Product name:3-Nitrophenol
CAS: 554-84-7
Molecular Formula: C6H5NO3
Molecular Weight: 139.11
Product description:Colorless to light yellow crystal.Slightly soluble in water, soluble in ethanol, ethyl ether, acetone, dilute acid and alkali solution, etc.By nitroaniline by diazotization; Hydrolysis. Between the nitrobenzene in dilute sulphuric acid, mix slowly cooled to below 0 ℃. Aqueous solution under stirring slowly adding sodium nitrite, and keep the temperature is below 15 ℃, after completion of diazotization reaction liquid should be dark brown transparent liquid. The diazonium salt again at 125 ℃ of hot mix slowly dilute sulphuric acid, adding insulation after 1 to 2 h. Put cold, crystallization will filter out, washed with water to pH = 3-4, drain, vacuum distillation for a quick finished products.Used as the indicator, fungicides and used in organic synthesis.
