实验性质
| 外观 / 形态 : | COLOURLESS OILY LIQUID.；Colorless, oily liquid with a slight, aromatic odor.；Colorless, oily liquid with a slight, aromatic odor. [Note: A solid below 42 °F.]；Colorless, oily liquid with a slight, aromatic odor; Note: A solid below 42 degrees F; [NIOSH]；Dimethyl phthalate appears as 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 contact may produce mild irritation. Used in the manufacture of a variety of products including plastics, insect repellents, safety glass, and lacquer coatings.；Liquid; CBI; Other Solid |
