Description
Technical field
The present invention relates to the production method of a kind of high purity 2-amino-α-Nai Huangsuan (TOBIAS ACID 97MIN.﹠ 98MIN.), particularly, is the removal and the refining preparation method who purifies of TOBIAS ACID 97MIN.﹠ 98MIN. of the impurity 2-naphthylamines in the TOBIAS ACID 97MIN.﹠ 98MIN. production process.
Background technology
TOBIAS ACID 97MIN.﹠ 98MIN. is a kind of dyestuff intermediate, and the production technique of TOBIAS ACID 97MIN.﹠ 98MIN. mainly is in the world at present: the beta naphthal that will be dissolved in o-nitroethylbenzene is by chlorsulfonic acid sulfonation production 2-hydroxyl-α-Nai Huangsuan; With obtaining 2-hydroxyl-α-Nai Huangsuan sodium with separating in the soda ash; Liquefied ammonia ammonia in the presence of acid ammonium sulphite is separated, obtained 2-amino-α-Nai Huangsuan sodium; Make with hcl acidifying again.In the TOBIAS ACID 97MIN.﹠ 98MIN. of gained, the 2-naphthylamines is the detrimental impurity that must contain.The 2-naphthylamines is a kind of strong carcinogens, and there is strict demand in developed countries such as America and Europe to the 2-naphthylamines in the TOBIAS ACID 97MIN.﹠ 98MIN., and general requirement 2-naphthylamines content is lower than 50ppm.So the content that how to reduce 2-naphthylamines in the TOBIAS ACID 97MIN.﹠ 98MIN. product is a problem that needs solution during TOBIAS ACID 97MIN.﹠ 98MIN. is produced.
Summary of the invention
The objective of the invention is to remove wherein impurity 2-naphthylamines, thereby a kind of process for refining and purifying of high-quality TOBIAS ACID 97MIN.﹠ 98MIN. is provided by in traditional TOBIAS ACID 97MIN.﹠ 98MIN. production technique, setting up absorbing process.
Technical scheme of the present invention is as follows:
A kind of production method of 2-amino-α-Nai Huangsuan, it comprises the steps: that the sulfonation of beta naphthal obtains 2-hydroxyl-α-Nai Huangsuan sodium, ammonia is separated and is obtained 2-amino-α-Nai Huangsuan sodium then, last acidifying obtains 2-amino-α-Nai Huangsuan, the invention is characterized in after ammonia is separated step, increase following steps:
A) after the ammonification operation of 2-amino-α-Nai Huangsuan traditional processing technology, with mother liquor from amination 0～60 ℃ and flow be under 0.5～5BV/h (BV is the resin bed volume) condition by being filled with vinylbenzene-divinylbenzene copolymerization macroporous resin and having the adsorption tower of insulation jacket, the 2-naphthylamines is attracted on the macroporous resin.This step can reach more than 90% the clearance of 2-naphthylamines, the mother liquor after the purification traditionally through acidifying, make 2-amino-α-Nai Huangsuan of 2-naphthylamines content≤50ppm after getting rid of filter;
B) macroporous resin that steps A has been carried out absorption is that 1～10% the NaOH aqueous solution and water are made regenerator with concentration earlier, regenerate, at first 2-amino-α-Nai Huangsuan is eluted, eluting temperature is 20～90 ℃, the wash-out flow is 0.5～5BV/h, and alkaline eluant returns acidizing process and reclaims product;
C) (wherein HCl concentration is 2～10% to use hydrochloric acid-methyl alcohol or ethanolic soln again, methyl alcohol or ethanol content are 30～60%) and water make regenerator, carry out regenerative elution, the 2-naphthylamines that is adsorbed on the resin is eluted, the wash-out flow is 0.5～5BV/h, eluting temperature is 30～50 ℃, and this elutriant can carry out burning disposal;
D) macroporous resin after the regeneration is handled the mother liquor after ammonia is separated once more.
In the above-mentioned method, described macroporous adsorbent resin is CHA-101 resin, H-103 resin or Amberlite XAD-4 resin.
Adopt the present invention that the 2-naphthylamines content in 2-amino-α-Nai Huangsuan mother liquor from amination is reduced to below the 100mg/L from about 1500mg/L, after traditional acidifying, get rid of filtering technology and can make 2-amino-α-Nai Huangsuan product that 2-naphthylamines content is lower than 50ppm.
