Abstract:The synthetic process of 2,6-dimethy-N-tridecyl morpholine was improved using 2,6-dimethylmorpholine and isotridecanol as raw materials. Process conditions include the ratio of raw materials, reaction temperature and dropping time of 2,6-dimethylmorpholine were optimized. The optimized conditions was obtain as following: n(isomeric tridecanol)∶n(2,6-dimethylmorpholine) was of 1.2∶1.0, the reaction temperature was of 260~280 ℃, and the 2,6-dimethylmorpholine dropping time was of 8~10 h. Under these conditions, the yield and purity of n-isotridecyl 2,6-dimethylmorpholine were 86.9% and 96% respectively. The product structure was confirmed by IR and MS. The process has the advantages including low cost, short process flow, less investment, simple operation, high yield and industrialization.
Key words:tridecyl alcohol; 2,6-dimethylmorpholine; one-step method
