    Abstract: Integrated process, in which pure carbonyl iron powder (CIP) is prepared by decomposition of pure iron pentacarbonyl (IPC) in a plant A, carbon monoxide (CO) liberated in the decomposition of the IPC is used in plant A for the preparation of further CIP from iron or is fed to an associated plant B for the preparation of synthesis gas or is fed to an associated plant C for the preparation of hydrocarbons from synthesis gas, and the CIP prepared in plant A is used as catalyst or catalyst component in an associated plant C for the preparation of hydrocarbons from synthesis gas from plant B.

    Abstract: La invención se refiere a un método para producir sales del ácido acrilamido-2-metilpropan sulfónico (A), que consiste en los siguientes pasos: a) producir una solución de una sal contaminada del ácido acrilamido-2-metilpropan sulfónico (A) en un solvente orgánico libre de agua (L) utilizando al menos un componente básico (8) seleccionado del grupo que consiste en óxidos de metales alcalinos, óxidos de metales alcalinotérreos, hidróxidos alcalinos, hidróxidos de metales alcalinotérreos y aminas de fórmula general (I) NRaRbRC (I), en donde los grupos Ra, Rb y Rc, independientes entre sí, significan lo siguiente: hidrógeno, alquilo de C1-C4, hidroxialquilo de C1-C4 o alcoxi de C1-C4, en donde la relación molar del compuesto (A) al compuesto básico (B) es preferentemente 1:1 a 1:3; b) eliminar, como una opción, parcialmente el solvente orgánico (L) a una presión en el intervalo de 0.001 a 2 bares (abs); c) recuperar la sal disuelta del compuesto (A) por cristalización o precipitación, cambiando la temperatura y/o la presión y/o la concentración de la sal en la solución; d) como una opción secar la sal purificada del ácido acrilamido-2-metilpropan sulfónico (A). Dicho método de acuerdo con la invención permite obtener sales pobre en subproductos y especialmente apropiadas para la polimerización.

    Abstract: 1 4 METHOD FOR CHANGING THE PREDEFINED MEAN MOLECULAR WEIGHT MN DURING THE CONTINUOUS PRODUCTION OF POLYTETRAHYDROFURANES OR THF COPOLYMERS 5 THE OBJECT OF THE PRESENT INVENTION IS A METHOD FOR CHANGING THE PREDEFINED MEAN MOLECULAR WEIGHT MN DURING THE CONTINUOUS PRODUCTION OF POLYTETRAHYDROFURANE, OR TETRAHYDROFURANE COPOLYMERS, THE MONOESTERS OR DIESTERS OF POLYTETRAHYDROFURANE. OR TETRAHYDROFURANE COPOLYMERS. BY THE POLYMERIZATION OF TETRAHYDROFURANE IN THE PRESENCE OF TELOGEN AND/OR A COMONORNER ON AN ACID 10 CATALYST, WHEREIN: A) THE MOL RATIO OF TELOGEN TO TETROHYDROFURANE, OR TO TETRAHYDROFURANE AND THE COMONOMER, IS CHANGED, B) THEN THE MEAN MOLECULAR WEIGHT OF AT LEAST ONE SAMPLE IS DETERMINED, C) AS LONG AS THE MEAN MOLECULAR WEIGHT DETERMINED IN THIS WAY DEVIATES FROM THE MOLECULAR WEIGHT TO BE ACHIEVED BY THE CHANGE, THE PREVIOUSLY FORMED POLYTETRAHYDROFURANE, OR THE 15 TETRAHYDROFURANE COPOLYMERS, THE MONOESTERS OR DIESTERS OF THE POLYTETRAHYDROFURANE, OR TETRAHYDROFURANE COPOLYMERS, ARE AT LEAST PARTIALLY DEPOLYMERIZED ON AN ACID CATALYST, AND D) THE TETRAHYDROFURANE RECAPTURED BY MEANS OF DEPOLYMERIZATION IS RETURNED AT LEAST PARTIALLY TO THE POLYMERIZATION PROCESS.
