Ignition temperature dopes

Table XXXII.—-Rise of Ignition Temperature of Gasoline by Antiknock Dopes.

From these results it may be concluded that only oxidizable metals influence the ignition temperature and that metals forming peroxides are usually effective. The metal itself when in a state of incipient oxidation is the effective part of the organo-metallic dopes that suppress detonation in an engine, and this metallic oxide is the seat of the action on the combustion process. The most effective metals, with the exception of iron and nickel, are molten and vaporizable at the ignition temperatures. 

Use and exposure Diborane is a colorless gas at room temperature with a repulsive, sweet odor. It mixes well with air and easily forms explosive mixtures. Diborane will ignite spontaneously in moist air at room temperature and can cause explosions. Diborane is used in rocket propellants and as a reducing agent, a rubber vulcanizer, a catalyst for hydrocarbon polymerization, a flame-speed accelerator, and a doping agent. Diborane is a very toxic and flammable gas used by chemists to make other compounds. It is also used in electronics to impart electrical properties in pure crystals. Industrial workers are exposed to diborane by breathing in its vapors in work areas. - ...
