Il salnitro <a href="/wiki/Ossidazione" title="Ossidazione">ossida</a> lo zolfo a anidride solforica, SO<sub>3</sub>, la quale si combina con l'acqua a dare l'acido. Joshua Ward, un farmacista <a href="/wiki/Londra" title="Londra">londinese</a>, adottò questo metodo per una produzione su grossa scala nel <a href="/wiki/1736" title="1736">1736</a>. </p><p>Nel <a href="/wiki/1746" title="1746">1746</a> a <a href="/wiki/Birmingham" title="Birmingham">Birmingham</a>, John Roebuck iniziò a produrre industrialmente l'acido solforico sfruttando lo stesso metodo, ma operando in <a href="/wiki/Processo_delle_camere_di_piombo" title="Processo delle camere di piombo">camere di piombo</a>, che erano più robuste, più grandi e meno costose dei recipienti di <a href="/wiki/Vetro" title="Vetro">vetro</a> usati fino ad allora. Questo processo <i>a camere di piombo</i>, successivamente adattato e rifinito negli anni, è rimasto per quasi due secoli il processo industriale più diffuso per produrre acido solforico. </p><p>L'acido prodotto da Roebuck aveva una <a href="/wiki/Concentrazione_(chimica)" title="Concentrazione (chimica)">concentrazione</a> media del 35-40%. Successivi miglioramenti del processo apportate dal chimico francese <a href="/wiki/Joseph_Louis_Gay-Lussac" title="Joseph Louis Gay-Lussac">Joseph Louis Gay-Lussac</a> e dal chimico inglese John Glover portarono il prodotto a una concentrazione del 78%. </p><p>Tuttavia, la produzione di alcune tinture nonché alcuni processi chimici richiedevano l'uso di acido solforico più concentrato, che per tutto il <a href="/wiki/XVIII_secolo" title="XVIII secolo">XVIII secolo</a> fu ottenuto solo per distillazione dei minerali, in modo analogo a come si operava nel medio evo, arrostendo la <a href="/wiki/Pirite" title="Pirite">pirite</a> (solfuro di ferro, FeS<sub>2</sub>) in presenza di aria per trasformarla in solfato ferrico Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub> che veniva poi successivamente decomposto per riscaldamento a 480 °C in ossido ferrico e anidride solforica. L'anidride solforica veniva poi aggiunta all'acqua nelle proporzioni desiderate ottenendo acido solforico alla concentrazione desiderata. Questo processo era però particolarmente costoso e non portò mai alla produzione di grandi volumi di acido solforico concentrato. </p><p>Nel <a href="/wiki/1831" title="1831">1831</a> fu un commerciante di <a href="/wiki/Aceto" title="Aceto">aceto</a>, il britannico Peregrine Phillips, a brevettare un processo più economico per la produzione di anidride solforica e acido solforico concentrato. Nel suo processo lo zolfo o la <a href="/wiki/Pirite" title="Pirite">pirite</a> venivano bruciati a dare <a href="/wiki/Anidride_solforosa" title="Anidride solforosa">anidride solforosa</a>, SO<sub>2</sub>, che veniva successivamente trasformata con alte rese in SO<sub>3</sub> tramite reazione con l'<a href="/wiki/Ossigeno" title="Ossigeno">ossigeno</a> dell'aria passando su un <a href="/wiki/Catalizzatore" title="Catalizzatore">catalizzatore</a> di <a href="/wiki/Platino" title="Platino">platino</a> ad alta temperatura. La domanda di acido solforico concentrato all'epoca non fu tale da giustificare la realizzazione di un impianto; il primo impianto che utilizzò questo processo (detto <i>a contatto</i>) fu costruito nel <a href="/wiki/1875" title="1875">1875</a> a <a href="/wiki/Friburgo_in_Brisgovia" title="Friburgo in Brisgovia">Friburgo</a>, in <a href="/wiki/Germania" title="Germania">Germania</a>. </p><p>Nel <a href="/wiki/1915" title="1915">1915</a> la tedesca BASF sostituì il catalizzatore di platino con un più economico catalizzatore di <a href="/wiki/Vanadio" title="Vanadio">vanadio</a> pentossido, V<sub>2</sub>O<sub>5</sub>. Questo, unito alla crescita della domanda, portò alla graduale sostituzione degli impianti <i>a camera di piombo</i> con impianti <i>a contatto</i>. Nel <a href="/wiki/1930" title="1930">1930</a> questi ultimi fornivano al mercato circa un quarto della produzione totale di acido solforico; oggi ne forniscono la quasi totalità. </p> <table align="left" cellpadding="5" cellspacing="2" style="float: right;

Le bruciature causate dall'acido solforico sono potenzialmente più pericolose di ogni altro acido forte (ad esempio l'<a href="/wiki/Acido_cloridrico" title="Acido cloridrico">acido cloridrico</a>), e a questo pericolo va aggiunto quello di <a href="/wiki/Disidratazione" title="Disidratazione">disidratazione</a> della pelle per il calore di dissociazione. Il pericolo è più grande con soluzioni a concentrazione più alta, ma va ricordato che l'acido solforico per uso in laboratorio (1 <a href="/wiki/Concentrazione_di_quantit%C3%A0_di_sostanza" title="Concentrazione di quantità di sostanza">M</a>, al 10%) può provocare gravi danni se rimane a contatto con la pelle per un tempo sufficiente. Le soluzioni superiori a 1,5 M possono essere etichettate come <i>corrosive</i>, mentre quelle a meno di 0,5 M possono essere considerate <i>irritanti</i>. </p><p>L'uso dell'acido solforico fumante (oleum) non è raccomandato in ambienti frequentati, come nelle scuole, per la sua alta pericolosità. Il primo trattamento per contatti con qualunque acido è l'applicazione di <a href="/wiki/Bicarbonato_di_sodio" title="Bicarbonato di sodio">bicarbonato di sodio</a> per neutralizzare l'acido (versare subito acqua sull'acido aumenterebbe a dismisura il calore generato) poi il lavaggio dell'area interessata con grandi quantità d'acqua: questa operazione deve essere continuata per almeno 10 o 15 minuti, per raffreddare i tessuti e prevenire le ustioni dovute al calore generato. Eventuali capi di abbigliamento contaminati devono essere rimossi immediatamente. </p><p>La diluizione dell'acido solforico può essere ugualmente pericolosa: in merito può essere utile ricordare che bisognerebbe sempre versare l'acido nell'acqua, non il contrario. L'aggiunta di acqua all'acido può provocare pericolosi schizzi e la dispersione di <a href="/wiki/Aerosol" title="Aerosol">aerosol</a> di acido solforico, che inalati in quantità eccessive possono avere conseguenze negative sull'organismo. Per evitare tali incidenti è utile tenere a mente la frase <i>"non dare da bere all'acido"</i>. </p><p>A volte si utilizzano meccanismi di raffreddamento nella diluizione di grandi quantità di acido solforico, perché questo processo può portare all'ebollizione incontrollata della soluzione stessa. </p> <div class="mw-heading mw-heading3"><h3 id="Pericoli_industriali">Pericoli industriali</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Acido_solforico&veaction=edit&section=5" title="Modifica la sezione Pericoli industriali" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Acido_solforico&action=edit&section=5" title="Edit section's source code: Pericoli industriali"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Sebbene l'acido solforico non sia infiammabile, il contatto con alcuni metalli porta alla liberazione di ingenti quantità di <a href="/wiki/Idrogeno" title="Idrogeno">idrogeno</a>.
