Monsanto process

<p>The Monsanto process is an industrial method for the manufacture of <a href="/facts/Acetic_acid/uyBKA2Pd">acetic acid</a> by catalytic <a href="/facts/Carbonylation/Jq8jghNR">carbonylation</a> of <a href="/facts/Methanol/EIfpoNCg">methanol</a>.  The Monsanto process has largely been supplanted by the <a href="/facts/Cativa_process/h829bEle">Cativa process</a>, a similar <a href="/facts/Iridium/TFQutoj1">iridium</a>-based process developed by <a href="/facts/BP/awvwSJ3x">BP Chemicals Ltd</a>, which is more economical and environmentally friendly.
</p><p>This process operates at a <a href="/facts/Pressure/eyc37GRG">pressure</a> of 30–60 <a href="/facts/Atmosphere_(unit)/aTbYALII">atm</a> and a <a href="/facts/Temperature/QyGe4gmj">temperature</a> of 150–200 °C and gives a selectivity greater than 99%. It was developed in 1960 by the German chemical company <a href="/facts/BASF/cdtGr0TK">BASF</a> and improved by the <a href="/facts/Monsanto_Company/6rVAaIXB">Monsanto Company</a> in 1966, which introduced a new catalyst system.
