Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.

| Résumé : |
A disadvantage of chamois leather tanning practiced nowadays is that its oxidation process takes relatively long time, i.e. 9 to 14 days. The use of an oxidizing agent, such as sodium percarbonate was reported to shorten the tanning oxidation process. However, the price of this oxidizing agent is relatively high; a constraint in its application. Other oxidizing agents, such as hydrogen peroxide, may have the same function of accelerating the process. The objectives of this study were to investigate the effects of type and concentration of oxidizing agents in order to obtain the optimum combination of process acceleration and chamois leather characteristics. This study consisted of the leather tanning with rubber seed oil with oil oxidation comparing two types of oxidizing agents at three concentrations of each oxidizing agents; testing of physical, chemical, and organoleptic properties of the leathers, and microscopic studies of the leathers. The results of this study indicate that hydrogen peroxide could be used as oxidizing agents for the chamois leather manufacture, since the chamois leather produced met the quality standards. The best treatment of this trial was hydrogen peroxide at 6% (w/w based on of the weight of rubber seed oil applied). The use of hydrogen peroxide could shorten the oxidation process from 9-14 days to about three days. |
