Preparing benzoic acid from benzylalcohol
Planning (a)
Problem
The aim of this experiment is to synthesize benzioc acid, with the highest possible yield, by oxidizing benzylalcohol.
Hypothesis
We expect the percentage yield to be about 50% due to several processes such as cooling and filtering.
Possible Variables
- Time
- Temperature (of water)
- Filter
Planning (b)
Apparatus/ Materials
- Round bottomed flask under reflux
- benzylalcohol
- HCl
- Na2O4
- Büchner funnel
- beakers
- sodium carbonate
Procedure
The benzioc acid is synthesized by heating benzylalcohol in a round bottomed flask under reflux. In addition to that, we use Na2O4 as a oxidizing agent. After that, we use HCl to precipitate it. After the some time, we filter it through a Büchner funnel before it is recrystallized and filtered again. The mass was recorded as it was dry.
