MAPP/oxygen was advantageously used in underwater cutting, which requires high gas pressures (under such pressures acetylene can decompose explosively, making it dangerous to use [5]). However, underwater oxy/fuel gas cutting of any kind has been largely replaced by exothermic cutting [6] because it cuts more quickly and safely.
Whereas purified propyne is expensive, MAPP gas could be used to cheaply generate large amounts of the reagent. [8] Propyne, along with 2-butyne, is also used to synthesize alkylated hydroquinones in the total synthesis of vitamin E. [9]
MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling.
The most commonly known type of MPS gas is the discontinued MAPP gas. [2] As a fuel gas, it burns hotter than propylene, propane or natural gas. See also.
But they are sensitive to produce that emits the gas. That’s why you should store greens and salads away from bananas, apples, tomatoes, and avocados, which can cause them to wilt more quickly.
In industry and workshops, propylene is used as an alternative fuel to acetylene in Oxy-fuel welding and cutting, brazing and heating of metal for the purpose of bending. It has become a standard in BernzOmatic products and others in MAPP substitutes, [20] now that true MAPP gas is no longer available.
