[2] As aforementioned, titanium catalysts predominantly produce the important cis,trans,trans- isomer.
[3] All of the isomers of 1,5,9-cyclododecatriene are colorless, possess typical terpene-like odors, and have low melting points.
Pure cyclododecanone (3b) can be produced through the dehydrogenation of the mixture over copper or copper-chromium catalysts on an active support at a temperature range of 230–245 °C and atmospheric pressure.
This in turn led to concerns for global production of finished goods, particularly in the automotive industry.
[10] Other biobased polyamides, not dependent on laurolactam or CDT, have been put forward as alternative materials.
