Synthesis of chemicals such as benzidine, quinoline, azobenzene, pyroxylin
compounds, and isocyanates.
Insects were dipped into a collodion solution (Collodion Flexible USP, Alcohol 22%, Ether 67%, Pyroxylin
4.75%, Camphor 2% and Castor Oil 3%, HUMCO, Texarkana, TX 75501), and allowed to stand at room temperature until the layer was solidified but not hardened (approximately 45 min) (Delp 1954; Kimbrough 1963).
