Preparation By Oxidation Reactions TRIZ Cases

Zirconium-catalyzed asymmetric carboalumination generates chiral intermediates that bypass difficult purification steps to achieve ≥99% enantiomeric purity.

A chemiresistive sensor combines platinum-polyoxometalate catalysts with single-walled carbon nanotubes to detect methane and hydrogen sulfide.

Biphasic conversion of dimethyl benzyl alcohol to cumene hydroperoxide minimizes heavy by-products and optimizes phenol yield.

Rh-R-Mo-V composite oxide activates methane at lower temperatures, reducing harmful CO production while maintaining high product selectivity.

Particulate rhodium catalyst on micro-porous silica converts hydrocarbons to ethanol and acetic acid, resolving selectivity limits in existing processes.

Purifying diols through controlled vacuum distillation below 250°C to maintain favorable color quality.

Sequential side draw columns remove low, medium, and high boilers from dehydrogenation mixtures to achieve 98% purity.

Converting low-value paraffins via dialkyl peroxide intermediates eliminates expensive C4 olefins while producing high-cetane diesel and high-octane alkylate.

Segmented catalyst beds with varying temperatures extend single-pass service life and reduce regeneration frequency.
