| titleOfInvention | The purification process of the pigment of hydroxyl |
| abstract | The present invention discloses the purification process of the pigment of a kind of hydroxyl, and technique is simple, and cost is low, it is possible to industrialization is produced. Through gelatinization and autoclaving, starch emulsion is obtained starch paste, and gained starch paste mixes with the pigment aqueous solution of hydroxyl, aging, obtains the glue shape containing pigment and brings back to life starch; Adding alpha-amylase by bringing back to life containing the glue shape of pigment in starch, make the amylorrhexis not participating in bringing back to life, supernatant liquor is outwelled in separation, gets precipitation washing, the starch of bringing back to life of hydroxyl pigment after obtaining purifying; Being dissolved in high alkali liquid, the starch that makes to bring back to life opens hydrogen bond, becomes water soluble starch, and discharges the pigment of hydroxyl, regulates pH to be 7.0, makes alkali lye be neutralized into salt; Use alcohol settling starch wherein, get the solution of hydroxyl pigment, gained solution through concentrating, be dried to solid; Solid vibrations process, and sieving separating block crystallization wherein, lower floor's powder is the pigment powder after purifying. The method removes impurity according to containing hydroxyl, can industrialization produce. |
