Quatre anys més tard, Mansfield va començar la primera producció a escala industrial de benzè, basat en el mètode del quitrà d'hulla. A poc a poc entre els químics es va desenvolupar la sensació que una sèrie de productes relacionats amb el benzè representaven una família de substàncies químiques. El 1855 August Wilhelm Hofmann va utilitzar la paraula "<a href="/wiki/Aromaticitat" title="Aromaticitat">aromaticitat</a>" per designar aquesta relació famíliar, degut a la propietat característica de molts dels seus membres de tindre una forta olor. </p> <div class="mw-heading mw-heading2"><h2 id="Producció"><span id="Producci.C3.B3"></span>Producció</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Benz%C3%A8&action=edit&section=2" title="Modifica la secció: Producció"><span>modifica</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Es poden produir traces de benzè en la combustió incompleta de materials rics en carboni.

No obstant això, en la dècada de 1950, l'augment de la demanda per al benzè, especialment de la indústria del plàstic cada vegada més gran, va fer necessària la producció de benzè a partir del petroli. Avui en dia, la major part del benzè prové de la indústria petroquímica, amb només una petita fracció que es produeixen a partir del carbó. </p><p>Quatre processos químics contribueixen a la producció industrial del benzè : <a href="/wiki/Reformat_catal%C3%ADtic" title="Reformat catalític">reformat catalític</a>, hidrodealquilació de toluè, desproporció del toluè, i <a href="/wiki/Craqueig" title="Craqueig">craqueig</a> al vapor.

En aquestes condicions, els hidrocarburs <a href="/wiki/Hidrocarbur_alif%C3%A0tic" title="Hidrocarbur alifàtic">alifàtics</a> formen anells i perden hidrogen transformant-se en hidrocarburs aromàtics. Els productes aromàtics de la reacció se separen de la mescla de reacció (o reformat) mitjançant l'extracció amb una sèrie de solvents, com el <a href="/w/index.php?title=Dietilenglicol&action=edit&redlink=1" class="new" title="Dietilenglicol (encara no existeix)">dietilenglicol</a> o el <a href="/w/index.php?title=Sulfol%C3%A0&action=edit&redlink=1" class="new" title="Sulfolà (encara no existeix)">sulfolà</a>, i el benzè se separa dels altres compostos aromàtics de la destil·lació.

Tot i això, el toluè té un petit moment dipolar (aproximadament 0,4 D) amb la càrrega negativa sobre el nucli i la positiva sobre el grup metil.
