A #1.961*g# mass of #"salicylic acid"#, #C_6H_4(CO_2H)(OH)# is treated with excess acetic acid. How much #"ASA, i.e. aspirin"#, i.e. #"1,2-C"_6"H"_4"CO"_2"H(O"_2"CCH"_3")"# could be prepared?
First, we need to propose a stoichiometric equation that represents aspirin synthesis:
And thus we see the production of ASA is a 1:1 reaction between salicylic acid and acetic acid. What sort of reaction is this?
Given this molar quantity, and the stoichiometric equation, AT MOST we can make
Industrially, aspirin synthesis is conducted on a huge scale. Why? Because it is one of the most powerful, useful, and benign drugs known, and in recent years it has been prescribed widely as a blood-thinning agent.
