Abstract: In the prepn. of pure aminoalkyl- or -aryl-melamine derivs. of formula (I), melamine is reacted with a diamine of formula H2N-R-NH2 (IV) in molar ratio diamine:melamine at least 10:1, esp. at least 20:1. In (I), R = linear alkylene contg. at least 2C, branched alkylene contg. at least 3C, cycloalkylene contg. at least 5C, and one or more C atoms in the alkylene or cycloalkylene gps. can be replaced by heteroatoms, or R is an aromatic gp. or a gp. having formula (II). a, b each = 0-6. A new mixt. is claimed contg. at least 75 wt.% (I) and up to 25 wt.% dimer of (I) having formula (III) obtainable by the process in (1).

Abstract: In a new process for the prodn of ketone of formula R1-C0-R2 (I) by reaction of a carboxylic acid of formula R1-C00H (IIa) with a carboxylic acid of formula (IIb) or with a ketone of formula (Ib) or of a mixture of (IIa), R2-C00H (IIb) and R2C0-R2 (Ia) in the gas phase in the presence of a catalyst, a catalyst is used in which at least 50% of the active mass consists of titanium dioxide and which has a specific surface of greater than 10 sq metres/gramme. In (I)-(IIb) R1, R2 = alkyl, cycloalkyl, arylalkyl, aryl or heteroaryl, at least one of R1 and R2 carrying at least one H-atom in the alpha-position.

Abstract: The invention relates to an advantageous method for industrial production of sought-after odoriferous musk root substances 2-cyclododecyl-propanol by reacting cyclododecene in the presence of catalytic amounts of a radical initiator with an excess of propionic acid or propionic acid derivative and subsequent catalytic hydrogenation of the formed 2-cyclododecyl propionic acid or the corresponding 2-cyclododecyl propionic acid derivatives.
