| titleOfInvention | Production method of alkyl oxalate |
| abstract | PROBLEM TO BE SOLVED: To provide an alkyl oxalate by reacting CO and RONO, and to produce RON from by-produced nitric oxide. In a method for producing an alkyl oxalate while regenerating and reusing O, the heat of reaction in the regeneration of RONO can be effectively removed to maintain the reaction temperature in an appropriate range, An object of the present invention is to provide an industrial process for producing an alkyl oxalate, which can avoid various problems of known processes. The object of the present invention is to provide CO and RON in one step. O is reacted to produce alkyl oxalate, the reaction gas is brought into contact with the absorbing solution in two steps to extract a condensate in which the alkyl oxalate is condensed and dissolved, and a non-condensed gas is taken out in three steps. The condensed gas is supplied to the regeneration tower, and the nitric oxide and the alcohol are reacted to generate RONO. A method for obtaining an alkyl oxalate by distilling and purifying the condensate in four steps, wherein in three steps the circulation amount of the regeneration tower can solution, the total alcohol supply amount and the molar ratio of nitric oxide, and the Is solved by a method for producing an alkyl oxalate in which RONO is produced while maintaining the alcohol concentration in a specific range and reused in one step. |
