Di Ammonium Phosphate (DAP)
·
DAP is used as a fertilizer.
When applied as plant food, it temporarily increases the soil pH.
·
DAP can be used as a fire
retardant. It lowers the combustion temperature of the material, decreases
maximum weight loss rates, and causes an increase in the production of residue
or char. These
are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount
of char formed reduces that amount of
available fuel and can lead to the formation of a firebreak. It is the largest component
of some popular commercial firefighting products.
·
DAP is also used as a yeast
nutrient in winemaking and
brewing mead; as an additive in
some brands of cigarettes purportedly as a nicotine
enhancer; to prevent afterglow in matches, in purifying sugar; as a Flux for
soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble
colloidal dyes on wool.
