Phenacetin, its cas register number is 62-44-2. It also can be called Aceto-p-phenetidin. Phenacetin is a white crystalline powder with the chemical composition C10H13NO2. Phenacetin is an analgesic, once widely used; its use has declined because of its adverse effects. In addition to its pain-reducing properties, it also has been used as a fever-reducer, a treatment for rheumatoid arthritis and a treatment for intercostal neuralgia, a rare disorder that causes pain in the nerves around the ribs.
Physical properties about Phenacetin are: (1)ACD/LogP: 1.655; (2)ACD/LogD (pH 5.5): 1.66; (3)ACD/LogD (pH 7.4): 1.66; (4)ACD/BCF (pH 5.5): 10.67; (5)ACD/BCF (pH 7.4): 10.67; (6)ACD/KOC (pH 5.5): 189.43; (7)ACD/KOC (pH 7.4): 189.44; (8)#H bond acceptors: 3; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 3; (11)Index of Refraction: 1.549; (12)Molar Refractivity: 51.836 cm3; (13)Molar Volume: 163.025 cm3; (14)Polarizability: 20.549 10-24cm3; (15)Surface Tension: 39.0260009765625 dyne/cm; (16)Density: 1.099 g/cm3; (17)Flash Point: 168.531 °C; (18)Enthalpy of Vaporization: 60.016 kJ/mol; (19)Boiling Point: 355.054 °C at 760 mmHg
Preparation of Phenacetin: Phenacetin may be synthesized as an example of the Williamson ether synthesis: ethyl iodide, paracetamol, and anhydrous potassium carbonate are refluxed in 2-butanone to give the crude product, which is recrystallized from water.
When you are using this chemical, please be cautious about it as the following:
1. Avoid exposure - obtain special instruction before use;
