三氧化铬

Chromium oxide

三氧化铬

Chromium oxide (chemical formula: CrO3), usually dark red orthorhombic crystals, soluble in water, alcohol, sulfuric acid and ether, but insoluble in acetone, easy deliquescence. Dissolved in water to produce chromic acid. With strong oxidizing properties. Chromium oxide, sulfuric acid and acetone are used to oxidize alcohols to carboxylic acids or ketones (Jones oxidation reactions). Chromium oxide can be precipitated by the reaction of sodium dichromate and concentrated sulfuric acid, so it has long been called chromic acid. It decomposes above 197 ° C, gradually losing oxygen, the intermediate product has black chromium dioxide, the final product for the chromium oxide. It can form an adduct of the formula CrO3 · 2L with many organic compounds such as pyridine. ... 三氧化铬(化学式:CrO3),通常呈暗红色斜方结晶,可溶于水、醇、硫酸和乙醚,但不溶于丙酮,容易潮解。溶于水生成铬酸。具强氧化性。三氧化铬、硫酸和丙酮用于将醇氧化为羧酸或酮(Jones氧化反应)。 三氧化铬可以通过重铬酸钠和浓硫酸反应沉淀出来,因此曾长期被称作铬酸。它于197 °C以上分解,逐渐失去氧,中间产物有黑色的二氧化铬,最终产物为三氧化二铬。 它可以与很多有机化合物(如吡啶)形成通式为CrO3·2L的加合物。...
