Abstract: The object of the invention is to specify a process with which both C5 and C9 aldehydes can be produced economically. Here, the process should be able to to be supplied with the lowest possible dependence on raw material suppliers and also should be able to react flexibly to fluctuations in demand with respect to C5 and C9 aldehydes. The use of resources should also be optimized. The process proposed uses LPG or NGL as raw material. The process according to the invention essentially differs from known LPG-based processes in that the intermediate obtained, after dehydrogenation and removal of by-products, is divided into two portions. C9 aldehyde is produced from the first portion by oligomerization and hydroformylation while C5 aldehyde is obtained by hydroformylation of the second portion. This has the critical advantage that it is possible to divide the intermediate flexibly into the two portions so that either more C5 or more C9 aldehydes can be produced depending on the respective demand.

Abstract: The invention is concerned with the production of 1-hexene and octenes from ethene 1-Butene is optionally also to be produced The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE ethenfication to achieve better chemical utilization of the employed carbon atoms This problem is solved by catalytic retrocleavage of MTHxE into the C6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C6 olefins with ethene to afford C8 olefins In this way the alcohol is not lost from the process but rather is internally recirculated as a denvatizing agent The less attractive C6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product

Abstract: Se describe un proceso OCTOL el cual mediante la limitación de la conversión en sus etapas de oligomerización individuales se elabora particularmente para la utilización productiva de mezclas de materia prima de C4 con un bajo contenido de 1-buteno y el cual sin embargo produce una mezcla de producto de C8 que tiene un índice Iso adecuado para la preparación de alcoholes plastificantes.

Abstract: La preparación de alcoholes de alta calidad del proceso oxo, de fuentes de materias primas no constantes es el problema técnicamente demandante tratado por esta invención. Se relaciona con un proceso para preparar de manera continua una mezcla de alcoholes, en el cual, una mezcla de entrada que comprende olefinas y que tiene una composición que cambia con el tiempo, se somete a una oligomerización para obtener un oligomerizado y al menos una porción de los oligómeros de olefina presentes en el oligomerizado se hidroformila con monóxido de carbono e hidrógeno en una hidroformilación, en la presencia de un sistema de catalizador homogéneo para proporcionar aldehídos, al menos algunos de los cuales se convierten a la mezcla de alcohol mediante la hidrogenación subsiguiente. Más particularmente, el problema tratado por la invención es aquél de especificar un proceso tal, que permita que se produzca una calidad constante del plastificante durante un periodo de producción largo y, si se requiere, se habilite un rendimiento más alto con la misma calidad del producto. Esto se logra • mediante el control de la temperatura y/o la conversión de la oligomerización, como una función de la composición actual del oligomerizado;.

Abstract: The invention relates to an OCTOL process, which, because of the limitation of the reaction in individual oligomerization steps of the OCTOL process, is designed particularly for the processing of C4 feed mixtures having a low 1-butene content and which nevertheless provides a C8 product mixture having an iso index suitable for the production of plasticizer alcohols.

Abstract: The invention relates to a process for increasing the selectivity of the hydrogenation of 4,4'-diaminodiphenylmethane (4,4'-MDA) to diaminodicyclohexylmethane (4,4'-HMDA) by catalytic hydrogenation of a mixture containing 4,4'-MDA as the main component and its mono-N-methyl derivative as a secondary component. According to the invention, the hydrogenation is terminated before a conversion of 4,4'-MDA to 4,4'-HMDA of 99% is achieved. Under these conditions, a substantially smaller proportion of the N-methyl-4,4'-MDA is hydrogenated to N-methyl-4,4-HMDA.
