摘要： PROBLEM TO BE SOLVED: To make it possible to obtain a substitutive fire extinguishing chemical equivalent to the fire extinguishing capacity of a regulated halon with less influence on a global warming effect without the destruction of the ozonosphere by using the fluorine-contained ketone expressed by a specific formula as the substitutive fire extinguishing chemical.
SOLUTION: The substitutive fire extinguishing chemical expressed by the formula is used as the essential component of the substitutive fire extinguishing chemical. In the formula, (n) denotes an integer from 4 to 8; (m) denotes an integer of 0 or 1; R
1 denotes a methyl group or ethyl group. At least one fluorine-contained ketone selected from CF
3 CF
2 CF
2 CF
2 COCH
3 , CF
3 CF
2 CF
2 CF
2 CF
2 COCH
3 and (CF
3 )
2 CFCF
2 CF
2 COCH
3 is used as the fluorine-contained ketone. The substitutive fire extinguishing chemical has a hydrogen atom and carbonyl bond in the molecule and is, therefore, shorter in the atm. life than perfluorohydrocarbon and since the chemical does not contain a bromine atom, the substitutive fire extinguishing chemical is adequate as the substitutive fire extinguishing chemical of the regulated halon.
