Organic Compounds Purification/Separation/Stabilisation TRIZ Cases

Thin film evaporators distill hydrogenated sugar to bypass expensive catalysts and achieve 99% purity.

Ring magnets suspend magnetic particles to separate nucleic acids from FFPE tissue debris under non-chaotropic conditions.

Adding radical scavengers prevents radiolysis of unstable intermediates, thereby improving radiochemical yields in high-activity synthesis.

Replacing trimethylsilyl chloride with hexamethyldisilazane eliminates ammonia by-products that degrade product purity and complicate work-up procedures.

Weak acid buffers maintain radiochemical purity above 95% during autoclaving, preventing radiolysis degradation.

A quinone methide and ammonium salt composition inhibits free-radical polymerization of ethylenically unsaturated monomers.

Combining p-toluidine and m-toluidine accelerators stabilizes low-temperature curing while maintaining high-temperature load values.

Rotation distributes heat across the material bed to increase sublimation rates while preventing decomposition of thermally sensitive materials.

Converts oil-soluble calcium compounds into water-soluble forms using 2-oxopropanal derivatives for separation.

A hydrogen-occluding metal catalyst removes dissolved oxygen from isopropyl alcohol through chemical reaction.

Acid modified red mud catalyst expands surface area to increase isomerization yield, avoiding ethylene dimerization costs.

Treating lower-grade amino acids with 2-propanol reduces bioburden and enhances crystallinity to meet pharmaceutical standards without expensive feedstock.

Fatty acid ethyl and methyl esters dissolve plant materials to extract cannabinoids, reducing energy consumption and unwanted byproducts.

Dispersing liquid CO2 as fine emulsion droplets prevents buoyancy leakage and accelerates methane replacement in ocean sediments.

Recirculating mother liquid via a bypass line to a flash reactor increases conversion rate and reduces energy consumption.

pH-adjusted liquid-liquid extraction isolates aminoalcohols and glycols from taurine waste, enabling stream recycling to reduce purge volumes.

Washing organic solvents with aqueous hydrazine removes residual tribromides, preventing catalyst loss and allowing bromine regeneration.
