Chemical Properties:ntshav liab hmoov. Nws yog soluble hauv o-chlorophenol, me ntsis soluble hauv chloroform, pyridine, toluene, thiab insoluble hauv acetone thiab ethanol. Nws yog xim liab thiab txiv kab ntxwv nyob rau hauv concentrated sulfuric acid, xim av (nrog ntsuab fluorescence) nyob rau hauv alkaline sodium hydrosulfite tov, thiab txiv kab ntxwv nyob rau hauv acid kua. Daim ntawv thov: Redox 2R yog tsim rau luam ntawv thiab dyeing ntawm paj rwb ntaub, thiab kuj siv raws li organic pigment.
Txoj kev tsim khoom:
Txoj Kev 1: Lub vat liab GG (Vat Red 14) tau kho nrog ethanol thiab potassium hydroxide, lim, evaporated thiab acidified.
Txoj Kev 2: Cov hydrochloride, sulphonate lossis hydrobromic acid ntsev ntawm caws pliav GG raug txo los ntawm fractional crystallization los ntawm cov kuab tshuaj organic. Los yog ntsev tau los ntawm kev kho nrog cov organic acid muaj zog. Txoj Kev 3: Liab GG tuaj yeem txo tau los ntawm kev kho nrog txhuas chloride lossis zinc chloride nrog lossis tsis muaj kuab lom. Cov khoom yog ces crystallized nyob rau hauv theem.
