| titleOfInvention | Seperation of methyl pyrazine from water |
| abstract | The present invention relates to a method for separating methylpyrazine in an aqueous solution. More specifically, caustic soda is separated to recover methylpyrazine from an aqueous phase reaction product obtained by dehydration and dehydrogenation of 1,2-propylene glycol and ethylenediamine. Instead of applying the salt separation method used as a salt separation agent, the present invention relates to a method for separating methylpyrazine more efficiently by introducing an azeotropic system using an optimal azeotropic additive for increasing the separation efficiency of methyl pyrazine and water. |
