MSDS Information

• Methyl ethyl ketone peroxide

メチルエチルケトン過酸化物 化学特性,用途語,生産方法

• 外観

  無色～ほとんど無色透明液体

• 用途

  不飽和ポリエステル樹脂硬化剤

• 化学的特性

  Methyl ethyl ketone peroxide (2-Butanone peroxide) is an organic peroxide with the formula [(CH3)(C2H5)C(O2H)]2O2. MEKP is a colorless oily liquid. It is widely used in vulcanization (crosslinking) of polymers.

• 主な応用

  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.

• 製造方法

  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.

• 一般的な説明

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

• 反応プロフィール

  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.

• 危険性

  Fire risk in contact with organic materials.Strong irritant to skin and tissue. Liver and kidneydamage.

• 健康ハザード

  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.

• 火災危険

  Methyl Ethyl Ketone Peroxide (2-Butanone peroxide) is a combustible and reactive liquid that may burn slowly at first, and after heating can burn violently and explosively.

• 安全性プロファイル

  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.

• 貯蔵

  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.

• 輸送方法

  UN3105 Organic peroxide type D, liquid, Hazard Class: 5.2; Labels: 5.2-Organic peroxide, Technical Name Required.

• 不和合性

  Forms explosive mixture with air (flash point varies). MEKP (2-Butanone peroxide) 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.

• 廃棄物の処理

  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
