YieldReaction ConditionsOperation in experiment
A-1-1, add a small amount of bottom water in the beaker,100%2-naphthylamine-1 sulfonic acid (ie,22.3 g in NaHCO3And pH = 7.0 or so, standby.A-1-2,Add a small amount of ice water in the beaker and ice mill additives,Then add 100% cyanuric chloride 18.5 g,Mix the material.A solution of 2-naphthylamine-1-sulfonic acid was added dropwise,T = 0-5 C,PH = 4.0 to 5.0,Drop finished,Then reacted for 5 hours,21.0 g of sodium 2,4-diaminobenzenesulfonate was added to the monohydrate,Adjust T = 25-30 ,PH = 6.0-7.0, reaction for 6 hours,Get dipped,spare.A step will be obtained in the condensation substance added in the solution 30% hydrochloric acid solution, ice and sodium nitrite solution. In the 0 - 5 C, pH _aoltao_ 2.0 conditions, reaction 2 hours (using starch potassium iodide paper after dipping the micro blue, NaNO2micro excessive), sulfamic acid eliminate excess nitrous acid. To be coupled.C-1-1,Add a small amount of bottom water in the beaker,100% 3-formylamino-4-methyl-6-hydroxy-N-ethylpyridone 19.6 g,Neutralize with pH = 6.0-7.0 with NaHCO3.C-1-2,A solution of 3-carbamoyl-4-methyl-6-hydroxy-N-ethylpyridone was added to the diazonium salt in step b,With Na2CO3 adjusted pH = 7.0 or so,Heating up,Maintain the temperature T = 25-30 ,Maintain pH = 7.0-8.0,The reaction was carried out for 6 hours. The dye was added 5% of the carbon powder for 2 hours, filtered, the filtrate.The filtrate and then a number of membrane filtration, desalination.Adding the d-step dye to the feed liquid preheater and adjusting the spray tower inlet temperature for spray drying.
