Autoxidation of Ethers to Peroxides and Hydroperoxides02:23

Autoxidation of Ethers to Peroxides and Hydroperoxides

Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.

Amines to Sulfonamides: The Hinsberg Test

The Hinsberg test is a method to identify primary, secondary and tertiary amines, named after its pioneer, Oscar Hinsberg. Here, amines are treated with benzenesulfonyl chloride, also known as the Hinsberg reagent, in the presence of an excess of aqueous base, followed by acidification. Based on the nature of the amines, different changes are observed.
Generally, a primary amine reacts with the Hinsberg reagent to produce an N-substituted benzenesulfonamide. The electron-withdrawing sulfonyl...
Physical Properties of Amines01:26

Physical Properties of Amines

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

Summary
This summary is machine-generated.

Fenhexamid fungicide residues on grapes decrease rapidly post-treatment. Wine production methods impact residue levels, but fenhexamid does not affect fermentation, nor is it degraded by it.

Area of Science:

  • Agricultural Chemistry
  • Food Science
  • Microbiology

Background:

  • Fungicides like fenhexamid are used on grapes to prevent spoilage.
  • Understanding fungicide behavior during winemaking is crucial for food safety and quality.

Purpose of the Study:

  • To investigate fenhexamid residue dynamics on grapes and during winemaking.
  • To assess the impact of fenhexamid on alcoholic and malolactic fermentation microflora.
  • To develop a method for quantifying fenhexamid residues.

Main Methods:

  • Residue analysis on grapes over time.
  • Fenhexamid quantification in wine from different vinification processes (with/without skins).
  • Microbiological assessment of fermentation processes in the presence of fenhexamid.
  • Gas chromatography with nitrogen-phosphorus detection (GC-NPD) for residue determination.

Main Results:

  • Fenhexamid residues on grapes decreased significantly in the first week and stabilized thereafter.
  • Residue reduction in wine varied: 49% decrease in wine without skins, 62% in wine with skins.
  • Fenhexamid presence did not inhibit alcoholic or malolactic fermentation.
  • No degradation of fenhexamid was observed during fermentation.

Conclusions:

  • Fenhexamid residues dissipate on grapes but persist through winemaking.
  • Vinification with skins leads to greater fenhexamid reduction.
  • Fenhexamid is compatible with wine fermentation microflora and processes.
  • A reliable GC-NPD method is available for fenhexamid residue monitoring.
