  • Patent number: 6454818
    Abstract: The present invention is one kind of gasoline additives. The compounds consist of tertiary amine, amide and poly(oxybutylene) backbone in the same molecule. The process of making this type of products required an initiator containing primary amine and tertiary amine as the starting diamines. The primary amine will be converted into amide, while the tertiary amine remained intact. Then the amide is converted into butoxylates through butoxylation at CON—H position. The preparation therefore involved two steps: (1) amidation of diamines containing primary/tertiary amines with ethyl acetate to form amidoamines, and (2) butoxylation of this amidoamines to poly(oxybutylene)amidoamine. The product is gasoline soluble and can be used as additive having good performance of detergency and octane requirement reduction.

  • Patent number: 6384278
    Abstract: The present invention provides an inexpensive one-step method for preparing an aromatic carboxamide, such as a phenyl substituted carboxamide) by reacting an aromatic amine (e.g. a phenylamine) and a carboxylic acid (e.g. an alkanoic acid or ester thereof) in the presence of a boron containing compound (e.g. boronic acid or boric acid) and, optionally, a chelating agent (e.g. a 2-pyridinylamine).

  • 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: 6291712
    Abstract: A process for producing a saturated aliphatic carboxylic acid amide, comprising reacting a saturated aliphatic carboxylic acid with ammonia to thereby obtain a saturated aliphatic ammonium carboxylate and subjecting the saturated aliphatic ammonium carboxylate to a dehydration reaction for obtaining a saturated aliphatic carboxylic acid amide, wherein the dehydration reaction of the saturated aliphatic ammonium carboxylate is conducted while supplying water to a reaction system in which the dehydration reaction is carried out. Preferably, water is continuously supplied to the reaction system so that the production of the saturated aliphatic carboxylic acid amide is carried out in a continuous manner and the amount of water present in a steady state ranges from 20 to 70 mol per 100 mol of a total of the saturated aliphatic carboxylic acid, the ammonia, the saturated aliphatic ammonium carboxylate, the saturated aliphatic carboxylic acid amide and the water.

  • Patent number: 5861532
    Abstract: Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.
