Tetraethyl orthocarbonate Chemical Properties,Usage,Production
Chemical Properties
clear colorless liquid
Uses
Tetraethyl Orthocarbonate is used in the synthesis of chemokine receptor-5 inhibitors against HIV-1, benzobisoxazoles and in the preparation of organic semiconductors. It is also employed in the synthesis of 2,7-dimethylene-1,4,6,9-tetraoxaspiro[4,4]nonane and in the synthesis of cross linked poly(orthocarbonate)s used as organic solvent absorbent.
Purification Methods
Likely impurities are hydrolysis products. Shake the orthocarbonate with brine (saturated NaCl, dilute with a little Et2O if amount of material is small) and dry (MgSO4). The organic layer is filtered off and evaporated, and the residue is distilled through a helices packed fractionating column with a total reflux partial take-off head. All distillations can be done at atmospheric pressure in an inert atmosphere (e.g. N2).
