ROSIN AMINE & THE DERIVATIVES
THE BIOBASED ACTIVE INGREDIENTS FOR SURFACTANTS
Development of Surfactants Utilizing Plant-based Resources
Gum rosin contains a large proportion of resins acids and fatty acids. The rosin derivative – rosin nitrile, which is prepared by the processes of ammonification and dehydration. And then rosin nitrile is reacted with hydrogen to prepare rosin amine.
According to the different of rosin materials, there have rich types of rosin amine, they include gum rosin amine, disproportionated rosin amine. polymerized rosin amine, hydrogenated rosin amine, etc. It appears lightly yellow color and has woody, ammonia smell. It is soluble in organic solvents, such as alcohols, ethers or hydrocarbons. Due to the amphipathic molecule feature, through the modification process, rosin amine can be prepared to anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants.

- A Nucleophilic Reagent
- Optical Activity and High-Resolution Rate
- Low Toxic and Organic
Now, rosin amine is a new choice of organic catalyst for asymmetric synthesis and drug-lead synthesis. Hydrogen bond activation becomes an important approach to active electrophilic reagents in the catalytic system of small molecular synthesis. Chinese researchers reported that novel rosin-derived amine thiourea bifunctional catalytic system appears excellent catalytic activity and optical activity.
