in the ethyl alcohol and the ether, does not dissolve in the water. When return to original state produces the bitter almond oil camphor. |
| Chemical Properties |
The yellow crystallizes, the melting point: 95℃, has the optical rotation, the relative density :1.23, the boiling point :346-348℃, dissolves in the ethyl alcohol, the ether and so on organic solvent, does not dissolve in the water, when the return to original state produces the bitter almond oil camphor. |
| Use |
1. uses in the photosensitizer, the organic synthesis intermediate, also being possible to serve as the bond and so on.
2. Organic synthesis intermediate, also uses in the pesticide. This serves as the ultraviolet ray solidifies the resin (the UV resin) the photosensitizer to have the future very much. The dibenzoyl is broad to the ultraviolet ray sensitization's wavelength range. Bitter almond oil camphor below 3400A, bitter almond oil camphor alkyl oxide below 3900A. But the dibenzoyl below 4800A, may in the very wide wave length area sensitization, therefore may use in the heavy film resin the solidification, this is the characteristic which in before UA resin sensitization did not have. Moreover after solidifying, does not have the smell, therefore is suitable for the printing ink which manufactures the food packing to use and so on.
3. Serves as the medicine intermediate, the ultraviolet ray to solidify the resin the photosensitizer and so on. |
