Book Description
La catalyse par transfert de phase (CTP) solide liquide sans solvant a été utilisée pour la préparation des nouveaux produits des deux séries de composés d'intérêt biologique. Dans la première partie, l'hypoxanthine et l’adénine ont été alkylées puis plusieurs dérivés de l'adénine préparés. La position d'alkylation a été déterminée par spectroscopie RMN13C. Ces dérivés, comportant une chaine éthoxyméthyle en position 9, sont susceptibles d'avoir des activités antivirales. Dans la deuxième partie, l'acétamidomalonate d'éthyle a été alkylé par des halogénures et des sulfates d'alkyle et par des accepteurs de Michael. Il est ainsi possible de préparer plus simplement que par les méthodes déjà décrites des aminoacides connus, comme par exemple la vinylglycine, inhibiteur d’enzymes. D'autre part, on peut accéder à de nouvelles séries d'aminoacides.

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
