Cyclododecan - Reference Information
| LogP | 7.6 at 25℃ |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | organic intermediate, used as monomer of nylon, intermediate of dodecacolactam. |
| production method | 1. Preparation of cyclododecatriene by hydrogenation. It can also be obtained by directly trimerizing 1,3-butadiene in the C4 fraction obtained from petroleum cracking to cyclododecatriene and then hydrogenating it. The catalyst used for the hydrogenation was skeleton nickel, and the reaction was carried out at a pressure of 1.961-2.941MPA and a reaction temperature of 80-100 °c. The whole reaction process is long and complicated. With cyclododecanone as raw material, with zinc Mercury and hydrochloric acid for reduction system. |
