Preparation By Ester-Hydroxy Reaction TRIZ Cases
- Aryl Ester Carboxylic Acid Synthesis Without Oligomer Formation
This case uses tert-butyl transesterification and selective deprotection to produce aryl ester carboxylic acids without oligomers.
- Low-Pressure Glycerol Hydrogenation Catalyst for 1,2-Propanediol
Copper heterogeneous catalyst enables low-pressure glycerol hydrogenation to produce 1,2-propanediol without extensive pre-treatment.
- Biodiesel Production From Impure Feedstocks Using Esterification
Esterification pre-treats impure feedstocks to remove free fatty acids, enabling high-quality biodiesel output from low-cost materials.
- 2-Octyl Acrylate Purification via Catalyst Precipitation
Water precipitation removes the titanium catalyst before distillation, reducing column count while maintaining over 99.3% purity of 2-octyl acrylate.
- Tetraisopentyl Esters Plasticizer Composition
Tetraisopentyl esters of butanetetracarboxylic acid replace phthalates by optimizing 2-methylbutyl radical proportions for stability.
- Vacuum Fractionation of Alkyl Esters for Aviation Biokerosene
Vacuum fractionation isolates light alkyl esters with freezing points below -10°C, resolving distillation range mismatches in aviation fuel production.
