用途
有機合成原料。
化学的特性
white crystalline powder
一般的な説明
White crystalline solid. Noncombustible, but decomposes with heating.
空気と水の反応
Slightly soluble in water, soluble in hot water. Hydrolysis occurs rapidly with strong acid/base media.
反応プロフィール
N-ACETYLTHIOUREA is incompatible with strong oxidizing agents, strong acids and strong bases. Decomposes when heated to give toxic oxides of sulfur and nitrogen.
健康ハザード
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
火災危険
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
職業ばく露
Studied as possible rodenticide; used in organic synthesis.
輸送方法
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
純化方法
Recrystallise the thiourea from AcOH; the solid is washed with Et2O and dried in air then at 100o. [Zahradnik Collect Czech Chem Commun 24 3678 1959, Beilstein 3 IV 354.]
不和合性
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
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 with EPA regulations governing storage, transportation, treatment, and waste disposal.
