Isopropyl alcohol is an important chemical product and raw material. It is mainly used as dehydrating agent and cleaning agent in pharmaceutical, cosmetics, plastics, perfumes, coatings and electronic industries. Determination of reagents such as barium, calcium, magnesium, nickel, potassium, sodium, and cesium. Chromatographic reference material.
In the circuit board manufacturing industry, it is used as a cleaning agent and PCB hole conduction. Many people find that it can not only clean the motherboard very well, but also often achieve the best results. In addition, it is also used in other electronic devices, including cleaning cartridges, floppy disk drives, magnetic tapes, and laser heads for CD or DVD player optical drives.
Isopropanol can also be used as a solvent for flexo, lithography, gravure printing, and as a device cleaner. It is also often included in inks. It is also an important solvent for dilution and extraction in the laboratory. In addition, isopropyl alcohol is also used as a de-icing agent for gasoline additives and fuel pipelines.
In the pharmaceutical and cosmetic industries, isopropyl alcohol is used in the manufacture of wipes, hand and body lotions, preservatives, and pharmaceutical redners. It is also used in paints, thinners, paints, cleaners and polishes, as well as surface sterilization, hospital disinfection, food processing plants, etc.
In many industrial and consumer products, isopropyl alcohol is used as a low-cost solvent, also as an extractant, and can be used in place of ethanol in many cases.
Isopropanol is also used as a solvent for oils and colloids, as well as in the manufacture of fishmeal feed concentrates. Low-quality isopropyl alcohol is used in automotive fuels. The amount of isopropyl alcohol used as a raw material for acetone production is decreasing. Several compounds are synthesized using isopropanol, such as isopropyl, methyl isobutyl ketone, isopropylamine, diisopropyl ether, isopropyl acetate, thymol, and many esters. Different qualities of isopropanol can be supplied depending on the end use. The normal mass of anhydrous isopropyl alcohol is more than 99%, while the content of isopropyl alcohol of special grade is more than 99.8% (for perfumes and medicines).
Market demand analysis for different purposes
The European Solvent Industry Group (ESIG) stated that in 2001, the demand for European intermediates accounted for 32% of the isopropyl alcohol consumption, 14% of isopropanol was used as anti-icing agent, 13% was used for paint and resin, and 9% was used For drugs, 4% for food and 3% for inks and adhesives.
At present, China's isopropyl alcohol is mainly used as a solvent in the ink and pharmaceutical industries, and its demand accounts for about 50% of the total demand. However, due to the competition of ethanol, the growth trend in this area is predicted to slow down in the future; the demand for organic intermediates is different. Propanol accounts for about 25% of the total demand; other various additives and isopropanol esters account for about 25% of demand. The application of isopropyl alcohol in electronic industrial cleaning agents has become one of the fastest growing areas in the world for isopropyl alcohol demand. China has now become the world's major production base of electronic appliances. China's application in this field has just started and its development potential Huge market prospects.
