Permissible camphor restrict (PEL) in the ambient air is 2 mg/m3 at exposure time (TWA) not greater than eight hours. William Perkin published another synthesis a short time later. The first complete complete synthesis of camphoric acid was published by Komppa in 1903. Its inputs were diethyl oxalate and 3,3-dimethylpentanoic acid, which reacted by Claisen condensation to yield diketocamphoric acid. The background of Gustaf Komppa's synthesis was as follows.
