Oxindole (2-indolone) is an aromatic heterocyclic organic compound with the formula C 6 H 4 CHC(O)NH.It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring.
Indole-3-butyric acid (1H-indole-3-butanoic acid, IBA) is a white to light-yellow crystalline solid, with the molecular formula C 12 H 13 NO 2. It melts at 125°C in atmospheric pressure and decomposes before boiling. IBA is a plant hormone in the auxin family and is an ingredient in many commercial horticultural plant rooting products.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
The triazole is unstable and at elevated temperatures, nitrogen is released and the carbazole is formed. [11] [12] Fluorescence of (9H-carbazol-9-yl)(2,4-dichlorophenyl) methanone. Diphenylamine derivatives, being electron rich, naturally oxidize to carbazoles when heated in air. [13] A similar reaction is the Mallory reaction:
Phenylhydrazine forms monoclinic prisms that melt to an oil around room temperature which may turn yellow to dark red upon exposure to air. [1] Phenylhydrazine is miscible with ethanol, diethyl ether, chloroform and benzene. It is sparingly soluble in water.
