This book was released on 1964 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans la première partie de ce travail, nous décrivons les procédés de purification des substances de départ et le montage expérimental utilisé pour étudier la photo-oxydation de l'heptaldéhyde. A côté des méthodes très classiques de dosage chimique, nous avons utilisé le technique analytique de la spectrographie infra-rouge, pour suivre l'évolution du mélange réactionnel en cours de photo-oxydation, identifier les produits de réaction et déterminer leurs structures. Dans une troisième partie, nous présentons nos résultats relatifs à l'étude de la vitesse et du mécanisme de la réaction à l'instant initial. Enfin, dans une quatrième partie, nous examinons l'allure de la réaction en fonction du temps au cours d'une expérience, et nous cherchons à préciser les complications qui apparaissent alors dans le mécanisme de la réaction globale.

Book excerpt: CE TRAVAIL DE THESE CONCERNE LA STABILITE ET LA REACTIVITE (ETUDES CINETIQUES) DE RADICAUX LIBRES FORMES LORS DES PROCESSUS D'OXYDATION DES COMPOSES AROMATIQUES EN PHASE GAZEUSE. CES PROCESSUS SONT ENCORE MAL CONNUS, TANT DU POINT DE VUE CINETIQUE QUE MECANISTIQUE, ET DE TELLES DONNEES MANQUENT DANS LES MODELES DE SIMULATION DE LA CHIMIE ATMOSPHERIQUE. LA PARTIE EXPERIMENTALE A ETE EFFECTUEE AU MOYEN D'UN APPAREILLAGE DE PHOTOLYSE ECLAIR COUPLE A UNE DETECTION DES RADICAUX LIBRES PAR SPECTROMETRIE D'ABSORPTION UV. LA PREMIERE PARTIE CONCERNE LA STABILITE ET LA REACTIVITE DE RADICAUX DE TYPE CYCLOHEXADIENYLE, FORMES PAR L'ADDITION D'UN ATOME OU RADICAL SUR LE NOYAU AROMATIQUE DU BENZENE. LES RESULTATS OBTENUS DANS LE CAS DU BENZENE DEVRAIENT ETRE REPRESENTATIFS DE LA REACTIVITE DU MEME ATOME OU RADICAL VIS-A-VIS DU CYCLE AROMATIQUE DANS D'AUTRES COMPOSES. NOUS AVONS ETUDIE EXPERIMENTALEMENT LA STABILITE ET LA REACTIVITE AVEC O#2 DES RADICAUX CLC#6H#6 ET C#6H#7, AINSI QUE LA REACTIVITE DU RADICAL C#6H#7 AVEC NO. NOUS AVONS COMPLETE CES RESULTATS EXPERIMENTAUX PAR DES CALCULS QUANTIQUES VISANT A ETABLIR LA STABILITE RELATIVE D'UNE SERIE DE RADICAUX XC#6H#6 (X = F, CL, BR, H, OH). LES RESULTATS OBTENUS PAR CES DEUX APPROCHES, EXPERIMENTALE ET THEORIQUE, SONT EN BON ACCORD. LA DEUXIEME PARTIE CONCERNE LE RADICAL PHENOXYLE FORME LORS DE L'OXYDATION DU PHENOL, COMPOSE DIRECTEMENT EMIS DANS L'ATMOSPHERE ET FORME LORS DE L'OXYDATION DU BENZENE DANS L'AIR.

This book was released on 1955 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: On détermine les conséquences cinétiques du mécanisme d'oxydation lente, en phase gazeuse, obtenu en introduisant, dans le schéma de Niclause, Combe et Letort (1951-53), deux variantes de radicaux libres du processus d'initiation auto-catalytique (production de radicaux libres à partir de l'hydroperoxyde ROOH formé), qui avait été supposé initialement monomoléculaire. Pour vérifier ce mécanisme et pour préciser la nature exacte du processus d'initiation autocatalytique, on effectue une nouvelle étude systématique de l'oxydation lente des aldéhydes acétique et proprionique gazeux. On examine en outre les complications qui peuvent intervenir à haute température (instabilité du peracide, pyrolyse induite ... ).
