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.

标 题:Cryogenic process for removing acid gases from gas mixtures by means of a solvent
发明人：GAZZI LUIGI; D AMBRA ROBERTO; DI CINTIO ROBERTO; RESCALLI CARLO; VETERE ALESSANDRO
权利人:SNAM PROGETTI
摘要:A process for removing acid gases from natural or synthesis gases by absorption, comprising the following stages: n (a) cooling the natural or synthesis gas to be purified to condense part of the CO 2 contained in said gas; n (b) feeding the cooled and partly condensed gas to an absorption column in order to reduce the acid gas content to the required value; n (c) regenerating the solvent or solvents used in the acid gas absorption, the solvent or solvents used being chosen from esters, alcohols and ethers of low molecular weight.
