    摘要: The invention relates to prepolymers for native epoxide resins that can be used on an industrial scale or in the various areas of everyday life, e.g. as coating materials or adhesives. The invention also relates to a method for producing these prepolymers. The aim of the invention is to provide substances that are suitable as prepolymers, that are suitable for obtaining native epoxide resins and that can be produced without safety hazards at economical costs. According to the invention, polyhydroxy-polyepoxy fatty acid alkyl ester ethers are used as the prepolymers. They belong to a class of substances that comprises oxirane rings, ether compounds and OH groups, and that therefore correspond to the synthetic resin components to a high degree. According to the inventive method, fatty alkylesters are epoxidized with hydrogen peroxide under the influence of performic acid at a temperature of from 70 °C to 90 °C. A part of the epoxides produced immediately reacts to polyhydroxyethers. The product mixtures so produced are removed from the acid water at a temperature of approximately 65 °C using fine-meshed wire nettings. The remainder of the acid water is removed by vacuum evaporation.

    摘要: Au cours d'un procédé à plusieurs étapes d'époxydation continue de doubles liaisons d'oléfines situées centralement ou en bout de chaîne, comportant plus de 12 atomes de C, des acides gras non saturés et leurs esters, ainsi que des alcools non saturés dont le radical alcoyle comporte de 8 à 18, de préférence 18, atomes de C, et des triglycérides, de préférence de l'huile de soya, avec utilisation d'acide performique formé in situ à partir du peroxyde d'hydrogène et de l'acide formique, on amène les réactants, oléfine et peroxyde d'hydrogène/acide formique, à une réaction en cascade composée d'au moins 3 étapes à pression atmosphérique dans un contre-courant en croix. La phase oléfinique est ainsi placée dans la première étape de réaction, le peroxyde d'hydrogène et l'acide formique sont ajoutés en écoulements séparés à l'avant dernière étape de réaction et les phases oléfine et peroxyde d'hydrogène/acide formique (phase eau acidulée) sont séparées l'une de l'autre après chaque étape de réaction dans un séparateur de phases. La phase contenant l'oléfine passe successivement par les étapes de réaction I à n, alors que l'eau acidulée après l'étape de réaction (n - 1) passe par les étapes de réaction (n - 2) à II en sens inverse de la phase oléfine, et finalement par les étapes n et I; la température de réaction se situe entre 50 et 80oC dans les réacteurs, mais entre 15 et 60oC dans les séparateurs de phases.
