I am doing a report on the synthesis of Dulcin from Phenetidine, Potassium Cyanate, and Acetic Acid. Potassium Cyanate reacts with Acetic Acid to form isocyanic acid, which then reacts with Phenetidine to produce Dulcin.
1) Why is it important to add acetic acid to the reaction mixture? What would happen if you forgot to add it?
2) Is it necessary to produce isocyanic acid in the reaction flask, or could it be preformed and added to the reaction flask later?

Write a mechanism of the synthesis diisobutylene from tert-butyl alcohol with the use of elimination reaction. The following is the procedure of how it was done in the orgo lab: First of all, with the use of graduated cylinder 7mL of water was measured and then transferred in a 50mL round bottom flask. To the round bottom flask, it was added 7mL of sulfuric acid. The mixture was then cooled until the temperature got below 50 °C. In order to...

QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

Hello everyone! I am sorry in advance for so many questions. There is experimental procedure for benzocaine synthesis from p-aminobenzoic acid: 12 ml of ethanol and 0.9 g of p-aminobenzoic acid was added and stirred until dissolving after 1 ml of conc. H2SO4 was added. Then it was heated under reflux for 40 minutes and cooled, next the mixture was transferred into 250 ml flask with 30 g of ice and 30 ml of water and 10 ml of 10%...
