Isopropanol: A Green Solvent and Key Material for Multiple Applications

In today's rapidly developing chemical, pharmaceutical, and electronics industries, isopropanol, as an important organic solvent and intermediate, is demonstrating irreplaceable value in multiple fields due to its unique physicochemical properties. From precision cleaning in semiconductor manufacturing to disinfection and sterilization in pharmaceutical production, and further to the green transformation of the environmental protection industry, the application scope of isopropanol is constantly expanding.

Semiconductor Manufacturing: The "Invisible Guardian" of Precision Cleaning

As chip manufacturing processes continue to shrink, the purity requirements for cleaning agents in semiconductor manufacturing are becoming increasingly stringent. Isopropanol, with its moderate polarity and rapid evaporation, has become the preferred solvent for wafer cleaning and drying. During the cleaning process, it effectively dissolves photoresist residues and organic contaminants, and removes moisture through rapid evaporation, preventing impurities from remaining on the wafer surface. This characteristic makes it a key material for ensuring chip yield.

Recently, the world's largest ultra-high purity isopropanol production base in Qianjiang, Hubei Province, is about to reach full production capacity. Once operational, this project will meet more than half of the domestic demand for advanced chip manufacturing, breaking the long-standing reliance on imports for high-end electronic chemicals. This breakthrough not only enhances the self-sufficiency and controllability of domestically produced semiconductor materials but also highlights the strategic importance of isopropanol in the electronics and information industry.

Pharmaceutical Field: A Versatile Agent for Disinfection, Sterilization, and Drug Synthesis

Isopropanol is also widely used in the pharmaceutical industry. Its 70% aqueous solution is widely used for medical device disinfection, hand cleaning, and sterilization of pharmaceutical workshops due to its significant bactericidal effect and high safety. Compared to ethanol, isopropanol has a stronger ability to kill bacteria, fungi, and viruses, and its volatility is moderate, leaving no residue after use.

Furthermore, isopropanol is an important intermediate in drug synthesis. For example, in the production of the antiviral drugs sofosbuvir and tenofovir alafenamide fumarate, isopropanol participates in the synthesis reaction as a key raw material. Its high-purity product meets pharmacopoeia standards, effectively avoiding the impact of impurities on drug quality. In wet granulation processes, isopropanol also acts as a solvent to help drug components form uniform particles, improving formulation stability.

Environmental Protection Industry: A Pioneer Solvent for Green Transformation

With increasing global environmental awareness, the environmental advantages of isopropanol are becoming increasingly prominent. Compared to traditional solvents, it emits lower volatile organic compounds (VOCs) and is easily biodegradable, meeting the pollution control policies of various countries. In industries such as coatings, inks, and daily chemicals, isopropanol is gradually replacing toxic solvents such as benzene and ketones, becoming the preferred choice for green production.

Domestic companies, represented by Shandong Shenyuan Chemical, are promoting the application of isopropanol in new energy vehicles, electronics manufacturing, and other fields by optimizing production processes to reduce energy consumption and waste gas emissions. For example, in battery production, isopropanol can be used as a cleaning agent to remove oil stains from the surface of metal parts while reducing environmental pollution. The promotion of this "green solvent" provides a feasible path for the chemical industry to achieve its "dual carbon" goals.

Industry and Daily Life: An Indispensable "Basic Raw Material"

In the industrial sector, the uses of isopropanol are even more diverse. As a solvent, isopropanol can dissolve resins, oils, and dyes, and is widely used in the production of coatings, adhesives, and cosmetics. As an extractant, it can extract organic compounds such as antibiotics from aqueous solutions. As a chemical intermediate, it is an important raw material for the production of pesticides, fragrances, and plastics.

Isopropanol is also ubiquitous in daily life. It is often added to car glass cleaners and paint care products, utilizing its cleaning and antifreeze properties. In the printing industry, it is used as a component of dampening solutions to improve print quality. Furthermore, isopropanol is a commonly used chemical reagent in laboratories for analytical testing and synthetic reactions.

Future Outlook: Technological Innovation Drives Application Expansion

With the growth of high-tech industries and environmental protection demands, the market potential of isopropanol will continue to be released. In the semiconductor field, higher purity isopropanol products will support the development of advanced processes; in the pharmaceutical industry, its demand as a disinfectant and excipient will increase with rising public health awareness; and in the environmental field, the trend of green solvents replacing traditional high-polluting products is irreversible.

Domestic companies such as Danor and Shandong Shenyuan are driving the isopropanol industry towards high-end and green development through technological research and development and capacity expansion. In the future, isopropanol will not only continue to play the role of "industrial lifeblood," but will also become an important force driving sustainable development.
