  • Patent number: 5004568
    Abstract: A method is disclosed for the production of esters by reaction of an allylic ether with carbon monoxide in the presence of a catalytically effective amount of a Group VIII noble metal catalyst and a Group IB metal halide to obtain esters. The Group IB metal halide is present in an amount sufficient to prevent the catalyst from being converted into a Group VIII metal during the reaction. When the reaction is conducted in the presence of a quaternary ammonium salt the ester may be extracted by solvent extraction to minimize catalyst decomposition caused when extractive distillation is used to separate the ester.

  • Patent number: 5001060
    Abstract: DNA sequence elements which effect anaerobic induction of genes in plants are identified and characterized. These sequence elements, designated anaerobic regulatory elements, confer inducibility by anaerobic conditions on downstress plant-expressible promoters and their associated structural genes. In particular, those sequences associated with anaerobic induction of the maize alcohol dehydrogenase and aldolase genes have been identified. These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to produce chimeric, anaerobically inducible genes. Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

  • Patent number: 5001263
    Abstract: This invention relates to a process for producing ring alkylated aromatic amines where the alkyl substituent is ortho to the amino group by reacting an N-alkylated aromatic amine with a C.sub.2-10 olefin in the presence of a solid phase acidic catalyst, e.g., silica-alumina or a zeolite. High conversion and selectivity is achieved by maintaining a mole ratio of olefin to amine of from about 1-10:1 and an operating pressure of at least 50 psig.
