Abstract
The method for producing a vapor composition containing lactic acid of the present invention is capable of suppressing the generation of by-products such as acetaldehyde and carbon monoxide due to pyrolysis of a lactic acid species during vaporization. Furthermore, a lactic acid oligomer generated can be effectively used without loss, and a vapor composition containing lactic acid can be industrially efficiently produced stably for a long time. The present invention relates to a method for producing a vapor composition containing lactic acid including: feeding a liquid composition containing lactic acid to a vaporizer; mixing the liquid composition with a liquid composition containing a lactic acid oligomer contained in the vaporizer to prepare a liquid mixture; and heating the liquid mixture to vaporize part of the liquid mixture, whereby a vapor composition containing lactic acid is produced.
