实测物性
- 性状
- Butyl, decyl, cetyl, eicosyl methacrylate appears as a colorless liquid with a mild odor. Less dense than water and insoluble in water. Hence floats on water. (USCG, 1999) · N-butyl methacrylate appears as a clear colorless liquid. Flash point 130 °F. Less dense (7.5 lb / gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used to make resins adhesives, and oil additives.
