Hydrogen peroxide

CAS RN: 7722-84-1

Reactivities / Incompatibilities

Incompatible materials: Zinc, powdered metals, iron, copper, nickel, brass, iron and iron salts. /Hydrogen peroxide solution (>/= 30% to <50%)/
Ignition on contact with furfuryl alcohol; powdered metals (e.g., magnesium; iron); wood. Violent reaction with aluminum isopropoxide + heavy metal salts; charcoal; coal; dimethylphenylphosphine; hydrogen selenide; lithium tetrahydroaluminate; metals (e.g., potassium, sodium, lithium); metal oxides (e.g., cobalt oxide, iron oxide, lead oxide, lead hydroxide, manganese oxide, mercury oxide, nickel oxide); metal salts (e.g., calcium permanganate); methanol + phosphoric acid; 4-methyl-2,4,6-triazatricyclo [5.2.2.0(2,6)] undeca-8-ene-3,5-dione + potassium hydroxide; alpha-phenylselenoketones; phosphorus; phosphorus(V) oxide; tin(II) chloride; unsaturated organic compounds.
Oxidizable materials, iron, copper, brass, bronze, chromium, zinc, lead, silver, manganese [Note: Contact with combustible material may result in SPONTANEOUS combustion].
Most cellulose materials contain enough catalyst to cause spontaneous ignition with 90% peroxide. ... Soluble fuels (acetone, ethanol, and glycerol) will detonate on admixture with peroxide of over 30% concentration, the violence increasing with concentration. Handling systems must exclude fittings of iron, brass, copper, Monel, and screwed joints caulked with red lead. ... Addition of charcoal to concentrated hydrogen peroxide results in violent decompositon.
The solid peroxide produced by action of hydrogen peroxide and nitric acid on thiourea (and possibly a hydrogen peroxidate of thiourea dioxide) decomposed violently on drying in air, with evolution of sulfur dioxide and free sulfur.
