裂解气相色谱测定芳香织物的逸香速率

Test of Discharging Rate of Perfume Compounds on Fabrics by Capillary Gas Chromatography

采用一种裂解气相色谱法测定了芳香织物的逸香速率.采用居里点裂解器将芳香织物裂解,用毛细管柱气相色谱分离检测;以香精裂解代表组分、织物裂解代表组分的比值(Ai／Ak)来表示织物上香精含量C,测定不同时间织物上的香精含量,通过lnC-t求得逸香速率常数,算出释香半衰期为7 d.

Established an analytical method for testing discharging rate of perfume compounds on fabrics. Curie-point pyrolyzer was used to crack the sample of fabrics and the perfume compositions were tested at the same time. The ratio of the maximum peak area of cracking products of essence on the sample to the maximum peak area of pyrolysis products of fabrics was used to stand for the content of perfumery compounds on the fabrics. Then half-life period of essence on the fabrics could be calculated.
