Acrylic Acid → (+)-Limonene

Reaction Steps

Photopolymer plates based on a terpolymer of butadiene, acrylonitrile, and acrylic acid were processed as in Example 1 with this solvent. Wash time for this type plate in this solution was 18 minutes. Again the plate quality was superior to that obtained with perchloroethylene under the same conditions. In addition, the washed-out (uncured) photopolymer tended to separate from this washout solution. After standing for several hours the polymer could easily be removed from the solution with a wire screen. This allowed extended use of the washout solution because the spontaneous polymer separation prevented a build up of photopolymer, permitting continued use of the solution; up to approximately 200-300 square feet of plate area could be processed without distillation. Again plate quality was equivalent to that obtained with perchloroethylene at a higher exposure time.
