Day 125. Remember when you used to do equilibrium demonstrations?

The equilibrium between cobalt species Co(H2O)62+ and CoCl42− can be disturbed by changing the chloride ion concentration or by changing the temperature (in this case).

Making some fresh, absolute tetrahydrofuran (THF) with benzophenone and sodium. The diphenylketyl-sodium has this beautiful deep blue color what only appears if no water, oxygen, CO2 or anything bad is left in the solution. 

This treatment is used for removing traces of water from the solution.

The benzophenone ketyl is an anion radical that contains a group Ph2C−O•. It is the product of the 1-electron reduction of a ketone.

Just a deep red reaction mixture that slowly separates from the water phase in a separating funnel. 

In this case a dichloromethane solution was washed with brine and due the similar density of the saturated brine to the dichloromethane (1.33 g/cm3) these type of extractions are hard to separate. If this happens a mild dilution of the brine, or the organic phase could help. If the density of the two solution differs a bit, rapid phase separation will happen.

Screening different reaction conditions using a catalystin a special reaction. Each vial contains a different amount/conentration of reactant or another solvent.

Often to find the perfect conditions for an organic chemical transformation is a long and complex task. It could take dozens reactions and LOT time to get good result. It is a hard thing to prepare a compound, another hard task is to prepare it in a pure form and a harder quest is to make it on an efficient way.
