2,6-Dimethylnaphthalene → 2,7-Dimethylnaphthalene

참여 물질

반응 단계

An agitation vessel of the same type as used in the crystallizing steps of Example 1 was charged with 152.2 g of a solution consisting of 2,6-DMN, 2,7-DMN and paraxylene at a weight ratio of 9:9:82 and the charged solution was cooled from 19.5° C. to 7.0° C. over a period of 72 minutes. The change in the composition of the liquid phase in the solution with time was analyzed and it was found that 2,6 -DMN and 2,7-DMN formed a eutectic mixture at a 2,6-DMN/2,7-DMN ratio of 0.59.
