  • Production of alkyl 6-aminocaproate
    Patent number: 6365770
    Abstract: A process for making alkyl 6-aminocaproate by hydroformylating 3-pentenenitrile to produce 3-, 4-, and 5-formylvaleronitrile (FVN mixture), converting the FVN mixture to alkyl 3-, 4-, and 5-cyanovalerate by either oxidative esterification of the FVN mixture or oxidation of the FVN mixture followed by esterification; isolating alkyl 5-cyanovalerate; and hydrogenating the alkyl 5-cyanovalerate to produce alkyl 6-aminocaproate. The resulting alkyl 6-aminocaproate can be cyclized to produce caprolactam.

  • Heat exchanger with tube plates
    Patent number: 6364008
    Abstract: A heat exchanger comprising plates of thermoplastic tubes arranged in a way which minimizes the thermal resistance at the outer surface of the tubes preferably to not more than 5 times the resistance to heat transfer at the inside of the tubes. The tubes are arranged in the tube plates in groups that can be flat or slightly wavy, such as undulating in a periodic manner, or offset with open spaces facing groups of tubes in alternating rows. This is done in a way that maximizes turbulence outside the tubes and minimizes vortices which can trap coolant in the interstices between tubes.

  • Genes and enzymes for the production of adipic acid intermediates
    Patent number: 6365376
    Abstract: Two gene clusters have been isolated from an Brevibacterium sp HCU that encode the enzymes expected to convert cyclohexanol to adipic acid. Individual open reading frames (ORF's) on each gene cluster are useful for the production of intermediates in the adipic acid biosynthetic pathway or of related molecules. All the ORF's have been sequenced. Identification of gene function has been made on the basis of sequence comparison and biochemical analysis.

  • Modular communications socket
    Patent number: 6364694
    Abstract: A socket has a body, an enlarged pin, a detecting pin and multiple contact pins. The enlarged pin and the detecting pin are separately secured in the body. The contact pins are secured in the cavity of the body in a row between the enlarged pin and the detecting pin. The enlarged pin is longer than each contact pin so that an enlarged section is formed on the enlarged pin. A lateral rod is formed on the detecting pin and extends to a position below the enlarge section of the enlarged pin. Consequently, the socket can automatically indicate whether a plug inserted into the socket is a cable plug or a telephone plug. The socket can be used with different types of modular communications plugs. The cost for manufacturing the computer or a modem that can accommodate different transmission media is reduced.

  • Process for the preparation of &agr;-methylene-&ggr;-butyrolactone and &agr;-acetoxymethyl-&ggr;-butyrolactone
    Patent number: 6362346
    Abstract: This invention pertains to a process for making &agr;-methylene-&ggr;-butyrolactone by acid-catalyzed rearrangement of tetrahydro-3-furoic acid. In a further embodiment, when tetrahydro-3-furoic acid is treated with acetic anhydride and an acid catalyst, &agr;-acetoxymethyl-&ggr;-butyrolactone is produced in high yield. Under basic conditions, &agr;-acetoxymethyl-&ggr;-butyrolactone can readily form&agr;-methylene-&ggr;-butyrolactone by the elimination of acetic acid. These reactions provide &agr;-methylene-&ggr;-butyrolactone by novel routes which do not require butyrolactone or formaldehyde.
