  • Method for the production of aminoalkane acid amides
    Patent number: 8759580
    Abstract: The invention relates to a process for preparing aminoalkanamides by reacting cyanoalkanoic esters with a) ammonia or an amine and b) hydrogen in the presence of a catalyst, the reaction with component b) being started simultaneously or not later than a maximum of 100 minutes after commencement of the reaction of the cyanoalkanoic ester with component a).
    Type: Grant

  • Method of producing N-substituted 2,6-dialkylmorpholines
    Patent number: 7105662
    Abstract: The present invention relates to a process for the preparation of N-substituted 2,6-dialkylmorpholines of the formula I in which R1 and R2, independently of one another, are hydrogen, alkyl or cycloalkyl, or R1 and R2 together with the carbon atom to which they are bonded are a 5- to 14-membered carbocycle, and R3 and R4, independently of one another, are alkyl or cycloalkyl, by reacting at least one carbonyl compound of the formula II in which R1 and R2 have the meanings given above, with at least one morpholine of the formula III in which R3 and R4 have the meanings given above, in the presence of hydrogen and at least one metal-containing catalyst, wherein the active component of the catalyst consists essentially of platinum group metals.

  • Method for producing unsaturated cyclic ethers
    Publication number: 20040092753
    Abstract: A method for producing unsaturated cyclic ethers of general formula (I) wherein Z represents (CHR4)q— or (CHR4)q—O—, q 0, 1, 2 or 3 and R1, R2, R3, R4 represent hydrogen or C1-C4-alkyl, by reacting dioles of general formula (II), wherein Z, R1, R2 and R3 have the above-mentioned meanings, in a liquid phase at temperatures of 150-300° C. in the presence of a support catalyst which is not activated prior to use by reduction and which contains cobalt and is doped with sulphur, containing cobalt, and an earth metal which is deposited by sol impregnation and is selected from the group containing platinum, palladium, rhodium, iridium, ruthenium, osmium, rhenium or mixtures thereof, on an inert support, characterized in that water is added.
