The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
synthetic route:

With
NH4OH;
In
ethanol; water;
aq. ethanolic soln. of metal chloride and ligand were mixed in 1:1 moleratio, the pH of the stirred soln. was adjusted by dropwise addn. of very dil. NH4OH ethanolic soln. to just below pptn. of hydrated hydroxide or oxide for 2 h, refluxed for 6-8 h; ppt. filtered, dried in vac. over CaCl2, elem.anal.;
- Guidance literature:
-
In
ethanol;
adding ethanolic ammonia, dropwise, to an ethanolic soln. of chloride and ligand (1:1 mole ratio) until pH was just below that required for pptn. of the rare earth hydroxide, mixt. was then heated at reflux for 6-8 h; prepicitate filtrated, washed with water and ethanol and dried in vac. over CaCl2;
