng li-precursor tsa lihlahisoa tsa meriana le lik'hemik'hale tse ntle. Li sebelisoa ho ntlafatsa katleho ea ho thehoa ha li-adducts tsa Wittig ho tsoa ho li-chloride le li-bromide tse sa arabeleng haholo. Litokisetso tse loketseng li sebelisoa e le tlatsetso ea limatlafatsi. Iodide ea sodium e sebelisoa e le selelekela sa moemeli oa taolo ho polymerization ea ab initio emulsion. Iodide ea sodium e sebelisoa ho fumaneng oksijene e qhibilihisitsoeng mokhoeng o fetotsoeng oa Winkler, ho kopanngoa ha dae ea fluorescent coppersensor-1 (CS1) bakeng sa ho etsa litšoantšo tsa matamo a koporo a labile lisampoleng tsa baeloji, le karohano ea li-ester, lactones, carbamates le ethers hammoho le chlorotrimethylsilane.
