IPA Used in the Electronic Industry
IPA is used as a high-purity solvent for surface degreasing and dehydration cleaning of semiconductors, integrated circuits, and PCBs.
Isopropanol Used in the Chemical Manufacturing
Isopropanol is mainly used in the production of bulk and fine chemicals such as acetone, hydrogen peroxide, methyl isobutyl ketone (MIBK), and isopropylamine.
Propanol Used in the Coating Industry
Propanol is an excellent solvent for nitrocellulose, rubber, and resins. It is used to adjust viscosity and accelerate drying, and is widely applied in the production of alcohol-soluble inks and environmentally friendly coatings.
1-Methylethanol Used in the Pharmaceutical Industry
- Medical Disinfectant： 1-Methylethanol at a concentration of 70%–75% exhibits the best bactericidal efficacy and is commonly used for skin disinfection (e.g., pre-injection) and surface disinfection of medical instruments (e.g., thermometers, surgical tools).
- Pharmaceutical Intermediates: It is used in the synthesis of certain drugs (e.g., antibiotics, vitamins) or as a solvent in production processes.
1-Methylethyl Alcohol Used in the Cosmetic Industry
1-Methylethyl alcohol is used as a solvent or carrier in cosmetics, perfumes, hair sprays, and hand sanitizers, helping ingredients disperse evenly and dry quickly.
2-Hydroxypropane Used in the Energy Industry
Isopropyl alcohol can be added in small amounts to gasoline as a dehydrating agent or blending component to improve combustion performance.
2-Propanol Used in the Laboratory
In biological, chemical, and pharmaceutical laboratories, 2-propanol is widely used as a solvent, reaction medium, or cleaning agent due to its excellent chemical properties, facilitating smooth experiments and accurate results.
