  • Patent number: 10099985
    Abstract: This invention provides producing having an objective ketone and/or alcohol by decomposing of a hydrocarbon compound rapidly and selectively having a same number of carbon atoms as a hydrocarbon compound by decomposing a hydroperoxide in a reaction solution obtained from oxidizing the hydrocarbon compound using molecular oxygen of this invention involves, a hydroperoxide decomposition step for decomposing the hydroperoxide into the ketone and/or alcohol by contacting the reaction solution with an aqueous solution containing a carbonate of an alkaline earth metal or a carbonate of an alkali metal and a transition metal compound, a separation step for separating into an oil phase comprising the ketone and/or alcohol, and a water phase comprising the carbonate of an alkaline earth metal or carbonate of an alkali metal and the transition metal compound, a recovery step for recovering the carbonate of an alkali metal or carbonate of an alkaline earth metal and the transition metal compound by combusting the water

  • Publication number: 20130184494
    Abstract: According to the first embodiment of the present invention, an oxide of a hydrocarbon compound can be produced with high yield and high productivity by oxidizing the hydrocarbon compound with molecular oxygen in the co-presence of an N-hydroxy compound, such as methyl ethyl ketone or N-hydroxysuccinimide, and a phosphate ester, such as dibutyl phosphate. According to another embodiment of the present invention, an oxide of a hydrocarbon compound can be produced with high yield by using an oxidation catalyst that comprises an oxime compound, such as methyl ethyl ketone. According to another embodiment of the present invention, an alcohol and/or a ketone can be produced with high yield by oxidizing the hydrocarbon compound at a temperature of 160° C. or less, and by decomposing the resulting hydroperoxide, for example, in a unit having an inner surface formed by a material from which no transition metal ion is generated.

  • Patent number: 6348626
    Abstract: Oxamide is produced in a high purity by a process comprising (A) melting a starting material comprising 70 to 100 wt % of an oxalic acid diester of an aliphatic alcohol and 0 to 30 wt % of the same aliphatic alcohol as mentioned above, (B) feed-mixing an ammonia-containing gas to the starting material melt, while stirring, to produce oxamide and the aliphatic alcohol (by-product), (C) continuing the ammonia-feed-mixing procedure while controlling a feed rate of ammonia to an extent such that a content of the aliphatic alcohol in the reaction mixture is maintained at a level of 3 to 45% by weight, to produce a wetted solid reaction product comprising the resultant oxamide and the aliphatic alcohol, and then (D) collecting the oxamide from the reaction product by evaporating away the aliphatic alcohol.

  • Patent number: 5393319
    Abstract: Oxamide granules are produced by (A) feed-mixing ammonia to a starting material comprising 60 to 100 weight % of a diester of oxalic acid with a C.sub.1-6 aliphatic alcohol, and 0 to 40 weight % of the same aliphatic alcohol as mentioned above, to produce oxamide and the aliphatic alcohol as by-product, while controlling the aliphatic alcohol content to 5 to 40% based on the weight of the reaction mixture to provide the resultant oxamide wetted by the aliphatic alcohol; (B) granulating the wetted product while maintaining the content of the aliphatic alcohol at a level of 5 to 40% based on the weight of the wetted reaction product; (C) heat-evaporating away the aliphatic alcohol from the wetted granules; and optionally (D) re-wetting the resultant dry oxamide granules with water in an amount of 5 to 20% based on the weight of the dry oxamide granules; and (E) re-drying the re-wetted oxamide granules, to provide oxamide granules having an enhanced mechanical strength and form-stability in water.
