What is the NMR spectrum of acetic acid?
This gas was acetic acid; an end product in the aspirin synthesis reaction, thus the NMR spectrum of acetic acid was analyzed. It is known from the NMR spectrum of acetone, which is a reference compound with only one type of hydrogen (that belonging to CH 3 ), that the peak at 2 PPM in the acetic acid spectrum pertains to CH 3 (table 2.3).
Is acetic anhydride an anhydrous reagent?
Thus, an anhydrous ( without water ) reagent could lead to better yields of product. This reagent is acetic anhydride. Acetic anhydride is a clear, colorless, mobile (free-flowing) liquid with a sharp odor similar to that of acetic acid. It hydrolyzes in water to yield acetic acid.
What is the melting point of acetic anhydride?
Acetic anhydride melts at –73°C, boils at 139°C, and has a density of 1.080 g/mL at 15°C. It is flammable with a flash point of 54°C. This compound is readily combustible and represents a fire hazard. As the name indicates, an acid anhydride is a compound that is related to an acid by the loss of water.
