The present invention provides a bio-based succinic acid composition, a preparation method therefor, and a polyester prepared therefrom. The bio-based succinic acid composition includes bio-based succinic acid and a metal ion; and a mass content of the metal ion in the bio-based succinic acid composition is 10-350 ppm. In the present invention, by adopting the bio-based succinic acid composition containing the metal ion as a raw material for the polyester and controlling the content of the metal ion in the bio-based succinic acid composition within a specific range, the obtained polyester has better mechanical properties and heat retention stability.
A bio-based succinic acid composition, comprising bio-based succinic acid and a metal ion, wherein
