Naphthalene from the Kukker shale of the Finnish coast

Abstract

The initial material was oil shale collected during exploration work by N.F. Pogrebov. After distillation of the illuminating gas, tar remains, which served as the material for this study. When this material is distilled in a water bath, crystalline, very thin plates of distilled organic matter with inclusions of another substance with much greater refraction and apparently capable of very good crystallization settle in the tube. This distillation was carried out by Mr. Valchis.
