Study and development of a Mannich based corrosion inhibitor for hydrochloric acid acidifying;

Synthesis and antiinflammatory activity of the Mannich bases of the substituted cyclopentanones;

According to the characteristics of oil reservoir at high temperature, the two corrosion inhibitors that are imidazoline and Mannich base were synthesized.

Study on preparation and antioxidant activity of dihydroquercetin mannich salt;

Dihydroquercetin mannich salt,a sihydroquercetin derivative,was prepared via mannich reaction.

Present research status of Mannich bases and Mannich base-prodrugs;

Through adjusting the molar ratio of ketone and aldehyde,amine,reaction time,temperature and pH,we obtained the Mannich base inter-medium which have the best corrosion inhibition efficiency,and then conducted quaternarization with benzyl chloride to get Mannich base quaternary ammonium salt.
