Abstract: IN A PROCESS FOR THE HYDROFORMYLATION OF ETHYLENICALLY UNSATURATED COMPOUNDS, AT LEAST ONE COMPLEX OF A METAL OF TRANSITION GROUP VIII. WITH AT LEAST ONE PHOSPHORUS-, ARSENIC-OR ANTIMONY-CONTAINING COMPOUND AS LIGAND IS USED AS HYDROFORMYLATION CATALYST, WHERE THE COMPOUND USED AS LIGAND IN EACH CASE COMPRISES TWO GROUPS WHICH COMPRISE A P, AS OR SB ATOM AND AT LEAST TWO FURTHER HETERO ATOMS AND ARE BOUND TO A XANTHENE-LIKE MOLECULAR FRAMEWORK. NEW COMPOUNDS OF THIS TYPE AND CATALYSTS WHICH COMPRISE AT LEAST ONE COMPLEX OF A METAL OF TRANSITION GROUP VIII. WITH AT LEAST ONE SUCH COMPOUND AS LIGAND ARE ALSO PROVIDED.

Abstract: THE INVENTION RELATES TO PROCESSES FOR THE PREPARATION OF ALKYLARYLSULFONATES BY A) REACTION OF A C4-OLEFIN MIXTURE OVER A METATHESIS CATALYST TO PREPARE AN OLEFIN MIXTURE COMPRISING 2-PENTENE AND/OR 3-HEXENE AND OPTIONAL REMOVAL OF 2-PENTENE AND/OR 3-HEXENE,B) DIMERIZATION OF THE 2-PENTENE AND/OR 3-HEXENE OBTAINED IN STAGE A) IN THE PRESENCE OF A DIMERIZATION CATALYST TO GIVE A MIXTURE COMPRISING C10-12-OLEFINS AND OPTIONAL REMOVAL OF THE C10-12-OLEFINS, C) REACTION OF THE C10-12 MIXTURES OBTAINED IN STAGE B) WITH AN AROMATIC HYDROCARBON IN THE PRESENCE OF AN ALKYLATION CATALYST TO FORM ALKYL AROMATIC COMPOUNDS, WHERE, PRIOR TO THE REACTION, ADDITIONAL LINEAR OLEFINS MAY BE ADDED,D) SULFONATION OF THE ALKYL AROMATIC COMPOUNDS OBTAINED IN STAGE C) AND NEUTRALIZATION TO GIVE ALKYLARYLSULFONATES, WHERE, PRIOR TO THE SULFONATION, LINEAR ALKYLBENZENES MAY ADDITIONALLY BE ADDED,E) OPTIONAL MIXING OF THE ALKYLARYLSULFONATES OBTAINED IN STAGE D) WITH LINEAR ALKYLARYLSULFONATES.
