Questions

  1. Why 4-heptanone is insoluble?

    1 answer

    1. The solubility of this material is not tested internally. While literature indicates that it is minimally soluble in water (around 4.6 g/L at 20°C), it should be more soluble in ethanol, methanol, diethyl ether, heptane, hexane, and carbon tetrachloride. Optimal concentration will need to be determined by the end user.
