The Acetanilide, with the CAS registry number 103-84-4 and EINECS registry number 203-150-7, has the systematic name of N-phenylacetamide, and it is also known as Antifebrin. It is an odourless solid chemical of leaf or flake-like appearance, and the pure crystals are plate shaped and colorless to white. It is slightly soluble in water, and stable under most conditions. The molecular formula of this chemical is C8H9NO.
The physical properties of Acetanilide are as followings: (1)ACD/LogP: 1.08; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.08; (4)ACD/LogD (pH 7.4): 1.08; (5)ACD/BCF (pH 5.5): 3.91; (6)ACD/BCF (pH 7.4): 3.91; (7)ACD/KOC (pH 5.5): 92.44; (8)ACD/KOC (pH 7.4): 92.44; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 1; (12)Polar Surface Area: 20.31 Å2; (13)Index of Refraction: 1.575; (14)Molar Refractivity: 40.52 cm3; (15)Molar Volume: 122.5 cm3; (16)Polarizability: 16.06×10-24cm3; (17)Surface Tension: 41.5 dyne/cm; (18)Density: 1.103 g/cm3; (19)Flash Point: 173.9 °C; (20)Enthalpy of Vaporization: 54.49 kJ/mol; (21)Boiling Point: 304.5 °C at 760 mmHg; (22)Vapour Pressure: 0.000871 mmHg at 25°C.
Preparation of Acetanilide: It can be prepared by reacting acetic anhydride with aniline:
C6H5NH2 + (CH3CO)2O → C6H5NHCOCH3 + CH3COOH
Applictions of Acetanilide: It is often used as an inhibitor in hydrogen peroxide to stabilize cellulose ester varnishes. It is also used in the intermediation in rubber accelerator synthesis, dyes and dye intermediate synthesis, camphor synthesis and so on. It is used for the production of 4-acetamidobenzenesulfonyl chloride, a key intermediate for the manufacture of the sulfa drugs as well. What's more, it is also a precursor in the synthesis of penicillin and other pharmaceuticals.
You should be cautious while dealing with this chemical. It irritates to eyes, respiratory system and skin, and it is also harmful if swallowed. Therefore, you had better take the following instructions: Do not breathe dust; Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice.
