Keep away from fire and heat sources. Smoking is prohibited in the workplace. Use explosion-proof ventilation system and equipment. Avoid producing dust. Avoid contact with oxidants, reducing agents and acids. Careful handling to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may contain harmful residues.
Storage Notes: Store in a cool, dry and well ventilated warehouse. Keep away from fire and heat. Keep the container sealed. It should be stored separately from oxidants, reducing agents, acids and edible chemicals. Equipped with corresponding types and quantities of fire fighting equipment. Storage areas should be equipped with appropriate materials to prevent leakage. The warranty period is three months from the date of factory release.
At present, the production process of industrial uphill maleic anhydride can be divided into benzene oxidation method, n-butane oxidation method, C4 olefin method and by-product method of benzoic anhydride. Including benzene oxidation is the most widely used method, but due to the limited resources of benzene, the production of maleic anhydride from C4 olefins and n-butane, especially in countries rich in natural gas and oil field associated gas, there are a large number of n-butane resources, so in recent years, the production of maleic anhydride by butane oxidation has developed rapidly. Shandong directly dominates the production of maleic anhydride, and its production capacity accounts for about 80% of the world's total production of maleic anhydride.
