Sodium diethyldithiocarbamate, chemical formula (C2H5) 2ncssna, dawb mus rau xim tsis muaj xim flake siv lead ua. Hygroscopic. Nws yog yooj yim soluble nyob rau hauv dej, ethanol, methanol thiab acetone, tab sis insoluble nyob rau hauv ether thiab benzene. Nws tuaj yeem siv ua tooj liab reagent hauv kev sim.
Muaj peb yam tshuaj lom neeg:
1, Oxidized rau disulfide
Lub oxidation ntawm sodium diethyldithiocarbamate tsim disulfide, uas yog, colchicine disulfide:
2 NaS2CNEt2 + I2 → Et2NC ( S ) S-SC ( S ) NEt2 + 2NaI
Qhov no disulfide tau muag raws li cov tshuaj tiv thaiv dej cawv raws li cov npe ntawm Antabuse thiab Disulfiram. Cov tshuaj chlorination ntawm cov disulfide tuaj yeem muab cov aminothiocarbonyl chloride.
2. Ua ib tug ligand
Diethyldithiocarbamate tuaj yeem chelate nrog ntau' mos' hlau ions los ntawm ob lub sulfur atoms. Lwm txoj kev sib txuas ua ke kuj tseem paub, xws li siv ib qho ntawm ob qho sulfur atoms ua ib tus hniav ligand lossis bridging ligand. Vim tias nws tuaj yeem tsim cov phiaj xwm square nrog tooj liab ions thiab grey-ntsuab complex tuaj yeem muab rho tawm los ntawm carbon tetrachloride, qee zaum hu ua / 3, tooj liab reagent.
Spin trapping ntawm nitric oxide dawb radicals
Diethyldithiocarbamate-hlau complex yog ib qho ntawm ob peb txoj hauv kev uas tuaj yeem muab kev tshawb fawb txog kev tsim cov nitric oxide (NO) dawb radicals hauv cov khoom siv roj ntsha. Txawm hais tias cov ntaub so ntswg ib nrab-lub neej ntawm NO yog luv heev uas nws tsis tuaj yeem kuaj pom, TSIS tau yooj yim los ua ke nrog cov complex no. Cov tsim mononitroso-hlau complex ( E : MNIC ) ruaj khov thiab tuaj yeem kuaj pom hauv cov spectrum los ntawm electron spin resonance (EPR).
Sodium diethyldithiocarbamate tuaj yeem tau txais los ntawm kev sib xyaw ntawm carbon disulfide thiab diethylamine thiab neutralization nrog sodium hydroxide:
CS2 + HN ( C2H5 ) 2 + NaOH → NaS2CN ( C2H5 ) 2 + H2O
Lwm cov dithiocarbamates kuj tuaj yeem tau los ntawm kev sib xyaw cov amine theem nrab thiab carbon disulfide tib yam. Lawv feem ntau yog siv los ua chelating ligands ntawm kev hloov hlau ions thiab precursors ntawm cov khoom hauv herbicides thiab sulfides.
