Methyl ethyl ketone - Sciencemadness Wiki

Methyl ethyl ketone is a clear, colorless fluid that is less viscous than water and has a somewhat sharp, sweet odor characteristic of most ketones, with some describing it as similar to butterscotch. Compared to acetone it is much less volatile and is less soluble in water (approximately 27.5 g/100 ml at room temperature).
