<h3>Overview</h3>
<p>Tetraethylene glycol dimethyl ether, also known as Tetraglyme, is a high-boiling polar aprotic solvent synthesized via the polyetherification of ethylene oxide with methanol. Its molecular formula is <strong>C<sub>10</sub>H<sub>22</sub>O<sub>5</sub></strong> and CAS number is <strong>112-49-2</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>Lithium-ion Batteries:</strong> Serves as an electrolyte component for high-voltage stability.</li>
<li><strong>Organic Synthesis:</strong> Acts as a reaction medium for nucleophilic substitutions and metal-catalyzed reactions.</li>
<li><strong>Extraction Processes:</strong> Utilized in liquid-liquid extraction for separating aromatic hydrocarbons from aliphatic streams.</li>
</ul>
<h3>Precautions</h3>
<p>Store in tightly sealed containers under inert atmosphere to prevent peroxide formation. Avoid contact with strong oxidizers. Use appropriate PPE including chemical-resistant gloves and eye protection during handling due to potential irritation risks.</p>
