Acetic anhydride is also used to make acetic acid, which is a widely used compound. This process involves combining the anhydride with water, which then breaks down into acetonic and formic acids. The acetonic acid undergoes hydrolysis with ethanol to produce ethanol and acetic acid, while formic acid on its own can be produced by reacting it with hydrogen peroxide. Acetone also products from this reaction but it can be removed through purification if needed.
Acetic anhydride also has various uses in semiconductor production. It is used as a catalyst to help produce gallium arsenide. The process involves combining the anhydride with silicon tetrachloride and aluminum tribromide to form aluminum chloride, which is then oxidized further to produce aluminum oxide and silicon dioxide. The oxide reacts with arsenic trioxide and trichlorosilane to form gallium, which reacts further with phosphorus pentoxide to make a phosphor containing arsenic-based phosphor crystals. This compound can be used in manufacturing light emitting diodes or liquid crystal displays through a variety of processes involving different types of catalysts and various solvents.
Acetic anhydride is also used to help form dimethyl acetylenediacetate from butadiene. This reaction involves adding acetic acid to hydrogen peroxide to produce the catalyst needed for the reaction, then separating and purifying the traces of by-product formed in the process. This by-product helps produce other products such as ethylene glycol and acetone.
Acetic anhydride is also used in manufacturing polyolefin lubricants, which are commonly used in various industrial applications that involve oil refining or heavy duty machinery. This process starts with producing a by-product called cyclohexene oxide, which is then reacted with ethylene glycol to produce 1-hexene.
Acetic anhydride also has a variety of uses in manufacturing various products and materials, apart from the ones already mentioned above. It can be used as a solvent to dissolve other compounds or break down an existing compound into simpler forms. For instance, it can be used to make vinyl acetate monomer, which is a compound that is used extensively in the manufacture of acrylic fibers and certain types of plastic. Acetone is also produced as a by-product in this process.
In conclusions, acetic anhydride (acetic anhydride molar mass) common uses have far reaching implications for chemical industry. It can be used as a chemical reactant or a catalyst in the chemical process of producing various commodities and products, including but not limited to ethylene glycol, vinyl acetate polymer, aspirin and polyurethane insulation material. It is also used as an active ingredient in the chemical processes of manufacturing many other products such as insulin, steroids and antibiotics.
