Preparation of Octenidine: The reaction of pyridine and thionyl chloride to obtain compound (I). Mixing phenol and compound (I), and reacting at 160 °C. Adding octylamine hydrochloride, and reacting at 220 °C. Cooling, adding 2mol / L hydrochloric acid and distilled to remove phenol. Then adding 10% sodium hydroxide solution to alkalify. Cooling, filtering to collect solid which is dissolved with dilute hydrochloric acid, bleaching, and alkalized with 10% sodium hydroxide solution. Filtering to collect solid, washing and drying to get white crystalline compound (Ⅲ). The yield is 60%. Compounds (Ⅲ) and dichloro-decane react at 120 °C. Cooling to 100 °C, adding dimethylformamide, stirring solution, and cooling naturally. Filtering to collect solid to get white crystalline product. The yield is 70%.

Uses of Octenidine: It is broad spectrum antibiotic and local anti-infectives. It can effectively inhibit streptococcus sanguis, actinomyces monocytogenes and so on. And the inhibitory effect of dental plaque and gingivitis is very good.
