Title
(EN) CELLULOSE ACETATE BOUND PHOTOSENSITIZER FOR PRODUCING SINGLET OXYGEN
(FR) PHOTOSENSIBILISATEUR A LIAISON D'ACETATE DE CELLULOSE PRODUISANT DE L'OXYGENE SINGLET
Abstract
(EN) This invention relates to a photosensitizer which is bound to a cellulose acetate polymer, a method of preparing the bound photosensitizer and a process for using the bound photosensitizer. The photosensitizers which may be used in the invention include rose bengal, rhodamine B, acridine orange, methylene blue and zinc phthalocyanine. The photosensitizer is attached to the cellulose acetate by reacting an acid group on the photosensitizer with a hydroxyl group. Finally, the bound photosensitizer may be used to oxidize undesirable oxidizable compounds present in a hydrocarbon or aqueous fraction. One specific example is the sweetening of kerosene which involves oxidizing the mercaptans contained in the kerosene.
(FR) L'invention concerne un photosensibilisateur lié à un polymère d'acétate de cellulose, un procédé de préparation du photosensibilisateur lié ainsi qu'un mode d'utilisation du photosensibilisateur lié. Les photosensibilisateurs utilisables dans l'invention comprennent le rose bengale, la rodamine B, l'orange-acridine, le bleu de méthylène et la phtalocyanine de zinc. Le photosensibilisateur est fixé à l'acétate de cellulose par réaction d'un groupe acide sur le photosensibilisateur avec un groupe hydroxyle. Enfin, on peut utiliser le photosensibilisateur afin d'oxyder des composés oxydables indésirables présents dans une fraction d'hydrocarbure ou aqueuse. Un exemple spécifique est l'adoucissement de kérosène consistant à oxyder les mercaptans contenus dans le kérosène.
