비스 (클로로메틸) 케톤 C화학적 특성, 용도, 생산
화학적 성질
White or colorless crystals
용도
1,3-Dichloroacetone was used as acceptor substrate in the cross-aldol reaction with donor substrates such as acetone, cyclopentanone and cyclohexanon
일반 설명
A crystalline solid. Denser than water and insoluble in water. Inhalation of dust or powder may cause adverse health reactions.
공기와 물의 반응
Insoluble in water.
반응 프로필
A halogenated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
건강위험
1,3-Dichloroacetone may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution.
화재위험
When heated to decomposition, 1,3-Dichloroacetone emits highly toxic fumes of chlorides. 1,3-Dichloroacetone may burn but does not ignite readily. Container may explode in heat of fire.
Safety Profile
Poison by inhalation. Mutationdata reported. A systemic irritant by ingestion andinhalation routes. Dangerous; whenheated to decomposition it emits highly toxic fumes ofCl-.
잠재적 노출
Formerly extensively used in textiles
(especially polyester fabrics) and still employed in polyurethane
foams, textile backcoating and adhesives.

Purification Methods
Crystallise it from CCl4, CHCl3 or *benzene and/or distil under vacuum [Conant & Quayle Org Synth Coll Vol I 211 1941, Hall & Sirel J Am Chem Soc 74 836 1952]. It is dimorphic [Daasch & Kagarise J Am Chem Soc 77 6156 1955]. The oxime has m 130-131o, b 106o/25mm [Arzneimittel-Forsch 8 638 1958]. [Beilstein 1 IV 3219.]
