                How is Maleic Anhydride Produced?<\/strong><\/h3>

                Maleic anhydride is typically produced through the oxidation of n-butene.<\/strong> The production process consists of the following steps: <\/p>

                1. Preparation<\/strong>
                  • n-Butene, oxygen, and nitrogen gases are fed into the reactor.<\/li><\/ul><\/li>
                  • Use of Catalysts<\/strong>
                    • The reaction yield is increased by adding molybdenum or vanadium-based catalysts.<\/li><\/ul><\/li>
                    • Heating<\/strong>
                      • The reactor is heated to a temperature range of 300\u2013400 \u00b0C.<\/li><\/ul><\/li>
                      • Reaction<\/strong>
                        • n-Butene reacts with oxygen to form maleic anhydride.<\/strong><\/li><\/ul><\/li>
                        • Separation and Cooling<\/strong>
                          • The resulting gas mixture is cooled and maleic anhydride is separated.<\/li><\/ul><\/li>
                          • Purification and Packaging<\/strong>
                            • The product is purified and packaged for industrial use.<\/li><\/ul><\/li><\/ol>
