4,6-Dimethyldibenzothiophene is an organosulfur compound with the formula (C 6 H 3 CH 3) 2 S.It is one of several dimethyl derivatives of benzothiophene.The compound is of particular interest as an organosulfur contaminant in petroleum that is recalcitrant.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
