Propagating reaction fronts generated in the autocatalytic oxidation of formaldehyde by nitric acid have been investigated. The experimental values of the wave velocity ν and those of the maximal reaction rate r m at a given spatial coordinate have been described by the formulae ν = 2( Dk [CH 2 (OH) 2 ] 0 ) 1/2 and r m = 0.247 × k [CH 2 (OH) 2 ] 0 2 , respectively, ( D and k constants). Similarities and differences to other nitric acid oxidations have been discussed. © 1995 John Wiley & Sons, Inc.
