摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

标 题:Preparation of 2,2'-oxydisuccinate
发明人：SCHULTZ ROBERT G
权利人:MONSANTO CO
摘要:There is disclosed herein an improved processes for the preparation of oxydisuccinate by reacting in an alkaline reaction medium the salts of maleic acid and malic acid in the presence of a calcium ion catalyst wherein unreacted maleic acid salts are recovered from the reaction medium as sodium hydrogen maleate by lowering the pH of the reaction product to a range of from about 4 to 6. The precipitated sodium hydrogen maleate salts are recycled to the synthesis reaction as salts of malic acid by hydration in the presence of a hydration catalyst to prepare additional amounts of product.

摘要:There is disclosed herein improved processes for the preparation of ether carboxylates by reacting in an alkaline reaction medium the salts of maleic acid and a carboxylic or polycarboxylic acid having a reactive hydroxyl group on a non-carbonyl carbon atom in the presence of a calcium ion catalyst wherein unreacted acid salts are recovered from the reaction medium by lowering the pH of the reaction medium to a range of from about 4 to about 6. The precipitated salts are recycled to the synthesis reaction to prepare additional amounts of product.

摘要:There is disclosed herein improved processes for the preparation of ether carboxylates by reacting in an alkaline reaction medium the salts of maleic acid and malic acid in the presence of a calcium ion catalyst wherein unreacted acid salts are recovered from the reaction medium by lowering the pH of the reaction medium to a range of from about 4 to about 6 in two steps, the first step ending at a pH in the range of from about 7 to about 8.5. The precipitate is removed and the pH of the reaction medium is then lowered further to a pH in the range of from 4 to 6. The precipitated salts are recycled to the synthesis reaction to prepared additional amounts of product.
