ozonide

In IR spectra, the bands corresponding to both C = C (1654 [cm.sup.-1]), = C - H (3009 [cm.sup.-1]) stretching and to ozonide C-O stretching (1105 [cm.sup.-1]) are the most important.

During one of these visits they also returned to studies of the ozone-ethylene system in an attempt to produce the primary ozonide of ethylene.

However, the researchers discovered that, when the fluid is acidic--a pathological condition found in asthmatics--ascorbic acid instead reacts with ozone to form potentially harmful compounds ca]led ozonides.

Due to absorption reaction ozone reacts on DPE and forms an ozonide as intermediate, which upon hydrolysis yields pyridine-4-aldehyde (PA).

This structure decomposes to Zwitterion (1) and a carbonyl compound (2), which can recombine to a normal ozonide (3).

By the reaction between ozone and the super-oxide anion radical the ozonide anion radical [O.sub.3.sup.*-] formed, which decomposes immediately giving [sup.*]OH radical.

[O.sub.3] is also hypothesized to initiate intracellular oxidative stress through ozonide and hydroperoxide formation (Pryor 1992).

This reaction produces several oxygenated compounds such as hydroperoxides, ozonides, aldehydes, peroxides, diperoxides, and polyperoxides [5].

A systematic review indicates that the reaction between [O.sub.3] and biomolecules to form ozonides and free radicals triggers inflammatory responses and systemic oxidative stress in the cardiorespiratory system (Srebot et al.

In addition to peroxides, peroxyhydrates, peroxopolyoxometallates, superoxides, and ozonides are known peroxo compounds.

Indeed, it is well known that ozone reacts strongly with the unsaturations of polyethylene to form unstable ozonides. Then, the decomposition of ozonides produces inert substances such as alcohol, ketone or acid.

So you are infusing peroxides (German literature calls them ozonides) that hang around for several weeks.
