  • Patent number: 5387402
    Abstract: To effect a quasi-isothermal catalytic reaction of SO.sub.2 to SO.sub.3, a plurality of consecutive rows of banks of cooling tubes, are provided in the bed of shaped catalyst bodies in a contact reactor in such a manner that the banks of succeeding rows are staggered from the banks of the preceding rows. The distance between the cooling tubes in the banks is so selected that a penetration of entire catalyst bodies into the banks will virtually be prevented. The banks are so designed that the pressure drop of the gas in the banks is approximately the same as the pressure drop in the layer of catalyst between the bank. The distance between the banks is larger than the width of the banks.

  • Patent number: 5387704
    Abstract: Process for preparing amino- and carbamoyl-substituted anthraquinones by Diels-Alder reaction of an N-butadienylcarbamic acid ester of the formula H.sub.2 C.dbd.CH--CH.dbd.CH--NH--COOR.sup.2, wherein R.sup.2 is alkyl or phenylalkyl, with a 1,4-naphthoquinone or with 1,4-benzoquinone to form a carbamoyl-substituted hydroanthraquinone intermediate and by oxidation of this intermediate with an oxygen-containing gas in a tertiary amine and in the presence of a copper salt to obtain a carbamoyl-substituted anthraquinone product. The Diels-Alder reaction and the oxidation reaction can be carried out as a one-pot synthesis or in separate steps. The carbamic acid ester reactant provides a blocking group represented by --COOR.sup.2, and this blocking group is optionally removed by treatment of the carbamoyl-substituted anthraquinone with an alkaline hydroxide solution.
