Abstract

1507320 Manufacture of dimethylaminobenzenes BASF AG 8 Aug 1975 [10 Aug 1974 16 Nov 1974] 33141/75 Addition to 1462258 Heading C2C The invention comprises a process for the manufacture of compounds of Formula I wherein individual radicals R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP> are independently halogen, optionally substituted aliphatic or aromatic hydrocarbon radical -SO 3 R<SP>4</SP>, SO 2 N(R<SP>4</SP>) 2 , SO 2 R<SP>4</SP>, SO 2 NHCOR<SP>4</SP>, OR<SP>4</SP>, COR<SP>4</SP>, NHCOR<SP>4</SP> wherein R<SP>4</SP> is an optionally substituted aliphatic hydrocarbon radical, and the individual radicals R<SP>2</SP> and R<SP>3</SP> may also be independently hydrogen, phenoxy or -CO 2 R<SP>5</SP>, R<SP>5</SP> being an optionally substituted aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical, and adjacent radicals R<SP>3</SP> or R<SP>1</SP> and an adjacent radical R<SP>3</SP> may also, together with the two carbon atoms linking them, form a fused heterocyclic radical, wherein a nitrobenzene of Formula II in which R<SP>1</SP>, R<SP>2</SP>, and R<SP>3</SP> are as defined above is reacted with formaldehyde and hydrogen in the presence of a hydrogenation catalyst containing one or more metals of atomic number 24 to 29 and of a weak organic acid at 35‹ to 150‹ C. and a pressure of at least 40 atmospheres.
