Absorption
AldéhydesUn aldéhyde est un composé organique, faisant partie de la famille des composés carbonylés, dont l'un des atomes de carbone primaire (relié au plus à 1 atome de carbone) de la chaîne carbonée porte un groupement carbonyle.
L'aldéhyde le plus simple est le formaldéhyde (ou méthanal), aussi appelé formol lorsqu'il est en solution aqueuse.
Un aldéhyde dérive formellement d'un alcool primaire (oxydation) dont le groupement hydroxyde -OH est en bout de chaîne et se forme suite à l'enlèvement de deux atomes H d'où le nom "alcool déshydrogéné" ou aldéhyde.

| Résumé : |
In this paper, volatile low molecular weight aldehydes and ketones in samples of leather shoes were collected by static absorption with water, analyzed and detected by 2,4dinitrophenylhydrazine pre-column derivatization of high performance liquid chromatography (HPLC). Firstly, the sampling temperature and lime of the volatile aldehyde and ketone in leather shoes were optimized and then the volatile aldehyde and ketone in absorption liquid were determined. The experiment result shows that the optimal temperature is 45°C, the sampling time is 24 hours. The collected sample was derivatized by purified sulfuric acid acidulated 2,4dinitrophenylhydrazine. The volatile aldehydes and ketones in absorption liquid of leather shoes were formaldehyde, acetaldehyde, acetone propionaldehyde, butyraldehyde, benzaIdehycle, cyclohexanone and hexanal the average concentrations of which are : 0.252mg/shoe, 0.061mg/shoe, 0.079mg/shoe, 0.053mg/shoe, 0.037mg/shoe, 0.011mg/shoe, 0.09mg/shoe, 0.018mgishoe respectively. This method is suitable for determination of volatile aldehydes and ketones in leather shoes.
