<h3>Overview</h3>
<p><strong>Tert-butyl methyl ether</strong> (CAS <strong>1634-04-4</strong>, MTBE) is a colorless liquid solvent produced via acid-catalyzed reaction of isobutylene and methanol. Molecular formula: <strong>C5H12O</strong>. It serves as a high-octane fuel oxygenate and critical industrial extraction agent.</p>
<h3>Application</h3>
<ul>
<li>Petroleum refining: Enhancing gasoline octane ratings and reducing emissions.</li>
<li>Chemical synthesis: Solvent for polyisobutylene and synthetic rubber production.</li>
<li>Laboratory use: Extraction medium for polar organic compounds.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly store in cool, ventilated areas away from ignition sources due to high flammability. Avoid inhalation and skin contact; use appropriate PPE including respirators and chemical-resistant gloves. Regulatory restrictions apply in water-sensitive zones due to groundwater contamination risks.</p>
