Cov khoom no crystallizes tawm hauv dej ua hmoov dawb. Qhov solubility hauv dej ntawm 25 ℃ yog 0.5g / L. Insoluble hauv dej txias, cawv thiab cov organic solvents dav dav. Soluble hauv sodium hydroxide, sodium carbonate thiab ammonia kua.
Txoj kev tsim khoom:
Kev sib xyaw ntawm ethylenediamine thiab chloroacetic acid. Ntxiv 100kg ntawm chloroacetic acid, 100kg ntawm dej khov thiab 135kg ntawm sodium hydroxide kua (30%) rau hauv lub lauj kaub sib xyaw, thiab tom qab ntawd ntxiv 18kg ntawm 83% txog 84% ethylenediamine hauv qab kev sib xyaw. Incubate ntawm 15 ° C rau 1 teev. Ntxiv 30Chemicalbook% sodium hydroxide kua hauv cov pawg ntawm 10L txhua lub sijhawm. Tom qab txhua qhov ntxiv, ntxiv lwm pawg tom qab cov tshuaj ntsuam phenolphthalein tsis qhia liab. Khaws cia rau hauv chav sov rau 12 teev. Ua kom sov rau 90 ° C thiab decolorize nrog activated carbon. Lim, ntxuav cov lim dej seem nrog dej, thiab thaum kawg kho tus nqi pH rau 3 nrog concentrated hydrochloric acid. Txias thiab crystallize, lim thiab ntxuav nrog dej kom txog thaum tsis muaj chloride ion sib xyaw. Cov khoom qhuav.
Kev sib xyaw ntawm ethylenediamine nrog formaldehyde thiab sodium cyanide. Sib tov 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution thiab sodium hydroxide, thiab khaws cov khoom sib xyaw ntawm 20 ° C rau 0.5 teev. Tom qab ntawd ntxiv formaldehyde aqueous solution dropwise. Tom qab kev sib xyaw, cov tshuaj lom neeg tau decompressed thiab cov dej tau evaporated. Tom qab ntawd rov ua qhov kev ua haujlwm saum toj no, ntxiv cov formaldehyde ntau dhau rau lub sijhawm kawg kom tso cai rau sodium cyanide kom sib xyaw tag nrho. Kho pH rau 1.2 nrog dilute acid. Ib qho dawb precipitate precipitated, lim, ntxuav nrog dej, thiab ziab ntawm 110 ° C. Tau txais cov khoom.
Daim ntawv thov teb
Ethylenediaminetetraacetic acid (EDTA) yog ib qho tseem ceeb uas ua rau cov tshuaj sib xyaw ua ke. EDTA siv dav dav thiab siv tau ua cov tshuaj dawb hauv kev ua cov khoom siv xim, cov khoom siv zas xim, cov khoom siv ua fiber, cov khoom siv ntxiv rau cov khoom siv pleev xim, cov tshuaj tiv thaiv ntshav, cov tshuaj ntxuav tes, cov tshuaj stabilizer, cov tshuaj pib polymerization roj hmab. EDTA yog chelate uas yog cov khoom sib xyaw ua ke. Nws tuaj yeem tsim cov tshuaj sib xyaw ua ke uas yaj tau hauv dej nrog cov hlau alkali, cov hlau tsis tshua muaj thiab cov hlau hloov pauv. Ntxiv rau cov ntsev sodium, kuj tseem muaj cov ntsev ammonium thiab ntau yam ntsev xws li hlau, magnesium, calcium, tooj liab, manganese, zinc, cobalt, thiab txhuas. Txhua cov ntsev no muaj ntau yam kev siv. Tsis tas li ntawd, EDTA kuj tseem siv tau los tshem tawm cov hlau radioactive uas ua rau lub cev tsis zoo thiab ua lub luag haujlwm tshem tawm cov tshuaj lom. Nws kuj yog ib qho tshuaj kho dej. EDTA kuj tseem yog ib qho cim qhia tseem ceeb, tab sis nws siv los titrate hlau nickel, tooj liab, thiab lwm yam. Thaum siv, nws yuav tsum siv ua ke nrog ammonia los ua lub cim qhia.
