Acetylsalicylic Acid

Acetylsalicylic acid (ASA) produces bronchospasm in 0 3% of normal adults and in from 4% to 20% of asthmatic patients The ASA triad is a syndrome characterized by asthma nasal polyposis and drug sensitivity Furthermore other nonsteroidal anti-inflammatory agents (NSAIDs) can produce a similar reaction and should be avoided in aspirin-sensitive patients The first manifestation of the

The melting point of acetylsalicylic acid is between 128

The melting point of acetylsalicylic acid is between 128-137 C The melting point obtained for this reaction is around 100-107 C This shows that the final compound was not completely pure In other words it was compromised by other components during the experiment One possible component is the presence of water which might affect the melting point of the final product

Chemical of the Week

In poorly heated laboratories the acid was oftentimes found frozen inside its container because its freezing point is only slightly below room temperature at 16 7C The term glacial (ice-like) came to be applied to the pure acid in either its solid or liquid state Glacial acetic acid boils at 118C and has a density of 1 049 g/mL at 25C It is flammable with a flash point of 39C
