Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide02:44

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

10.2K
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.

Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids02:04

Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids

5.8K
Diols are compounds with two hydroxyl groups. In addition to syn dihydroxylation, diols can also be synthesized through the process of anti dihydroxylation. The process involves treating an alkene with a peroxycarboxylic acid to form an epoxide. Epoxides are highly strained three-membered rings with oxygen and two carbons occupying the corners of an equilateral triangle. This step is followed by ring-opening of the epoxide in the presence of an aqueous acid to give a trans diol.

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate02:21

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate

11.5K
Alkenes can be dihydroxylated using potassium permanganate.  The method encompasses the reaction of an alkene with a cold, dilute solution of potassium permanganate under basic conditions to form a cis-diol along with a brown precipitate of manganese dioxide.

Oxidative Cleavage of Alkenes: Ozonolysis01:46

Oxidative Cleavage of Alkenes: Ozonolysis

10.4K
In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

Area of Science:

  • Materials Science
  • Combustion Science
  • Surface Engineering

Background:

  • Biomass combustion is a vital energy source globally.
  • Soot accumulation on combustor walls impairs heat transfer efficiency.
  • Effective soot removal is crucial for optimizing combustion processes.

Purpose of the Study:

  • To investigate the impact of microtextured surfaces on soot accumulation and oxidation.
  • To determine the optimal microtexture parameters for enhanced soot removal.
  • To assess the applicability of microtextured surfaces in biomass combustors.

Main Methods:

  • Fabrication of randomly microtextured and grooved glass surfaces via sandblasting and laser ablation, respectively.
  • Combustion experiments using paraffin wax as a model for wood-based soot.
  • Analysis of soot oxidation rates and surface characteristics using X-ray photoelectron spectroscopy (XPS).
  • Testing of microtextured stainless steel surfaces.

Main Results:

  • Randomly microtextured glass demonstrated a 71% reduction in time to oxidize 90% of soot coverage compared to smooth glass at 530°C.
  • Grooved microtextures with widths between 15-50 µm significantly enhanced soot oxidation.
  • Optimal groove width for enhanced soot oxidation was identified; larger widths (85 µm) diminished the effect.
  • XPS confirmed superior soot removal on microtextured surfaces at the sub-nanometer scale.
  • Enhanced soot oxidation was also observed on microtextured stainless steel.

Conclusions:

  • Microtextured surfaces effectively minimize soot accumulation by promoting accelerated soot oxidation.
  • Surface topography, particularly sharp features and conformality, plays a key role in enhancing oxidation.
  • Microtextured stainless steel shows promise for improving the performance and durability of biomass combustors.
