Precautions For Use Of Organic Peroxides


It is very important that the peroxide should always be stored at the appropriate temperature to store them in the original container to reduce the chance of being contaminated, especially if it is strongly acid contaminated. Care should be taken Organic Peroxides when using ketone peroxides because ketone peroxides react quickly when the transition metal salt concentration is very small. Organic peroxide in the transport should be as far as possible shock, anti-friction, anti-upside down, should wear protective equipment in use, to avoid sticking to the skin or into the eyes. The disposal of organic peroxides can be used for incineration, hydrolysis, deep burial and other methods.

Organic peroxides are liquid or solid organic compounds containing derivatives of a divalent -O-O- structure and one or two Organic Peroxides hydrogen atoms which are considered hydrogen peroxide to be substituted by an organic group. Organic peroxides are substances or mixtures that can cause exothermic self-accelerating decomposition, heat instability. In addition, they may have one or more of the following properties: (a) explosive decomposition; (b) rapid combustion; (c) sensitive to impact or friction; and (d) a dangerous reaction to other substances.

Organic Peroxides The test series A-H, as described in Part II of the United Nations Manual on Tests and Standards for the Transport of Dangerous Goods, is divided into seven categories according to the following principles:

    (1) organic peroxides, such as in the package, can be detonated or quickly deflagration, for the A-type organic peroxide;

    (2) any explosive organic organic peroxide, such as in the package, neither detonation nor rapid deflagration, but easy to occur in the package of hot blast will be classified as B-type organic peroxide;

    (3) any organic peroxide with explosive properties, such as in the package, can not be detonated or quickly deflagration or thermal explosion, then as a C-type organic peroxide;

    (4) Organic Peroxides organic peroxides, if in laboratory tests:

    1) part of the detonation, not quickly deflagration, heating in closed conditions do not show any drastic effect;

    2) no detonation, slow deflagration, heating in closed conditions do not show any drastic effect:

    3) does not initiate or deflate at all, and exhibits moderate effect when heated under closed conditions;

    It is designated as D-type organic peroxide;

    (5) organic peroxides, in the laboratory test, neither detonation nor deflagration, in the closed conditions of heating only show a weak effect or no effect, then as E-type organic peroxide;

    (6) organic peroxides, in the laboratory test, not only in the cavitation state detonation nor deflagration, in the closed conditions only show a weak effect or ineffective, and the explosion is weak or no explosive force, then As F-type organic peroxides;

    (7) organic peroxides, in laboratory tests, both in the cavitation state of the detonation or never deflagration, in the closed conditions show no effect, and without any explosive force, is defined as G-type organic peroxide But the Organic Peroxides substance or mixture must be thermally stable (the self-accelerating decomposition temperature of the 50 kg package is 60 ° C or higher) and the desorption dilution of the desensitized diluent used for the liquid mixture is not less than 150 ° C. If the organic peroxide is not thermally stable, or if the desorption dilution of the desensitized diluent is below 150 ° C, it is classified as an F-type organic peroxide.
