Heat
Is used to speed up the reaction (since organic chemistry tend to have slow reactions)
Reflux Condenser
Is connected to a water source (cool down vapors) to provide an environment of lower temperature so when the chemical is boiled it will not evaporate and return to its original liquid state.
Salicylic Acid
Methanol
SYNTHESIS OF METHYL SALICYLATE
Two Chemicals That Reacted:
Salicylic Acid
Methanol
Sulfuric Acid
Chemical involved during the synthesis of Methyl Salicylate:
Sulfuric Acid
SYNTHESIS OF METHYL SALICYLATE
Is only used as catalyst and provides an ideal (acidic) environment for the reaction to occur.
Methyl Salicylate
Water
Salicylic acid reacted with methanol under an acidic environment to form?
Sodium Bicarbonate
What is added to the round bottom flask with methyl salicylate and water that is poured into the beaker?
React with Unreacted Salicylic Acid
What is the purpose of the addition of NaHCO3 into the solution (methyl salicylate and water)?
Sodium Salicylate
NaHCO3 will react with the unreacted salicylic acid and turns into?
Salicylic Acid
Sodium salicylate is the ionized (water soluble) form of?
Methyl Salicylate
Sodium Salicylate
In the beaker we only have two major compounds :
To isolate methyl salicylate because it is unionized (water- insoluble).
Why do we need to make the solution water soluble?
Hexane
In our separatory funnel we have a solvent in the form of? (non-polar/ water-insoluble)
True
TRUE OR FALSE
Salicylic acid is soluble in hexane.
False
TRUE OR FALSE
Methyl salicylate is not soluble in hexane.
Dry Powder
Solid Form of Methyl Salicylate
Yellowish or Reddish Liquid
Liquid Form of Methyl Salicylate
Wintergreen (Effervescent)
What is the odor of Methyl Salicylate?
C8H8O3
Molecular Formula of Methyl Salicylate
152.15 g/mol
Molecular Weight of Methyl Salicylate
220-224 °C
Boiling Point of Methyl Salicylate
1.18
Specific Gravity of Methyl Salicylate
Ferric Chloride Test
It is the test for phenolic compounds.
Violet Coloration
Positive Result:
Orange/ Yellowish
Negative Result:
Gaultheria procumbens
Methyl Salicylate is the Active Constituent of?
Counterirritant
Rubefacient
Uses of Methyl Salicylate (In Liniments)
Manipulate the pH of Urine (Sodium Bicarbonate)
Ingestion in large amounts will lead to salicylate poisoning.
