Abstract: A process reacts olefins having 4 to 20 carbon atoms and the feed stream used, containing at least linear olefins and branched olefins, is first separated into two streams A and B. Stream A is distilled before the reaction and only the high-boiler phase obtained in this distillation is subjected to the reaction, a heterogeneously catalysed hydroformylation, a homogeneously catalysed hydroformylation or a homogeneously catalysed alkoxycarbonylation.

Abstract: A process produces a carboxylic acid or salt thereof by hydrolysis or saponification of an ester formed by alkoxycarbonylation of diisobutene. The diisobutene stream used in the alkoxycarbonylation is subjected to a distillation prior to the alkoxycarbonylation in order to enrich 2,4,4-trimethylpent-1-ene in the stream to be alkoxycarbonylated. The alkoxycarbonylation is carried out with an alcohol and carbon monoxide in the presence of a homogeneous catalyst system that comprises at least one metal from group 8 to 10 of the periodic table of the elements or a compound thereof, a phosphorus-containing ligand and an acid.

Abstract: A process isomerizes 2,4,4-trimethylpent-2-ene to 2,4,4-trimethylpent-1-ene over a heterogeneous catalyst based on a zeolite or an ion-exchange resin. The process includes providing an input stream containing 2,4,4-trimethylpent-2-ene and 2,4,4-trimethylpent-1-ene and performing the isomerization with the input stream using a heterogeneous catalyst based on a zeolite or an ion-exchange resin. A proportion of 2,4,4-trimethylpent-2-ene in the total stream is at least 25 mol % based on the total input stream.

Abstract: A process provides a tops stream K containing more than 85% by weight of 2,4,4-trimethylpent-1-ene, wherein both an isomerization of 2,4,4-trimethylpont-2-ene to 2,4,4-trimethylpont-1-ene and a distillation to obtain the tops stream K are performed. The isomerization is at least partially fed with the bottoms stream of the distilation where a tops stream K is withdrawn overhead.
