"The composition of branched primary alcohol, process for preparing the same, branched primary alcohol composition of branched primary alcohol, alcoxilada,Alcoxilada branched primary alkyl sulfate, alkyl carboxylate primary branched and detergent composition ''.Provides is a new composition of branched primary alcohol, and their sulfates, alcoxilatos, alcu00f3xi sulphates and carboxylates, presenting good detergent and biodegradability in cold water.The composition of branched primary alcohol has an average number of branches per chain of 0.7 to 3.0, having at least 8 carbon atoms and containing both methyl ethyl branches, as well as.The composition of primary alcohol may also contain less than 0.5% by atom of quaternary carbon atoms, and a significant number of ethyl branches.Ramifications of isopropyl terminal, branching off at the position C ~ 3 ~ in relation to carbon hidroxu00edlico.Process for the manufacture of a structural isomerization is by feeding of olefin having at least 7 carbon atoms or by dimming of an olefin C ~ 6 ~ C ~ 10 ~,Followed by conversion to an alcohol, through hidroformilau00e7u00e3o, and finally alcoxilau00e7u00e3o sulphation, or both, to produce a surfactant detergent.Structural isomerization catalysts useful include zeolites having at least one channel with a diameter cristalogru00e1fico free over the plans X and / or y of view [001]Ranging from 42 to 70 nm.Catalysts of dimer formation useful include a combination of a nickel carboxylate with aluminados alkyl halides.Or a combination of a nickel chelate with a alcu00f3xido aluminado alkyl.
