Taw qhia
4-Cyanophenylhydrazine hydrochloride yog ib qho organic compound nrog cov tshuaj formula C6H6N4 · HCl. Cov hauv qab no yog cov lus qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv:
Xwm:
4-Cyanophenylhydrazine hydrochloride yog cov dawb crystalline khoom, soluble hauv dej thiab qee cov kuab tshuaj organic. Nws yog flammable thiab tej zaum yuav tsim cov pa phem.
Siv:
4-Cyanophenylhydrazine hydrochloride yog ib qho kev siv tshuaj nruab nrab. Nws tuaj yeem siv los ua cov khoom siv raw rau cov organic synthesis cov tshuaj tiv thaiv, piv txwv li, rau cov synthesis ntawm dyes, fluorescent dyes los yog organometallic complexes, thiab lwm yam. Tsis tas li ntawd, nws kuj yog siv nyob rau hauv cov kws tshuaj raws li ib tug hluavtaws intermediate rau tej yam tshuaj.
Txoj kev:
4-Cyanophenylhydrazine hydrochloride feem ntau yog npaj los ntawm reacting phenylhydrazine hydrochloride nrog sodium cyanide. Phenylhydrazine hydrochloride thiab sodium cyanide yog thawj zaug yaj hauv cov kuab tshuaj sib thooj, tom qab ntawd ob txoj kev daws teeb meem sib xyaw thiab cov tshuaj tiv thaiv yog nplawm ntawm qhov kub thiab txias rau lub sijhawm. Thaum kawg, cov khoom nyoos yog tau los ntawm kev pom, thiab ua kom huv los ntawm kev ntxuav thiab recrystallization kom tau txais cov khoom ntshiab.
Cov ntaub ntawv kev nyab xeeb:
4-Cyanophenylhydrazine hydrochloride yog irritating thiab corrosive thiab tej zaum yuav ua rau puas tsuaj rau daim tawv nqaij, qhov muag thiab ua pa ib ntsuj av. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, tsom iav thiab qhov ncauj qhov ntswg yuav tsum hnav thaum siv. Tsis txhob muaj plua plav thaum lub sijhawm ua haujlwm thiab tswj kom muaj qhov cua zoo hauv chav kuaj. Yog tias koj tau ntsib nrog nws, koj yuav tsum tam sim ntawd yaug nrog dej kom ntau thiab nrhiav kev kho mob. Tsis tas li ntawd, nws yuav tsum tau khaws cia kom deb ntawm hluav taws thiab oxidizing tus neeg sawv cev thiab khaws cia rau hauv qhov chaw qhuav, txias.
