Abstract: The present invention relates to a method for producing a mixture containing fatty acid monoglyceride from glycerin and a compound having at least one acyl group, selected from fatty acids and fatty acid glycerides, including: (i) a step of obtaining a mixture containing fatty acid monoglyceride by heating and reacting glycerin and a compound having at least one acyl group, selected from fatty acids and fatty acid glycerides in the presence of a catalyst; (ii) a step including adding glycerin, which is liquid and has a lower temperature than the temperature of the mixture, to the mixture to cool the mixture; and (iii) a step of separating the mixture containing fatty acid monoglyceride from glycerin, obtained in the step (ii), by separating layers.

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.
