purpose | for the preparation of dyes, pesticides and rubber antioxidant, etc. The product is for dyes, pesticides, rubber additives and other intermediates in organic synthesis. used in dye, pharmaceutical industry, also used as rubber antioxidant |
production method | is obtained from the nitration of naphthalene. In practical industrial production, a portion of the mixed acid required for the reaction can be reused. 600kg of the spent acid obtained from the above batch nitration was added to a glass-lined reaction pan, and under cooling, 98% of 100% sulfuric acid and of nitric acid were further added thereto, followed by stirring to prepare a mixed acid for use. 800kg of the last nitrated waste acid was added to the reaction pot, and 1550kg of refined naphthalene and the mixed acid prepared above were added. The refined naphthalene and the mixed acid were added three times, and the temperature was controlled at 50-55 °c. After addition, the temperature was raised to 65 ℃ for 3H. When the freezing point is ≥ 51 ℃, nitrifying waste acid is separated. The reaction was washed to neutrality with hot water to give 1-nitronaphthalene. |
