&lt;/span&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Alberto Cavaliere&lt;/span&gt;&lt;span style=&quot;color: #ffffff;&quot;&gt;, nella sua Chimica in versi, preparava il lettore al capitolo sulla&lt;/span&gt; &lt;span style=&quot;color: #99ccff;&quot;&gt;distillazione del catrame&lt;/span&gt;&lt;span style=&quot;color: #ffffff;&quot;&gt;.&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: #ffffff;&quot;&gt;Nel XIX secolo, i pionieri del gas di citt&amp;agrave; si son trovati con questo scomodo sottoprodotto della distillazione del carbone e i chimici hanno trovato cosa farne, sviluppando al contempo le conoscenze in ambito scientifico con la scoperta di numerosi composti.&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Faraday&lt;/span&gt;

&lt;span style=&quot;color: #99ccff;&quot;&gt;fenolo&lt;/span&gt;&lt;span style=&quot;color: #ffffff;&quot;&gt;, usato dal dottor &lt;/span&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Lister&lt;/span&gt;&lt;span style=&quot;color: #ffffff;&quot;&gt;, medico e chirurgo, come antisettico in soluzione acquosa (il famoso&lt;/span&gt;
