A method for recovering crystalline 2-6-dimethylnaphthalene comprising crystallizing in a scraped-wall crystallizer apparatus at crystallization temperature T, a mixture of low melting components (LM), having melting points of 70 DEG F and below, and high melting components (HM), including 2,6-dimethylnaphthalene, having melting points above 70 DEG F, such that: HM/LM < 0.03(T-50) + A, where HM is the total weight percent of high melting components, including 2,6-dimethylnaphthalene, in the mixture, an LM is the total weight percent of low melting components in the mixture, and where T is the temperature of the crystallization in degrees Fahrenheit, and where A is at least 1.0.
