Alkenyl Succinic Anhydride Structure Influences the Surface Activities of Gelatin Derivatives

Synthesis of Five and Six-Membered Heterocycles Using Activated Nitriles for Industrial Applications

The aim of this study is a synthesis of new bioactive heterocyclic compounds incorporated fatty chain for use in different industrial applications. Cyanoacetamide derivative (2) was successfully transferred into five and six membered heterocyclic derivatives by the reaction with various chemical reagents. Addition number of moles of propylene oxide to these compounds gave nonionic surface-active agents having a good solubility, biodegradability and hence lowers the toxicity to human beings and becomes environmentally friendly. The antimicrobial and surface activities were investigated that showed the most of them have pronounced activity, which makes them suitable for diverse applications like the manufacturing of drugs, pesticides, emulsifiers, cosmetics, etc.

Switchable foam control by a new surface-active ionic liquid

Switchable foam control was achieved for aqueous solution of new surface-active ionic liquid ([BAzoTMA][NTf₂]) by alternatively adding cucurbit[7]uril and spermine.
