标题 :Use of a heterogeneous copper/zinc catalyst for continuous, gas-phase synthesis of methyl isobutyl ketone and/or methyl isobutyl carbinol by hydrogenation of mesityl oxide
发明人：RUPPIN CHRISTOPHE
权利人:ARKEMA FRANCE
摘要:The present invention relates to the use of a catalyst comprising a mixture of copper and zinc for continuous, gas-phase synthesis of methyl isobutyl ketone (MIBK) and/or methyl isobutyl carbinol (MIBC) from mesityl oxide. The invention also relates to a synthesis method comprising the following sequence of steps: continuous injection of the reagents in gas form through a reactor; hydrogenation reaction under pressure of hydrogen and at a temperature of between 120 and 250°C in the presence of the catalyst; condensation of the stream from the reactor and separation of the gas stream from the liquid stream; and purification of the liquid stream in order to separate the methyl isobutyl ketone and/or the methyl isobutyl carbinol.

标题:Electrochemical deblocking solution for electrochemical oligomer synthesis on an electrode array
发明人：MAURER KARL; COOPER JOHN J
权利人:CUSTOMARRAY INC
摘要:There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.
