Hydroxy Group Formation/Introduction TRIZ Cases
- Biomass Polyester Polyol Envelope for Degradable Controlled-Release Fertilizer
A biomass-based polyester polyol cross-linked with MDI forms a degradable fertilizer envelope that lowers resin cost and sustains nutrient release for 60-150 days.
- Synthesis of 1,2,5-Thiadiazolidin-1,1-dioxide Salt via Red-Al Reduction
Red-Al reduction replaces toxic reagents to simplify synthesis of 1,2,5-thiadiazolidin-1,1-dioxide salt for enterovirus 71 treatment.
- Alkylene Glycol Process Using Ejector Mixing in Single Reactor
Ejectors mix reactants in a single reactor, reducing capital costs and operational complexity while maintaining high conversion efficiency.
- Iron Thiolate Catalyst Peroxide Decomposition
Iron thiolate complexes decompose hindered organic peroxides under mild conditions, overcoming low reaction rates associated with harsh reductive methods.
- NAPOM Protecting Group Agents for Mild Hydroxy Deprotection
NAPOM agents introduce hydroxy protecting groups at room temperature, resolving harsh condition requirements and moisture sensitivity.
