Reaction of some commonly used chemicals with Ozone.

These studies were conducted in atmosphere. It has been proven that contaminants in liquids are eliminated much faster with small amounts of O3.

Introduction:

Organic compounds react with Ozone in a process similar to combustion. The reaction of an organic compound with Ozone and the combustion of the same compound yield Carbon Dioxide and water as the main end-products. Ozone combines with most of the hetereo-elements found in organic compounds to produce the elemental oxide with the highest oxidation number.

Inorganic compounds of lower oxidation numbers react with Ozone to produce oxides, however, there are many inorganic compounds which will not react. A partial listing follows the reaction examples.

The compounds discussed in this report have been divided into groups according to commonly used organic and inorganic classifications to show products common to all the compounds in the group.

LIQUIFIED PETROLEUM GAS        General Formula: C_nH_2n+2

            Reaction: C_nH_2n+2 + O₃ > (n+1)H₂O + O₂

MINERAL SPIRITS    General Formula and reaction same as LPG

            Both LPG and Mineral Spirits are mixtures of aliphatic, saturated hydrocarbons,

            therefore, only a generic formula was used to describe the reaction of both.

PROPANE      Formula: C₃H₈

            Reaction: C₃H₈ + 10O₃ > 4H₂O + 10O₂

IV. CHLORIDES

Chlorides are organic compounds which have one or more chlorine atoms in their structure. These compounds react with Ozone to produce hydrochlorites, which in turn decompose to produce chloride and release Oxygen, as shown in the reaction below:

            Cl₂O . 2Cl^-1 + ½ O₂

METHYLENE CHLORIDE (Dichloromethane)  Formula: CH₂Cl₂

            Reaction: CH₂Cl₂ + 4O₃ > CO₂ +H₂O + Cl₂O + 4O₂

TRICHLOROETHYLENE      Fromula: CHlCCl₂

            Reaction: 2CHlCCl₂ + 12O₃ > 4CO₂ + H₂O + 3Cl₂O + 12O₂

V. NITROGEN CONTAINING COMPOUNDS

HYDROGEN CYANIDE        Formula: HCN

            Reaction: 2HCN + 5O₃ -> 2CO₂ + H₂O + N₂ + 5O₂

AMMONIA    Formula: NH₃

            Reaction: 2NH₃  +  3O₃  à  3H₂O + 3O₂

SULFUR CONTAINING COMPOUNDS

These compounds generally react with Ozone to produce sulfur trioxide (SO₃), which, in the presence of water forms sulfuric acid.

HYDROGEN SULFIDE          Formula H₂S

            Reaction:  H₂S + O₃ -> H₂O + S + O₂

SODIUM BISULFITE Formula NaHSO₃

Reaction: NaHSO_{3 +} O₃ > NaHSO₄ + O₂

VII. OTHER

ALKYLATED SILICATES     General formula  (R_nSiO)_m

            Reaction: (R_nSiO)_m + O₃ > CO₂ + H₂O + SiO₂

NOTE: Alkylated Silicates produce SILICA (Silicon Dioxide) which is considerd a respiratory hazard.

NON-IONIC DETERGENTS             Formula: C_xH_y

            Reaction: C_xH_y + O₃  > CO₂ + H₂O + O₂

NOTE: Non-ionic detergents do not have a generic formula, therefore the formula given is used to define this class of compounds.
