Description

Colorless oily liquid with a slightly aromatic fragrance. Immiscibility with ethanol, ethyl ether , soluble in organic solvents such as benzene, acetone, insoluble in water and mineral oil. colourless oily liquid Dimethyl phthalate occurs as a colorless, or faintly colored, odorless, viscous, oily liquid.A water-white liquid without significant odor. Denser than water and insoluble in water. Hence sinks in water. Flash point 300°F. Eye contact may produce severe irritation and direct skin c
