标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

标 题:Synthesis of zeolite ZSM-5
发明人：PELRINE BRUCE PATRICK
权利人:MOBIL OIL CORP
摘要:As synthesized by conventional technique, zeolite ZSM-5 crystals are cubic with some twinning and measure in size over the range of from about 3 × 3 microns to about 8 × 8 microns. By synthesizing crystalline aluminosilicate zeolite ZSM-5 according to the present method, i.e. in the presence of a tetraureacobalt (II) complex and with a specifically defined reaction mixture composition, the crystalline product will consist of highly twinned rectangular prismatic crystals exhibiting extreme uniformity in size of from about 5 × 10 microns to about 10 × 20 microns, depending on the ratio of said tetraureacobalt (II) complex to silica in the zeolite synthesis reaction mixture. Synthesis of ZSM-5 in accordance hereto will provide a zeolite with enhanced catalytic activity for certain chemical reactions.

标 题 :Electrochemical process for the synthesis of organic compounds
发明人：OBERRAUCH ERMANNO; EBERSON LENNARD
权利人:ANIC SPA
摘要:An electrochemical process is disclosed for the synthesis of organic compounds, said process having the unique characteristic that the element evolved at the anode is exploited by having it reacting with the product of electrolysis obtained at the cathode by the presence of an appropriate catalyst. The catalyst may be associated in the most convenient manner to the anode, or it can be the anode itself. The process opens the way to a number of synthesis reaction which may be carried out electrolytically instead of the conventional ways.
