| Hazard Information | Back Directory | [Chemical Properties]
Dry PowderSolid; very faintly beige crystalline lumps. Virtually insol in water. | [Uses]
Laurolactam (CAS 947-04-6) functions primarily as a polyamide monomer (e.g., PA6/PA12) in plastics and packaging applications. Trace amounts can persist as residuals or impurities and may migrate under certain conditions. Analytical testing focuses on identity confirmation and migration assessment under worst‑case time/temperature/simulant conditions to support material qualification and compliance. It is included in the Union list of Commission Regulation (EU) No 10/2011 for plastic materials and articles intended to come into contact with food.

ChEBI: Laurolactam is an azamacrocycle and a keratan 6'-sulfate. | [Preparation]
One route to dodecyllactam is from butadiene as follows:
Butadiene is trimerized with a Ziegler-Natta catalyst to give 1,5,9-cyclododecatriene
which is then hydrogenated to cyclododecane. Dodecyllactam
is then obtained by a series of reactions similar to those used to prepare
caprolactam from cyclohexane. | [Health Hazard]
The acute oral LD50 was 2,330 mg/kg bw (rat) with central nervous system stimulation (trembling, convulsive twitches, ataxia) as the main clinical sign appearing at about 1,580 mg/kg bw. The dermal LD50 was greater than 2,000 mg/kg bw (rat). Decreased food consumption and stagnation of body weight development were noted. Validacute inhalation studies are not available. Azacyclotridecan-2-one was not irritating to the rabbit skin or eye (OECD TG 404, 405). It was not sensitizing in aguinea pig maximization test (OECD TG 406; 1981). | [Purification Methods]
2-Azacyclotridecanone crystallises from CHCl3 and is stored over P2O5 in a vacuum desiccator. [Beilstein 26/1 V 566.] |
