Abstract
Abstract A new method is proposed for determination of the residue of 1,4,7‐trioxacyclotridecane‐8‐13‐dione in the polyester polymer used for production of elastic polyurethane foams, which in turn are widely used in car industry. This compound is responsible, among other factors, for the phenomenon of fogging up of internal car windows. The method is based on extraction of the residue from the polyester, followed by HPLC analysis with a refractive index detector. In the paper, the procedures of isolation, identification, and purification of the compound are described. Some results are given of determination of 1,4,7‐trioxacyclotridecane‐8‐13‐dione in samples of polyester with different contents of the analyte. The proposed method is characterised by high precision, permitting the determination of 0.025% of the compound residue in the polymer.
The proposed method accurately determines 1,4,7-trioxacyclotridecane-8-13-dione residue in polyester polymers, enabling the production of elastic polyurethane foams for car interiors.
