a)Determine the limiting reagent in aspirin synthesis given 3g of salicylic acid. b)Based on your answer, calculate the maximum weight of aspirin that you could prepare. c)As is true for most "organic" reactions the synthesis you do here is an equilibrium reaction. What steps could you take to improve the yield. d)The solubility of aspirin in ethanol is approximately 40g/100 mL at room temperature. If you had a 100% yield, how many milliliters of ethanol would you need to dissolve your product for the recrystallization step?
Hi, thanks for your question. We will be glad to answer you but it is missing an important data in this problem i.e. mass of acetic anhydre. However in order to help you we will give you an example in which acetic anhydre is the limiting reagent.
c)In order to improve the yield of reaction: protonation of acetic anhydre is important
d)
40g ------ 100mL
3.9095 g ----X
X = 3.9095 g/40g x 100 = 9.7738 mL ethanol
