Can someone please help me do Separation Scheme:
Its to show in the form of a simple flowchart, how a reaction product is isolated (separated) and purified from the mixture of product, by-products, and unreacted starting materials present at the end of a synthesis reaction. The connecting arrows usually include a solvent or reagent that has been added to the product mixture at that point, and most importantly, some method of separating components of the mixture is indicated.
- Weight of the vial with 5mL of tert-pentyl alcohol = 14.277g
- Weight of the empty vial (after alcohol was poured into separatory funnel) = 10.247g
- Alcohol was poured into a 125ml separatory funnel
- 12ml of concentrated Hydrochloric acid was added to separatory funnel with the alcohol
- Added 10mL of water & washed, swirled, shooke the organic layer to excess acid.
- Tert-pentyl alcohol is the Alkyl Halide (organic layer in separatory funnel)
- Washed organic layer in separatory funnel with 10mL of water to remove any residual base
- 10mL of 5% Aqueous Sodium Bicarbonate was added to organic layer.
- Primary gas that's vented is Carbon dioxide, formed by reaction of basic Sodium Bicarbonate with the excess Hydrochloric acid in the aqueous solution:
HCl + Na+HCO3- --> Na+Cl- + H2CO3
H2CO3 ⇌ H2O + CO2
10.Dried the crude tert-pentyl chloride over with Anhydrous Sodium Sulfate
11.Weight of empty vial (before poured in crude tert-Pentyl Chloride) = 10.217g
12.Weight of vial with tert-Pentyl Chloride = 14.246g
13.SIMPLE DISTILLATION WAS NOT PERFORMED!
