Common terminology for organic peroxidesIssuing time:2019-09-05 09:02
A liquid or solid organic substance containing a bivalent OO- structure and a derivative of one or two hydrogen atoms that may be considered hydrogen peroxide that has been replaced by an organic group. The term also includes organic peroxidation compounds (mixtures). Organic peroxides are substances or mixtures that can undergo exothermic self-accelerated decomposition and thermal instability. In addition, they may have one or more of the following properties: B) rapid combustion; C) sensitive to impact or friction; D) dangerous reactions with other substances Note: in laboratory tests, organic peroxides are easy to explode, deflagrate quickly or show violent effects when heated under closed conditions, which is considered to have explosive properties. reactive oxygen The ability to express the oxidation of organic peroxides in the form of oxygen (when oxygen :8.00) Self-accelerating decomposition temperature (SADT) The lowest temperature at which peroxides begin to accelerate decomposition in solid packaging suitable for storage and transportation. half-life period The time required for organic peroxides to decompose 50% at a given temperature Alarm temperature (Tem) Temperature at which first aid measures (such as removal of organic peroxides) must be taken. From the self - accelerating decomposition temperature obtained. Control temperature (Te) The highest temperature at which the product can be safely stored. From the self - accelerated decomposition temperature calculated |
