Abstract: The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C 4 -olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.

Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

Abstract: The invention relates to a method for producing formamide by reacting ammonia and carbon monoxide in the presence of at least one catalyst, said catalyst being sodium diformylamide. Sodium diformylamide can, provided that methanolate is used as an additional active component, be produced therefrom. In the corresponding process, sodium diformylamide is an especially active and stable catalyst which can be recycled.

Abstract: The invention relates to a method of producing ruthenium complexes of general formula (I): RuX2(=CH-CH2R)L L , wherein X is an anionic ligand, R is hydrogen or an optionally substituted C1-20 alkyl radical or C6-20 aryl radical, and L and L independently are neutral electron-donor ligands. Said ruthenium complexes are produced by a) reacting RuX3 with a diene in a solvent on the basis of one or several aliphatic secondary alcohols in the presence of a reducing adjuvant, reacting said mixture with L and L in the presence of at least one coordinating weak base and hydrogen and without isolating any intermediates, b) reacting the mixture with compounds of general formula (II): R-C=CH, wherein R has the meaning indicated above, in the presence of a soluble chloride source.

Abstract: The invention concerns the production of epoxides fromolefins using aromatic peroxycarboxylic acids. Followingepoxidisation (step A), the aromatic carboxylic acids therebyproduced are separated from the epoxides and catalyticallyhydrated (step B) to form the corresponding aromatic aldehydeswhich are then oxidised (step C) with oxygen or with anoxygen-containing gas mixture to form again the aromaticperoxycarboxylic acids which can be used again to produce theepoxides.9 claims
