AI Technical Summary
Existing 2-aminoethanol hydrogen sulfate products have small particle size and are prone to agglomeration. They are also prone to moisture absorption during storage and transportation, resulting in poor flowability, which affects the filtration and separation process. Furthermore, the preparation process poses safety risks and high energy consumption.
By preparing seed slurry, dehydrating and esterifying, and crystallizing and growing crystals, adding spherical additives and anti-caking agents, controlling the crystallization process, and optimizing temperature and stirring rate, 2-aminoethanol hydrogen sulfate crystals with large particle size and high sphericity are prepared.
2-Aminoethanol hydrogen sulfate with large and uniform particle size, high sphericity, and excellent anti-caking properties was obtained, which improved crystallization efficiency, reduced production energy consumption, and avoided product agglomeration and bridging.
