| titleOfInvention | The method of obtaining the sodium salt of the 1-nitroso-2-naphthol iron complex |
| abstract | 1. The method of obtaining the sodium salt of the iron complex of 1-nitroso-2-naphtholnby nitrosation of 2-naphthol, sulphation of the produced 1-nitroso-2-naphthol, metallizationnferrous sulfate and precipitation of the pigment with sodium carbonate solution,ncharacterized in that the nitrosation reaction is carried out in the presence of the disodium salt of the acidndi-naphthalene methanesulfonic acid, and sulfitization or optional pigment separationnin the presence of an addition product of ethylene oxide to a mixture of unsaturated alcoholsnand saturated, at a temperature of 75-85 ° C, the obtained pigment being filtered,nit is washed with water at a similar temperature and possibly dried. |
