tshuaj muaj zog
Cov khoom no crystallizes tawm ntawm dej raws li cov hmoov dawb. Solubility hauv dej ntawm 25 ℃ yog 0.5g / L. Insoluble nyob rau hauv dej txias, cawv thiab cov organic solvents. Soluble nyob rau hauv sodium hydroxide, sodium carbonate thiab ammonia daws.
Txoj kev tsim khoom:
Cov tshuaj tiv thaiv ntawm ethylenediamine thiab chloroacetic acid. Ntxiv 100kg ntawm chloroacetic acid, 100kg ntawm dej khov thiab 135kg ntawm sodium hydroxide tov (30%) rau hauv cov tshuaj tiv thaiv kettle, thiab ces ntxiv 18kg ntawm 83% mus rau 84% ethylenediamine nyob rau hauv stirring. Incubate ntawm 15 ° C rau 1 teev. Ntxiv 30Chemicalbook% sodium hydroxide tov nyob rau hauv batch ntawm 10L txhua zaus. Tom qab txhua qhov sib ntxiv, ntxiv lwm batch tom qab cov tshuaj phenolphthalein kuaj tsis pom liab. Khaws rau hauv chav sov li 12 teev. Tshav kub rau 90 ° C thiab decolorize nrog activated carbon. Lim, ntxuav cov lim seem nrog dej, thiab thaum kawg kho tus nqi pH mus rau 3 nrog concentrated hydrochloric acid. Txias thiab crystallize, lim thiab ntxuav nrog dej kom txog thaum tsis muaj cov tshuaj chloride ion. Cov khoom qhuav.
Cov tshuaj tiv thaiv ethylenediamine nrog formaldehyde thiab sodium cyanide. Sib tov 60% ethylenediamine aqueous tov, 30% sodium cyanide aqueous tov thiab sodium hydroxide, thiab khaws cov sib tov ntawm 20 ° C rau 0.5h. Tom qab ntawd ntxiv formaldehyde aqueous tov dropwise. Tom qab cov tshuaj tiv thaiv, cov chemicalbook tau decompressed thiab cov dej evaporated. Tom qab ntawd rov ua cov haujlwm saum toj no, ntxiv cov formaldehyde ntau dhau rau lub sijhawm kawg kom tso cai rau sodium cyanide kom hnov qab tag nrho. Kho pH rau 1.2 nrog dilute acid. Ib tug dawb precipitate precipitated, lim, ntxuav nrog dej, thiab qhuav ntawm 110 ° C. Tau cov khoom.
Daim ntawv thov teb
Ethylenediaminetetraacetic acid (EDTA) yog ib qho tseem ceeb complexing neeg sawv cev. EDTA yog siv dav thiab tuaj yeem siv los ua cov tshuaj pleev xim rau hauv kev ua cov xim photosensitive cov ntaub ntawv, dyeing auxiliaries, fiber processing auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators, EDTA yog ib tug chelate sawv cev. Nws tuaj yeem tsim cov dej-soluble tshuaj lom neeg ruaj khov nrog cov hlau alkali, cov ntsiab lus tsis tshua muaj hauv ntiaj teb thiab cov hlau hloov pauv. Ntxiv nrog rau cov ntsev ntsev, tseem muaj cov ntsev ammonium thiab ntau cov ntsev xws li hlau, magnesium, calcium, tooj liab, manganese, zinc, cobalt, thiab txhuas. Txhua cov ntsev no muaj kev siv sib txawv. Tsis tas li ntawd, EDTA tseem tuaj yeem siv los tshem tawm cov hluav taws xob tsis zoo los ntawm tib neeg lub cev thiab ua lub luag haujlwm detoxifying. Nws kuj yog tus neeg sawv cev kho dej. EDTA kuj yog ib qho tseem ceeb qhia, tab sis nws yog siv los titrate hlau npib tsib xee, tooj liab, thiab lwm yam. Thaum siv, nws yuav tsum tau siv ua ke nrog ammonia los ua qhov taw qhia.
