ジメチル亜鉛 化学特性,用途語,生産方法
解説
Zn(CH3)2(95.48).ジメチル亜鉛は,メチル亜鉛ともいう.ハロゲン化メチル亜鉛CH3ZnXの熱分解により合成される.無色の液体.融点-42.2 ℃,沸点46 ℃.d10.541.386.エーテルに可溶.水,アルコール類と反応してメタンを発生する.空気中では徐々に酸化され,メチル亜鉛メトキシドCH3ZnOCH3を生じる.エーテル中でメチルリチウムと反応してLi2(CH3)4Zn(C2H5)2Oの組成を有する安定な化合物が得られる.Zn(CH3)2は,ほかの金属のメチル化剤として用いられたり,アニオン重合の開始剤あるいはチーグラー型触媒の一成分として用いられる.森北出版「化学辞典(第2版)

化学的特性
Clear colorless liquid
使用
Dimethylzinc is pharmaceutical compound comprising Hemiasterlin derivatives and its antibody conjugate for treatment of cancer.
一般的な説明
Mobile liquid, with peculiar garlic odor.
空気と水の反応
Highly flammable. Ignites in air and burns with a blue flame giving off a peculiar garlicky odor. Explodes in oxygen or ozone. Reacts violently with water to generate methane [Merck, 11th ed., 1989; Brauer(1965)]. Very slow oxidation with traces of air to give methylzinc methylate.
反応プロフィール
DIMETHYLZINC is very reactive, acts as a strong reducing agent. Combines with acids, with alcohols (methanol, ethanol), and 2-2-dichloropropane as well as with water with explosive violence. When heated to decomposition emits toxic fumes of zinc oxide [Bretherick, 5th ed., 1995, p. 354]. Oxidants may yield peroxide formation, which is explosive.
健康ハザード
Inhalation of mist or vapor causes immediate irritation of upper respiratory tract. Excessive or prolonged inhalation of fumes from ignition or decomposition may cause ``metal fume fever'' (sore throat, headache, fever, chills, nausea, vomiting, muscular aches, perspiration, constricting sensation in lungs, weakness, sometimes prostration). Symptoms usually last 12-24 hrs. Eyes are immediately and severely irritated by liquid, vapor, or dilute solutions. If not removed by thorough flushing with water, chemical may permanently damage cornea. Skin will undergo thermal and acid burns when chemical reacts with moisture in skin. Unless washed quickly, skin may be scarred. Treat dilute solutions with same precautions as concentrated liquid. Ingestion, while unlikely, would cause immediate burns at site of contact. Nausea, vomiting, cramps, and diarrhea may follow. Tissues may ulcerate if not treated.
