| titleOfInvention | Process for the preparation of 2-hydroxy-6-nitro-toluene |
| abstract | The present invention relates to 2-hydroxy-6-nitro-toluene of formula IVnfor the production of toluene nitration, dinitro toluenesnisomeric mixture, the 2,6-dinitro-nToluene reduction followed by 2-amino-6-nitro-toluenenby diazotizing and brewing, such that andinitro toluene is obtained by nitration of toluene.n■ a mixture with sodium hydroxide in the presence of methanolnreacted for a prolonged period of time, the excellent formula (H)nSeparates 2,6-dinitro toluene and then with sodium sulfidenreduced in the presence of ammonium chloride and an2-Amino-nitro-toluene of formula III is 34-56%nsulfuric acid diazotals and then diazonium saltnAt 70-90 ° C and givennin the case of a solution of the diazonium salt to an additional amountnsulfuric acid. |
