Trimethylacetonitrile is a colorless and transparent liquid with high polarity and solubility. Its dielectric constant varies with temperature and frequency. At room temperature, the dielectric constant of trimethylacetonitrile is approximately 37.5, which gradually decreases at high temperatures. The high dielectric constant of trimethylacetonitrile makes it widely used in the field of electrochemistry. For example, in electrochemical reactions, trimethylacetonitrile can be used as a solvent and electrolyte to improve the efficiency and rate of the reaction. At the same time, trimethylacetonitrile can also be used as a dielectric for capacitors, to store charge and energy.??? ??
CLEAR COLOURLESS LIQUID??
Trimethylacetonitrile used as a solvent and as a labile ligand in coordination chemistry. It is also used as an intermediate in organic synthesis. It is used in the presence of titanium(II) chloride and zinc to undergoes reductive coupling reaction of aromatic and aliphatic ketones including acyclic aliphatic ketones to give the corresponding pinacols.?? ??
Trimethylacetonitrile can be used:As an intermediate compound, it is a product of benzopyrimidine in the preparation of 6-substituted phenanthridines[1].
As a laboratory research material for the thermodynamic correlation index determination of chemistry, spectroscopic determination and reduction reaction studies with Grignard reagents[2-4].
Purification Methods
Purify it by a two-stage vacuum distillation and de-gas by the freeze-pump-thaw technique. Store it under vacuum at 0o. TOXIC, use an efficient fume hood. [Beilstein 2 IV 875.]?????????? ?? ?? ? ???
