  • Patent number: 4487972
    Abstract: This specification discloses a process for the production of oxygenated compounds, more specifically aldehydes and alcohols, by reacting an olefin with hydrogen and carbon monoxide in the presence of, as a ctalyst, an insoluble polymer containing a functional group, which may be an amine, thiol, phosphine, or arsine group, having chemically bonded thereto a metal of Group VIII of the Periodic Table. The metal can be, for example, rhodium, cobalt, or ruthenium. The olefin can contain more than one carbon-to-carbon double bond, may be an open chain or a cyclic olefin, and may be substituted. Further, the olefin may be contained in a refinery stream such as a cracked gasoline. The reaction may be carried out in the presence of a polar solvent.

  • Patent number: 4486607
    Abstract: The invention relates to a process for the production of 3 (alkyl phenyl) propanals; certain of which are known to be valuable in the perfumery industry. The process enables this group of chemicals to be produced more easily as compared to known processes for their production. In a preferred embodiment in one step of the process the alkylation of the 3 phenyl propanol is carried out under controlled conditions so as to favor the production of para isomer of the product.

  • Patent number: 4484007
    Abstract: There is provided an improved process for producing biologically active arylterpenoid compounds useful to inhibit eclosion of pupae, e.g., fly pupae or mosquito pupae. The process is characterized by reacting a terpenoid material having a terminal unsaturated linkage, e.g., dihydromyrcene (3,7-dimethylocta-1,6-diene) with a lower alkyl Grignard reagent, e.g., n-propyl magnesium chloride to form a Grignard exchange product. The exchange product is then benzylated. Either a benzyl halide, e.g., p-isopropylbenzyl chloride, or a benzaldehyde, e.g., p-isopropylbenzaldehyde may be used. These compounds are specifically described in U.S. Pat. No. 4,002,769. They contain also a lower alkoxy group, e.g., methoxy. This can be introduced prior to the formation of the Grignard exchange product or at a later stage in the operation. Use of the exchange-type Grignard reaction enables elimination of several steps when producing the arylterpenoids from pinene as the terpene source, and consequent costs.

  • Patent number: 4474993
    Abstract: The disclosure relates to a continuous method and an apparatus for the hydrolysis of .alpha.-chlorinated toluene compounds, preferably benzyl chloride. The hydrolysis, which takes place in a hydrolysis zone, is characterized by being conducted in countercurrent between the aqueous phase containing the hydrolyzing agent and the organic phase containing the .alpha.-chlorinated toluene compound and an inert organic solvent, such as toluene. After the hydrolysis, the organic phase is washed with water in a washing zone, while the aqueous phase is extracted with inert solvent in an extraction zone. The resulting product of hydrolysis, preferably benzyl alcohol, is thereafter separated from the organic phase by distillation, suitably in two stages, by means of two distillation columns connected in series.

  • Patent number: 4088823
    Abstract: A process is provided for oxygenating alkyl-substituted aromatic compounds. In the process alkyl-substituted aromatic compounds are contacted with molecular oxygen in the presence of a suitable monocarboxylic acid, a soluble copper, cobalt, or iron compound, and an inorganic bromine compound. Optionally present are inorganic nitrates, acetic anhydride, or water. In an embodiment of the invention the process is carried out in two distinct steps with contact of the alkyl-substituted aromatic compounds and oxygen in the presence of the essential components produce an ester comprising both an aromatic alcohol and the carboxylic acid with subsequent hydrolyzing of this ester to produce an aromatic alcohol with regeneration of the carboxylic acid.
