Sublimation in gradient-temperature tube-furnace offers a new possibility for separating analogus compounds which the standard sublimation method failed to separate. The behaviors of 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol, pentachlorophenol, naphtalene, 1,4-naphthoquinone, anthracene, chrysene, copper acetylacetonate, chromium acetyla-cetonatecomplex, alumiumacetylacacetonatecomplex, mercurous chloride and mercurous bromide, when sublimed in it, have been investigated. 1) Chemical pure 2,4,6-trichlorophenol was sublimed into three parts, 2,3,4,6-tetachlorophenol was sublimed into two parts but pentachlorophenol was sublimed into only one part. 2) Naphtalene was sublimed over at about 45℃ in high vacum and 1,4-naphtoquinone was sublimed at about 70℃ Naphtalene was completely separated from 1,4-naphtoquinone. 3) Chemical pure anthracene was sublimed into three parts and also chrysene was sublimed into three parts. 4) Copper acetylacetonate was sublimed at about 130℃ chromium acetylacetonate was sublimed at about 140℃ and alumium acetylacetonate was sublimed at about 115℃. 5) Mercurous chloride was sublimed at about 170℃. Mercurous bromide was sublimed at about 170℃.
