Chemical explosives sensitivity

Chemical Reactivity - Reactivity with Water No reaction Reactivity with Common Materials Avoid contamination with combustible materials, various inorganic and organic acids, alkalies, alcohols, amines, easily oxidizable materials such as ethers, or materials used as accelerators in polymerizations reactions Stability During Transport Extremely explosion-sensitive to shock, heat and friction. Self-reactive Neutralizing Agents for Acids and Caustics Not pertinent Polymerization Not pertinent inhibitor of Polymerization Not pertinent. 

Masurites. Coal mining, low freezing expls, manufd from 1903-11 by Masurite Explosives Co of Youngstown, Ohio. They consisted essentially of Amm nitrate (up to 93%) and waste oils from paint factories, together with certain chemicals to sensitize the mixt Refs 1) W.H.

The cross-dimerization reaction is very commonly employed for the manufacture of intermediates for synthetic musks, which have become an important class of perfumery chemicals. Synthetic musks have been the target of extensive research over the years due to a conservation order placed on the musk deer. Nitro musks are being steadily replaced by non-nitro polycyclic musks becau.se of technical drawbacks and health aspects of the former, which are explosive, sensitive, and virtually nonbiodegradable. Non-nitro musks, on the other hand exhibit better stability to light and alkali, and more nearly duplicate the odour of the macrocyclic musks occurring in nature. Indian musk odorants are easily soluble in alcohol and perfume compositions. They have the added advantage of non-discoloration in soap and domestic products. In view of the low price, their future in the perfume industry appears very promising.

Hazard Strong oxidizing agent ignites violently with combustibles. Shocksensitive may explode when exposed to heat or by spontaneous chemical reaction. Sensitive, high explosive when contaminated with reducing materials. Skin irritant. 

The American National Standards Institute (ANSI) has established a voluntary standard for chemical labeling, ANSI Z129.11994, Hazardous Industrial Chemical Precautionary Labeling, which includes readily identifiable symbols for poisons, corrosives, flammables, and explosives. Irritants, combustible liquids, pyrophoric chemicals, oxidizers, sensitizers, physiologically inert vapors, gases and other hazardous materials are also addressed. 

The importance of reacting surfaces in liquid and gelatin explosives has long been known from experience with liquid nitroglycerine and gelatin dynamites. Aeration is an important aspect of the sensitivity of these liquid and semiliquid explosives. More recently this has been reemphasized by the observed effects of aeration on the sensitivity of slurry explosives sensitized by aluminum or other nonexplosive fuels. The sensitivity, indeed the propagation of the detonation wave, in these slurry explosives is initially associated with small gas bubbles which act as reaction centers for the essential chemical reactions.
