| titleOfInvention | A kind of vanadium catalyst for nitrobenzene sulfonation and preparation method thereof |
| abstract | The invention discloses a kind of vanadium catalyst for nitrobenzene sulfonation, by Vn 2 on 5 , Kn 2 sOn 4 , aluminium salt, calcium salt and silicon carrier composition, wherein, Vn 2 on 5 mass content be 20-30%, Kn 2 sOn 4 mass content be 5.5-10%, aluminium salt is with Aln 2 on 3 the mass content of metering is 1-2.5%, the calcium salt mass content of measuring with CaO is 5.5-10%, surplus is for silicon carrier.The vanadium catalyst of the nitrobenzene sulfonation of gained of the present invention, has that the burn into of resistance to oleum intensity is high, activity stabilized, active principle turnover rate is low, object products collection efficiency advantages of higher; Can apply mechanically more than 5 times, after applying mechanically 5 times, active component vanadic anhydride turnover rate is less than 10%, has saved production cost, decreases useless acid-treated difficulty, reduces the pollution to environment. |
