This book was released on 1990 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: LA CHROMATOGRAPHIE EN PHASE SUPERCRITIQUE (CPS) PERMET, NON SEULEMENT LA SEPARATION DE COMPOSES NON VOLATILS ET/OU THERMOLABILES AVEC DE TRES HAUTES EFFICACITES MAIS AUSSI LE COUPLAGE AVEC DE NOMBREUX DETECTEURS DONT L'INFRAROUGE A TRANSFORMEE DE FOURIER. LE DIOXYDE DE CARBONE PRESENTE DE LARGES FENETRES DE TRANSPARENCE EN IR, MAIS CERTAINES VIBRATIONS SONT NON DETECTEES. LE MEILLEUR FLUIDE POUR LA CPS-IRTF EST LE XENON, MAIS EN RAISON DE SON FAIBLE POUVOIR ELUANT, SON UTILITE RESTE LIMITEE. POUR FAVORISER L'ELUTION DES PRODUITS POLAIRES, SOIT ON AJOUTE UNE FAIBLE QUANTITE DE MODIFICATEURS POLAIRES AU CO#2, CE QUI N'EST PAS SANS CONSEQUENCE SUR LA TRANSPARENCE IR DE LA PHASE MOBILE; SOIT ON UTILISE UNE PHASE STATIONNAIRE POLYMERE (PRP-1) SANS GROUPEMENT SILANOL. UNE ETUDE DU MECANISME DE RETENTION SUR UNE FAMILLE DE COUMARINES A PERMIS DE CONCLURE SUR LE TYPE D'INTERACTIONS MISES EN UVRE LORS DE L'ELUTION ET DE DEFINIR UNE ECHELLE ELUOTROPIQUE DIFFERENTE DE CELLE OBTENUE SUR C18. LE COUPLAGE CPS-IRTF A ETE APPLIQUE, EN PREMIER LIEU, A LA CARACTERISATION D'UN INTERMEDIAIRE REACTIONNEL INTERVENANT LORS DE LA CHLORATION DU TRICHLORO-2,4,6 PHENOL. LES PRINCIPAUX GROUPEMENTS FONCTIONNELS ONT ETE DEDUITS DE IRTF, ET LA STRUCTURE COMPLETE PAR LA SPECTROMETRIE DE MASSE (SM) ET LA RMN. DEUXIEMEMENT, LES SESQUITERPENES D'UNE HUILE ESSENTIELLE DE POIVRE ONT ETE IDENTIFIES GRACE A CETTE TECHNIQUE. APRES UN PREFRACTIONNEMENT PAR CHROMATOGRAPHIE LIQUIDE SEMI-PREPARATIVE, L'ANALYSE PAR CPS-IRTF AVEC DES MICROCOLONNES A PERMIS D'IDENTIFIER 42 CONSTITUANTS DE L'HUILE EN COMPLEMENTARITE AVEC LA SM

This book was released on 1992 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL CONCERNE L'UTILISATION DES COLONNES CAPILLAIRES DANS LE CADRE DE TROIS DIFFERENTS COUPLAGES: LE DETECTEUR A IONISATION DE FLAMME (DIF), LE SPECTROMETRE INFRAROUGE A TRANSFORMEE DE FOURIER (IRTF) ET LE SPECTROMETRE DE MASSE (SM), AVEC DU DIOXYDE DE CARBONE (CO#2) PUR, APPLIQUES A L'ANALYSE DE POLYSILOXANES ET DE FLAVONOIDES. LES PREMIERS ESSAIS ONT PERMIS DE METTRE L'ACCENT SUR UN POINT TECHNOLOGIQUE INDISPENSABLE MAIS DELICAT: LE RESTRICTEUR, QUI ASSURE LA DETENTE ENDOTHERMIQUE DE LA PHASE MOBILE DE L'ETAT SUPERCRITIQUE A L'ETAT GAZEUX; LES RESTRICTEURS CAPILLAIRES CLASSIQUES PRESENTENT DES RISQUES DE BOUCHAGE POUR L'ANALYSE DE COMPOSES POLAIRES OU DE MASSES ELEVEES (GENERALEMENT SUPERIEURES A 2000 U.M.A.). NOUS EN SOMMES VENUS A PROPOSER UN NOUVEAU TYPE DE RESTRICTION: LA RESTRICTION PNEUMATIQUE, SON PRINCIPE ETANT BASE SUR L'AJOUT CONTROLE D'UN GAZ ADDITIONNEL, EN AMONT D'UN RESTRICTEUR CAPILLAIRE PLUS COURT ET DE DIAMETRE PLUS ELEVE QUE LES RESTRICTEURS COURAMMENT UTILISES; CE SYSTEME PRESENTE DEUX ATOUTS MAJEURS: DIMINUTION DES RISQUES DE BOUCHAGE, INDEPENDANCE DES REGULATIONS DE DEBIT ET DE PRESSION. SUR UN PLAN PUREMENT QUANTITATIF, NOUS NOUS SOMMES INTERESSES AU COMPORTEMENT DU DIF AU COURS D'UN GRADIENT D'ELUTION DE CO#2, EN FONCTION DES CONDITIONS DE PRESSION ET DE TEMPERATURE. LES TENDANCES OBSERVEES TRADUISENT UNE AUGMENTATION DE LA SENSIBILITE LORSQUE LA PRESSION AUGMENTE. PAR AILLEURS, LE COUPLAGE CPS-IRTF EN LIGNE, DEVELOPPE INITIALEMENT SUR LES COLONNES REMPLIES, EST ICI TESTE SUR LES COLONNES CAPILLAIRES. L'EXEMPLE DES FLAVONOIDES EST TRAITE AVEC LE CO#2 PUR COMME PHASE MOBILE; AVEC UNE IDENTIFICATION SATISFAISANTE; LES LIMITES ONT ESSENTIELLEMENT PORTE SUR LE CARACTERE APOLAIRE DU CO#2, SE TRADUISANT PAR UNE FORCE ELUANTE INSUFFISANTE POUR L'ANALYSE DES FLAVONOIDES POLYHYDROXYLEES. POUR PRESERVER LA TRANSPARENCE DE LA PHASE MOBILE NECESSAIRE A LA DETECTION INFRA-ROUGE, L'AJOUT DE MODIFICATEURS POLAIRES N'EST, DANS CE CAS, PAS ENVISAGEABLE. SUR LES FLAVONOIDES EGALEMENT, NOUS AVONS TESTE LE COUPLAGE CPS-SM AVEC UNE INTERFACE SIMPLIFIEE (RESTRICTEUR LINEAIRE). LA SENSIBILITE EST DEPENDANTE DES CONDITIONS DE PRESSION DANS LA COLONNE, ENTRAINANT DANS NOTRE CONFIGURATION, DES PRESSIONS MAXIMALES DE L'ORDRE DE 180 BARS POUR MAINTENIR LE VIDE DANS LE SPECTROMETRE DE MASSE. CES LIMITES SONT INSUFFISANTES POUR PERMETTRE A LA CPS DE SUPPLEER LA CHROMATOGRAPHIE GAZEUSE DANS LE DOMAINE DE L'ANALYSE DES COMPOSES PEU VOLATILS. LE CHOIX DU RESTRICTEUR EST ALORS A AFFINER

Book Synopsis Current Topics in Flavours and Fragrances by : K.A. Swift
Download or read book Current Topics in Flavours and Fragrances written by K.A. Swift and published by Springer Science & Business Media. This book was released on 1999-10-31 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to give the reader up to date infonnation on some of the more exciting developments that have taken place at the leading edge of fragrance and flavour research. Chapter one gives the reader a rnpid excursion through the chronological landmarks of fragrance and flavour materials and sets the scene for the remaining nine chapters which cover topics that are at the forefront of modem research. Chapter two looks at the total synthesis of synthetically interesting perfumery naturnl materials. This chapter aims to highlight the creative and elegant chemistry that has been performed by some of the worlds greatest chemists in their quest to synthesise one of the five naturnl products reviewed in the chapter. The chapter fits in with the forward looking theme of the book as it will hopefully inspire other chemists that are interested in synthesising natural products to produce elegant new, or industrially applicable routes to these and other perfumery materials. Chapter three looks at the growing area of interest in asymmetric fragrance materials. The chapter focuses on the use of the metal-BINAP catalytic system for the preparation of fragrance and flavour ingredients. Environmental considerations are now an integrnl and vital part of planning any new industrial chemical process. Chapter four aims to give the reader an insight into the wide-ranging and often readily applicable chemistry that is currently available for the installation of environmentally friendly chemical processes.
Book Synopsis Applied Photochemistry by : Rachel C. Evans
Download or read book Applied Photochemistry written by Rachel C. Evans and published by Springer Science & Business Media. This book was released on 2014-07-08 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Photochemistry encompasses the major applications of the chemical effects resulting from light absorption by atoms and molecules in chemistry, physics, medicine and engineering, and contains contributions from specialists in these key areas. Particular emphasis is placed both on how photochemistry contributes to these disciplines and on what the current developments are. The book starts with a general description of the interaction between light and matter, which provides the general background to photochemistry for non-specialists. The following chapters develop the general synthetic and mechanistic aspects of photochemistry as applied to both organic and inorganic materials, together with types of materials which are useful as light absorbers, emitters, sensitisers, etc. for a wide variety of applications. A detailed discussion is presented on the photochemical processes occurring in the Earth’s atmosphere, including discussion of important current aspects such as ozone depletion. Two important distinct, but interconnected, applications of photochemistry are in photocatalytic treatment of wastes and in solar energy conversion. Semiconductor photochemistry plays an important role in these and is discussed with reference to both of these areas. Free radicals and reactive oxygen species are of major importance in many chemical, biological and medical applications of photochemistry, and are discussed in depth. The following chapters discuss the relevance of using light in medicine, both with various types of phototherapy and in medical diagnostics. The development of optical sensors and probes is closely related to diagnostics, but is also relevant to many other applications, and is discussed separately. Important aspects of applied photochemistry in electronics and imaging, through processes such as photolithography, are discussed and it is shown how this is allowing the increasing miniaturisation of semiconductor devices for a wide variety of electronics applications and the development of nanometer scale devices. The final two chapters provide the basic ideas necessary to set up a photochemical laboratory and to characterise excited states. This book is aimed at those in science, engineering and medicine who are interested in applying photochemistry in a broad spectrum of areas. Each chapter has the basic theories and methods for its particular applications and directs the reader to the current, important literature in the field, making Applied Photochemistry suitable for both the novice and the experienced photochemist.
