Appearance：

N-butyl phthalate is a colorless oily liquid. It is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It is combustible though it may take some effort to ignite. It is used in paints and plastics and as a reaction media for chemical reactions.
