Industrial-grade anhydrous ethanol: Industrial-grade anhydrous ethanol typically has a purity of 99.5% or higher and is mainly used in chemical synthesis and fuel additives. Its price is relatively low, making it suitable for large-scale industrial production. It should be noted that industrial-grade products may contain trace impurities and require purification treatment according to specific process requirements before use.
Pharmaceutical-grade anhydrous ethanol: Pharmaceutical-grade anhydrous ethanol has even higher purity (generally ≥99.8%), meets pharmacopoeia standards, and is commonly used in pharmaceutical preparations and disinfection. It offers higher safety and purity, effectively preventing impurities from affecting drug quality. For example, pharmaceutical-grade anhydrous ethanol is a commonly used solvent in injectable drug production.
Food-grade anhydrous ethanol: Food-grade anhydrous ethanol strictly adheres to food contact material safety standards and can be used for solvent extraction and flavoring in food processing. Its production process has extremely high hygiene requirements to ensure that residual levels meet food additive usage standards. In the food industry, it can be used to manufacture edible alcohol, flavorings, and other products.
Electronic-grade anhydrous ethanol: Electronic-grade anhydrous ethanol boasts a purity of over 99.99% and extremely low impurity content, primarily used in precision industries such as semiconductor and electronic component cleaning. Its control over contaminants such as moisture and metal ions is extremely stringent, effectively preventing damage to electronic devices.
Fuel-grade anhydrous ethanol: Fuel-grade anhydrous ethanol is often blended with gasoline to produce ethanol gasoline, used as a clean energy source. It increases the octane rating of fuel and reduces emissions. Currently, many countries worldwide have promoted the use of ethanol gasoline to reduce dependence on fossil fuels.
