Question 4 (2 points) Assuming that you are starting step 3 of the Dilantin synthesis with 1
Draw the balanced chemical reaction for the condensation reaction of benzil to dilantin ( the synthesis of dilantin)
Phenytoin can be produced with ease from benzil and
Principle: Base catalyzed reaction between benzyl and urea is used for synthesis of phenytoin
The sodium salt of 5,5-diphenylhydantoin is an anticonvulsan
EXPERIMENT NO: 01 Date: Synthesis of Benzimidazole Aim: To perform synthesis of Benzimidazole Reference: with 1
-Determine the limiting reactant based on the specific amounts of reactants written in the lab manual; calculate the theoretical yield -View the IR of dilantin
75gm urea, 3
06 g
The preliminary reaction involved in the multi-step synthesis of dilantin (aka phenytoin) involves the conversion of benzaldhehyde (1) to benzoin (2)
Phenytoin, 5,5-diphenylimidazolidinedione is synthesized in two different ways
4 mL of ethanol, and 0
Then set aside for half an hour and crystal of chlorbutanol was separated out
Separate the aspirin from the reaction by-products using vacuum filtration
Report percent yield and calculation of theoretical Alpha benzilmonoxime was prepared by the reaction of benzil with hydroxylamine hydrochloride in the presence of sodiumhydroxide and ethanol
Molecular weight of benzion = 212 g/mole
2 mL of 2% Need help with the calculations for amount of benzil used in moles, isolated yield in moles, theoretical yield in grams/moles, percent yield, and overall yield?? Dilantin by multistep synthesis - Synthesis of Dilantin (Part 3) 1
I think this may be right, but I assumed all of my molar ratios were equal to 1
Molecular weight of benzil = 210 g/mole
sulfuric acid was used as the catalyst for the fast conversion of product from starting alcohol and acid

Placed 2g of benzil, 30mL of 95% ethanol in a 100mL R
What is the theoretical yield ( 100% yield) of this chalcone 6 experiment was 135°C -136°C
The synthesis of azidodiphenylacetamide 3, as described previously by Hohenlohe-Oehringen , started from 2-bromo-2,2-diphenylacetonitrile followed by an azidation reaction to yield the crucial intermediate 2-azido-2,2-diphenylacetonitrile
