    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing laurolactam in a high purity from cyclododecanone in a high efficiency.
    SOLUTION: This method for producing laurolactam by performing the reaction of starting cyclododecanone raw material with a mineral salt of hydroxylamine and converting the obtained cyclododecanone oxime by Beckmann rearrangement reaction is provided by controlling by ≤1,000 ppm each of the contents of oxygen atom-containing 12C hydrocarbon compounds, e.g. cyclododecenone or epoxycyclododecane and cycloaliphatic unsaturated 12C hydrocarbons contained in the cyclododecanone raw material as impurities.

    Abstract: PURPOSE: To obtain the subject high-purity compound without forming a by- product by making an isomerization inhibitor coexist in a catalytic hydration reaction system of cyclohexene, dehydrating a formed substance, then reacting it with hydroxylamine and further subjecting the reaction product to Beckmann rearrangement. CONSTITUTION: An isomerization inhibitor in an amount of preferably 240-390ppm such as a cyclic diene is made to coexist in a catalytic hydration reaction system of cyclohexene produced by partial hydrogenation of benzene to form cyclohexanol. Cyclohexanol is dehydrated into cyclohexanone, which is reacted with hydroxylamine to give cyclohexanone oxime. Cyclohexanone oxime is further subjected to Beckmann rearrangement to give the objective compound.
