2,4-Dinitrophenylhydrazine (CAS # 119-26-6)

2,4-Dinitrophenylhydrazine (CAS # 119-26-6)

zoo
Cov ntaub ntawv ntseeg tau
Liab crystalline hmoov. Lub melting point yog hais txog 200 ° C. Me ntsis soluble hauv dej, ethanol, soluble hauv acid. Kev tawg tuaj yeem tshwm sim thaum raug tshav kub, sib cuag nrog cov nplaim taws qhib, kub kub, kev sib txhuam, kev co, thiab kev cuam tshuam. Thaum kub hnyiab, nws emits toxic thiab irritating pa taws. Kev sib xyaw nrog oxidants tuaj yeem tsim cov khoom tawg.

Txoj kev
Cov ntaub ntawv ntseeg tau
Hydrazine sulfate raug tshem tawm hauv dej kub, poov tshuaj acetate tau ntxiv, txias tom qab boiling, ethanol ntxiv, cov khib nyiab tau lim tawm, thiab cov lim tau ntxuav nrog ethanol. 2,4-= nitrophenyl ethanol tau ntxiv rau cov tshuaj hydrazine saum toj no, thiab 2,4-= nitrophenylhydrazine tau txais los ntawm kev pom, ntxuav, ziab, thiab filtrate concentration.

siv
Cov ntaub ntawv ntseeg tau
Nws yog ib qho chromogenic reagent rau kev txiav txim siab ntawm aldehydes thiab ketones los ntawm nyias txheej chromatography. Nws yog siv los ua ultraviolet derivatization reagent rau aldehydes thiab ketones hauv organic synthesis thiab explosives manufacturing.

kev ruaj ntseg
Cov ntaub ntawv ntseeg tau
nas qhov ncauj LDso: 654mg / kg. Nws yog khaus rau qhov muag thiab tawv nqaij. Nws yog rhiab heev rau daim tawv nqaij. Cov khoom no yog nqus mus rau hauv lub cev, uas tuaj yeem ua rau methemoglobinemia thiab cyanosis. Khaws rau hauv qhov chaw txias, ventilated warehouse. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Lub tsev khaws khoom kub yuav tsum tsis pub tshaj 30 ° C. Tiv thaiv los ntawm tshav ntuj ncaj qha. Khaws lub thawv ntim kom nruj. Rau kev nyab xeeb vim li cas, nws feem ntau wetted thiab passivated tsis pub tsawg tshaj 25% dej thaum lub sij hawm cia thiab tsheb thauj mus los. Nws yuav tsum tau muab cais los ntawm oxidants thiab acids. Tsis txhob sib tov cia thiab kev thauj mus los.
