Method for producing polyoxyalkylene alkyl ether carboxylic acid and salt thereof |
| abstract |
The present invention provides a method for producing polyoxyalkylene alkyl ether carboxylic acid and a salt thereof, including supplying polyoxyalkylene alkyl ether, oxygen, and water to a continuous stirred tank reactor containing a noble metal catalyst to oxidize the polyoxyalkylene alkyl ether with oxygen, in which the molar ratio of the salt of polyoxyalkylene alkyl ether carboxylic acid to the polyoxyalkylene alkyl ether in the continuous stirred tank reactor is controlled to 0.33 to 49. |
