Patent number: 7241424Abstract: The present invention discloses an apparatus and method for rapid analysis of members of a combinatorial library. The apparatus includes a plurality of vessels for containing individual library members and a fluid handling system that apportions a test fluid about equally between each of the vessels. This allows for simultaneous screening of library members by detecting changes in test fluid following contact with individual library members. Fluid flow through each of the vessels is controlled using passive flow restrictors or active flow controllers to ensure that each library member contacts approximately the same amount of test fluid per unit time. The disclosed apparatus is especially useful for screening library members based on their ability to catalyze the conversion of fluid reactants.Type: GrantFiled: February 8, 2002Date of Patent: July 10, 2007Assignee: Symyx Technologies, Inc.Inventors: Shenheng Guan, Lynn Van Erden, Robert C. Haushalter, Xiao Ping Zhou, Xuejun Jason Wang, Ravi Srinivasan

Patent number: 7148390Abstract: Alcohols, ethers, aldehydes, and olefins are manufactured from alkanes by mixing an alkane and a halogen selected from the group including chlorine, bromine, and iodine in a reactor to form alkyl halide and hydrogen halide. The alkyl halide only or the alkyl halide and the hydrogen halide are directed into contact with metal oxide to form an alcohol and/or an ether, or an olefin and metal halide. The metal halide is oxidized to form original metal oxide and halogen, both of which are recycled.Type: GrantFiled: February 27, 2003Date of Patent: December 12, 2006Assignees: GRT, Inc., The Regents of the University of CaliforniaInventors: Xiao Ping Zhou, Ivan Marc Lorkovic, Jeffrey H.

Patent number: 7115231Abstract: An apparatus for use in parallel reaction of materials. The apparatus includes a base having a plurality of reaction wells formed therein and a sealing device positioned over the reaction wells for individually sealing each of the reaction wells. One of the sealing device and the base having chamfered ridges extending generally around a periphery of each of said plurality of reaction wells. The other of the sealing device and the base having a contact surface formed of a material softer than the material of the chamfered ridges to create a knife-edge seal between the sealing device and the base when the sealing device and the base are forced into contact with one another.Type: GrantFiled: October 17, 2000Date of Patent: October 3, 2006Assignee: Symyx Technologies, Inc.Inventors: Xiao Ping Zhou, Sam Bergh, Christopher E.

Patent number: 6933409Abstract: Noble metal/reducible metal oxide catalysts effective for the direct amination of aromatic hydrocarbons and heterocyclic analogs thereof are disclosed. In one embodiment, the cataloxidant comprises a noble metal selected from Pd, Rh, Ir and/or Ru and a reducible metal oxide. In another embodiment, the cataloxidant comprises a noble metal and a reducible oxide of a metal selected from Ni, Mn, V, Ce, Th, Pr, Te, Re, Co, Fe, Cu and/or Bi. A preferred cataloxidant comprises one or more noble metals selected from Pd, Rh, Ir and/or Ru, in combination with nickel oxide and/or manganese oxide. In preferred applications, benzene can be aminated in the presence of the cataloxidants to form aniline. A benzene conversion of at least 5% is achieved, with more than 90% selectivity for aniline. Significantly, the cataloxidant can be regenerated without a substantial loss of performance.Type: GrantFiled: May 15, 2000Date of Patent: August 23, 2005Assignees: Symyx Technologies, Inc., Bayer AGInventors: Damodara M.

Patent number: 6667009Abstract: Methods and devices for rapidly analyzing groups of reactions are disclosed. The method includes the steps of contacting a fluid sample from one of the reaction mixtures with a sorbent, trapping at least one component of the fluid sample on the sorbent, and detecting the at least one component of the fluid sample trapped on the sorbent. The contacting step, the trapping step, and the detecting step are carried out at least once for each of the reaction mixtures in rapid serial or parallel fashion. The present invention is useful for screening combinatorial libraries, especially libraries of catalysts made through parallel synthesis, but the disclosed methods and devices can be used to analyze a broad spectrum of chemical transformations.Type: GrantFiled: April 20, 2000Date of Patent: December 23, 2003Assignee: Symyx Technologies, Inc.Inventors: Peter J.
