| 20110152596 | CATALYST AND PROCESS FOR PREPARING ISOOLEFINS - A catalyst, useful in the preparation of isoolefins and containing 0.1 to 20% by mass of an alkali metal oxide, an alkaline earth metal oxide and mixtures thereof; 0.1 to 99% by mass of aluminum oxide; and 0.1 to 99% by mass of silicon dioxide, is prepared by a) treating an aluminosilicate with an aqueous alkali metal salt solution, an alkaline earth metal salt solution and mixtures thereof, under acidic conditions, to obtain a treated aluminosilicate; and b) calcining the treated aluminosilicate, to obtain the catalyst. | 06-23-2011 |
| 20100197983 | METHOD FOR THE PRODUCTION OF UNBRANCHED ACYCLIC OCTACTRIENES - The invention relates to the preparation of one or more unbranched acyclic octatriene(s) by dimerization of 1,3-butadiene in the presence of a catalyst comprising a carbene ligand and an element of transition group VIII of the Periodic Table of the Elements as metal. | 08-05-2010 |
| 20100144998 | PROCESS FOR FINE PURIFICATION OF 1-BUTENIC STREAMS - The invention relates to a process for preparing 1-butenic fractions having less than 2000 ppm of isobutene in relation to 1-butene from technical mixtures of C | 06-10-2010 |
| 20100137486 | MIXTURE OF ALICYCLIC POLYCARBOXYLIC ESTERS HAVING HIGH CIS CONTENT - The present invention relates to mixtures of alicyclic polycarboxylic esters with high cis content, to a process for their preparation by ring-hydrogenation of the corresponding aromatic polycarboxylic esters, and also to the use of the mixtures. | 06-03-2010 |
| 20090054710 | METHOD FOR THE TELOMERIZATION OF NON-CYCLIC OLEFINS - Process for telomerizing noncyclic olefins having at least two conjugated double bonds with at least one nucleophile using a catalyst containing a metal of group 8, 9 or 10 of the Periodic Table of the Elements, wherein the overall telomerization process has a process step of catalyst recycling, in which hydrogen is added via a hydrogen source to the mixture present in this process step. | 02-26-2009 |
| 20080245996 | METHOD FOR PRODUCING BENZOIC ACID ESTERS - A process for preparing benzoic esters whose alkoxy groups have from 7 to 13 carbon atoms by reacting benzoic acid with at least one alcohol having from 7 to 13 carbon atoms, the water of reaction formed being removed during the esterification reaction by distillation, and the alcohol not converted in the esterification reaction being removed after the esterification reaction, in which the reaction takes place in the presence of a tin(II) compound as catalyst and, without treatment with a base, the catalyst and/or its derivatives is/are separated off by filtering or by centrifuging from the reaction mixture which remains after the unconverted alcohol has been separated off. | 10-09-2008 |
