    摘要: Process for the treatment of a material comprising a polymer, especially a polyamide. The process consists in subjecting the polyamide to hydrolysis in the presence of a hydrolyzing nitrous grouping and transforming the hydrolyzed compounds into diacids. The treatment of a polyamide 6.6 results in the recovery of adipic acid and other diacids corresponding to the participating acid monomer and to the transformation of at least one part of the diamine monomer into diacids.

    摘要: The visual form of data from a computer program is received and stored in a database. The visual form of the data may be received, for example, in response to a print operation by the computer program or by some other operation such as a cut and paste sequence of operations or by sending the data to another application. The visual form of the data may be stored as a vector image that permits scalability. The visual form of the data may be stored with other identifying information or tags in the database to facilitate searching of the database. The data in the database may be encoded in a manner that ensures data integrity and that permits detection of when data has been compromised. In one embodiment, a service layer application is provided to control access to the database by performing encoding and decoding of the data in the database. The service layer may have an application programming interface that permits many applications to have access to the database. Another application may be provided for accessing the visual form of the data from the database and for providing this data to another computer program. Such an application permits a user to create compound documents from data in the database using the other computer program.

    摘要: The present invention relates to a process for the preparation of carboxylic acids from unsaturated fatty acids and/or their derivatives.The process of the invention is characterized in that it comprises the following stages:a stage which consists in oxidizing an unsaturated fatty acid in the form of acid and/or of ester using hydrogen peroxide, in the presence of a metal oxide or of a carboxylic acid optionally used in combination with a ruthenium-based catalyst,a stage which consists in reacting the reaction mixture originating from the preceding stage with nitric acid in the presence of a vanadium-based catalyst, optionally used in combination with a cocatalyst, and thena stage of recovery of the mono- and dicarboxylic acids.It is particularly well suited for the preparation of saturated mono- and dicarboxylic acids obtained from unsaturated fatty acids such as oleic acid or from oils and fats.
