Title:
METHOD FOR PRODUCING ALIPHATIC DICARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP2011219409
Kind Code:
A
Abstract:
To provide a method for efficiently and stably producing an aliphatic dicarboxylic acid in a high purification degree by removing various materials originated from a biomass resource in high efficiency from an aqueous solution containing at least one selected from the aliphatic dicarboxylic acid and an aliphatic dicarboxylic acid salt obtained from the biomass resource.
The method for producing the aliphatic dicarboxylic acid includes a step for bringing the aqueous solution containing at least one selected from the aliphatic dicarboxylic acid and the aliphatic dicarboxylic acid salt derived from the biomass resource into contact with an activated carbon having a specific surface area of ≥1,300 m2/g and ≤5,000 m2/g.
