Abstract: A process for the chlorination, using gaseous chlorine, of phenolic compounds substituted in an ortho position relative to the hydroxyl function group. More precisely, it is a process for the chlorination of these phenolic compounds in the molten state or in a solvent medium, using gaseous chlorine, in the presence of an organic cation. The process is applicable especially to the chlorination of 2,6- dichlorophenol to 2,4,6-trichlorophenol.

Abstract: Chlorination of ortho-chlorophenol to 2,6-dichlorophenol, performed in the melt optionally in the presence of other chlorophenols and in the presence of an effective quantity of a primary, secondary or tertiary amine. 2,6-Dichlorophenol can be used especially as intermediate for the preparation of plant-protection products.

Abstract: The chlorophenols, e.g., 2,4,6-trichlorophenol, are efficiently prepared by chlorinating an ortho-/para-substituted phenolic compound with gaseous chlorine, whether in molten state or in a solvent reaction medium, in the presence of a catalytically effective amount of a primary, secondary or tertiary amine.

Abstract: Novel dinuclear and water-soluble rhodium complexes, well suited as hydroformylation catalysts, as are aqueous solutions thereof, have the general formula: (I) in which R and R', which are identical or different, are each a substituted or unsubstituted hydrocarbon radical, with the proviso that R and R' may together form a single divalent radical, TAPS is a sulfonated triarylphosphine ligand, and L is a carbonyl (CO) or a TAPS ligand.

Abstract: BREVET D'INVENTION PROCEDE DE CHLORATION DE L'ORTHOCHLOROPHENOL Société dite : RHONE-POULENC CHIMIE Inventeurs : Jean-Claude LEBLANC Serge RATTON Bernard BESSON Jean DESMURS DU CONTENU TECHNIQUE DE L'INVENTION La presente invention concerne la chloration de l'orthochlorophénol en dichloro-2.5 phénol. Cette chloration s'effectue à l'état fondu éventuellement en présence d'autres chorophénols et en présence d'une quantité efficace d'une amine primaire, secondaire ou tertiaire. Le dichloro-2,6 phenol peut servir notamment d'intermediaire pour la préparation de produits phytosanitaires.
