2-Butanone peroxide Chemical Properties,Uses,Production

Chemical Properties

colourless liquid of high viscosity

Chemical Properties

MEKP, an organic peroxide, is a colorless liquid.

Uses

Manufacture of acrylic resins, hardening agentfor fiberglass-reinforced plastics.

Uses

MEK peroxide it is used to initiate thepolymerization of ethylene, styrene, vinylchloride, and other monomers; and for roomtemperature curing of polyester resins.

General Description

Colorless liquid. Strong irritant to skin and tissue. Used as an initiator for room temperature cure of unsaturated polyester resins.

Reactivity Profile

2-Butanone 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.

Health Hazard

MEK peroxide is a strong skin and eye irritantwith moderate acute and subchronic toxicity.Its toxicity is greater than di-t-butylperoxide and benzoyl peroxide. Inhalationof its vapors can cause injury to lungs withsymptoms of gross hemorrhages and hyperemia(Floyd and Stockinger 1958). Exposureto high concentrations may have damagingeffects on the liver and kidney. In humans,ingestion of 30–40 g can be toxic, whichmay cause gastrointestinal pain, nausea, andvomiting.
LC50 value, inhalation (mice): 170 ppm/4 h
LD50 value, intraperitoneal (rats): 65 mg/kg
LD50 value, oral (mice): 470 mg/kg
Its carcinogenicity is not yet fully established.It is reported (NIOSH 1986) to causetumor in mice.

Fire Hazard

Behavior in Fire: Explosive.

Safety Profile

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 heated to decomposition it emits acrid smoke and irritating fumes.

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

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.

Shipping

UN3105 Organic peroxide type D, liquid, 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.

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
