Poison by
intraperitoneal route. Moderately toxic by
ingestion and inhalation. Human systemic
effects by ingestion: changes in structure or
function of esophagus, nausea or vomiting,
other gastrointestinal effects. A moderate
skin and eye irritant. Questionable
carcinogen with experimental tumorigenic
data. A shock-sensitive explosive. When

smoke and irritating fumes. | [Hazardous Substances Data]
1338-23-4(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
Colorless liquid. Strong irritant to skin and tissue. Used as an initiator for room temperature cure of unsaturated polyester resins. | [Reactivity Profile]
METHYL ETHYL KETONE PEROXIDE is a strong oxidizing agent. May be ignited by heat, sparks or flame and undergoes self-accelerating decomposition. Explosive decomposition occurs at 230° F. Sensitive to sunlight. Ignition and/or explosion may occur if mixed with readily oxidizable materials. Reacts with combustible materials such as wood, cloth or organic materials, with chlorine, and with metals (iron, copper and their alloys and aluminum and its alloys). Incompatible with strong oxidizing agents, strong reducing agents, natural rubbers, synthetic rubbers and chemical accelerators. Incompatible with heavy metals, acids and bases. | [Hazard]
Fire risk in contact with organic materials.Strong irritant to skin and tissue. Liver and kidneydamage. | [Health Hazard]
Extremely destructive to tissue of the mucous membranes, upper respiratory tract, eyes, and skin. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. | [Potential Exposure]
MEKP is used as a curing agent for
thermosetting polyester resins and as a crosslinking agent
and catalyst in the production of other polymers | [Fire Hazard]
Behavior in Fire: Explosive. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy. | [Shipping]

Hazard Class: 5.2; Labels: 5.2-Organic peroxide, Technical
Name Required.
| [Incompatibilities]
Forms explosive mixture with air (flash
point varies). MEKP may exist in several different structures; decomposition temperatures may vary. Pure substance is shock-sensitive. Explosive decomposition above
176F/80C (also reported @ 230F/110C). Keep away
from sources of ignition, heat, sunlight. A strong oxidizer.
Violent reaction with strong acids; strong bases; reducing
agents; combustible substances, organic materials; chemical
accelerants; oxides of heavy metals; salts, trace contaminants; amines. May accumulate static electrical charges,
and cause ignition of its vapors. Commercial product is
diluted with 40% dimethyl phthalate, cyclohexane peroxide; or diallyl phthalate to reduce sensitivity to shock. | [Description]

MEKP, an organic peroxide, is a colorless
liquid. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal.
MEKP may be destroyed by adding 20% NaOH solution
slowly in a quantity about 10 times the weight of MEKP.
Incineration is recommended if NaOH treatment is not
used | [Application]
2-Butanone peroxide can be used as the following reactants:
Studies of the adiabatic runaway reaction of Me Et Ketone peroxide.
Quantitation of metal ions in archaeological glass via abrasive stripping square-wave voltammetry.
Imaging of hydrogen peroxide and hydrogen peroxide-scavenging substances by photon emission.
Synthesis of oligonucleotides via phosphoramidite method.
Oxidation of nucleoside phosphites into phosphates.
Comparing the relative effectiveness of human plasma glutathione peroxidase as a catalyst for reduction of hydroperoxidases.
2-Butanone peroxide can also be used as a direct electrochemical catalyst analyte for immobilized Hb in ethanol-water mixtures. | [Preparation]
2-Butanone peroxide is obtained by reacting methyl ethyl ketone with hydrogen peroxide (hydrogen peroxide) in the presence of sulfuric acid. After oxidation, neutralization, separation, dehydration, standing, filtration, and finally adding the solubilizing agent to obtain the finished product. | [storage]
MEK peroxide is diluted in a solvent or dispersedin a plasticizer, which greatly reducesits shock sensitivity. It is stored in a refrigeratorin a well-ventilated area and wellseparated from other chemicals. Peroxidewith an active oxygen content >9% maynot be shipped. Diluted material is shippedin metal drums with polyethylene liners orpolyethylene-lined paper bags in woodenboxes. |
