The material meets the definition of an explosive as prescribed in subpart C of this part, in which case it must be classed as an explosive (applies to acetone peroxide, for example) The material is forbidden from being offered for transportation according to 49CFR 172.101 of this subchapter or 49CFR 173.21;
Thus, organic peroxides are useful as initiators for some types of polymerization, such as the acrylic, unsaturated polyester, and vinyl ester resins used in glass-reinforced plastics. MEKP and benzoyl peroxide are commonly used for this purpose. However, the same property also means that organic peroxides can explosively combust.
Organic peroxide type D, liquid UN 3106: 5.2: Organic peroxide type D, solid UN 3107: 5.2: Organic peroxide type E, liquid UN 3108: 5.2: Organic peroxide type E, solid UN 3109: 5.2: Organic peroxide type F, liquid UN 3110: 5.2: Organic peroxide type F, solid UN 3111: 5.2: Organic peroxide type B, liquid, temperature controlled UN 3112: 5.2 ...
Oxidizing substances – Substances which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material Division 5.1 Organic peroxides – Organic substances which contain the bivalent –O–O– structure and may be considered derivatives of hydrogen peroxide ...
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide with the formula [(CH 3)(C 2 H 5)C(O 2 H)] 2 O 2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers. [3] It is derived from the reaction of methyl ethyl ketone and hydrogen peroxide under acidic conditions.
Inhalation Hazard: Any quantity of a material that is in Hazard Zone A or B (see Assignment of packing groups and hazard zones below). Toxic : May be used instead of POISON placard on 454 kg (1001 lb) or more gross weight of poisonous materials that are not in Hazard Zone A or B (see Assignment of packing groups and hazard zones below).
HMTD is an organic peroxide, a heterocyclic compound with a cage-like structure. It is a primary explosive . It has been considered as an initiating explosive for blasting caps in the early part of 20th century, mostly because of its high initiating power (higher than that of mercury fulminate ) and its inexpensive production.
However, TBPB is one of the safest peresters or organic peroxides in handling. [4] The main decomposition products of tert -butyl peroxybenzoate are carbon dioxide , acetone , methane , tert -butanol , benzoic acid and benzene .
