イソ酪酸 無水物 化学特性,用途語,生産方法
外観
無色~わずかにうすい黄色, 澄明の液体
溶解性
エタノールに極めて溶けやすく、温水に分解して溶ける。水によって徐々に分解してイソ酪酸を生じる。
用途
有機合成原料。
用途
医薬品,香料,可塑剤などの合成原料に用いられ,過酸化物として重合触媒に用いられる.(溶剤ポケットブック (1994))
化学的特性
clear colorless liquid
使用
Isobutyric anhydride was used in the synthesis of 4-
O-isobutyryl derivative via reaction with octyl β-D-glucopyranoside in the presence of C
2-symmetric chiral 4-pyrrolidinopyridine as a catalyst.
定義
ChEBI: An acyclic carboxylic anhydride of isobutyric acid. Metabolite observed in cancer metabolism.
製造方法
Isobutyric anhydride is prepared from iso-Butyryl chloride and Sodium acetate, or: from iso-Butyryl chloride and Butyric acid with a catalyst.
一般的な説明
A colorless liquid. Flash point 139°F. Burns skin and eyes. Vapors are heavier than air.
空気と水の反応
Flammable. Reacts exothermically with water or moisture-containing materials to form isobutyric acid.
反応プロフィール
Isobutyric anhydride reacts exothermically with water. The reactions are sometimes slow, but can become violent when local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with a cids, strong oxidizing agents, alcohols, amines, and bases.
危険性
Strong irritant to tissue.
健康ハザード
May cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
火災危険
Flammable/combustible material. May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
