AI Technical Summary
Existing bio-based succinic acid granules are prone to absorbing moisture and clumping during long-term storage, and their small particle size leads to dust and inhalation risks, affecting the performance of downstream applications.
By controlling the crystallization process and employing solvent-temperature controlled crystallization technology, specific D10, D50, and D90 particle size distributions are designed to avoid the use of surfactants and optimize the particle size and purity of bio-based succinic acid particles.
This achieves low moisture absorption of bio-based succinic acid granules, avoiding agglomeration and clumping, improving storage performance and downstream application performance, while ensuring good processing performance and the mechanical properties of polyester.
