P-TOLYLUREA C화학적 특성, 용도, 생산
화학적 성질
beige crystalline powder일반 설명
Colorless crystals.공기와 물의 반응
Slightly soluble in hot water.반응 프로필
P-TOLYLUREA is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).건강위험
ACUTE/CHRONIC HAZARDS: Slightly toxic. Hazardous decomposition products.Purification Methods
Crystallise the urea from H2O (m 186o), EtOH/water (1:1) or aqueous AcOH (m 184o). [Beilstein 12 H 941, 12 I 425, 12 II 512, 12 III 2084, 12 IV 1923.]P-TOLYLUREA 준비 용품 및 원자재
