The concept and use of isopropyl alcohol
An important chemical product and raw material. Mainly used in pharmaceutical, cosmetic, plastic, fragrance, paint and electronic industries as dehydrating agents and cleaning agents.
Determination of barium, calcium, magnesium, nickel, potassium, sodium and strontium and other reagents. Chromatographic analysis of reference materials. electronics industry. In many industrial and consumer products, Isopropyl Alcohol is used as a low-cost solvent and also as an extractant. According to the European Solvents Industry Group (ESIG), the demand for intermediates in Europe accounted for 32% of isopropanol consumption in 2001, of which 14% was used as an anti-icing agent, 13% was used in paints and resins, and 9% was used in for pharmaceuticals, 4% for food, 3% for inks and adhesives.
Isopropyl alcohol is also used as a solvent for oils and gels and in the manufacture of fishmeal in concentrated feeds. The quality of isopropyl alcohol in automotive fuel is low. Consumption of isopropanol as a raw material for acetone is declining. Several compounds are synthesized from isopropanol, such as methyl isobutyl ketone and many esters. End-use supplies vary according to the quality of isopropyl alcohol. Anhydrous isopropyl alcohol is 99% of the conventional quality, while the content of special grade isopropyl alcohol is more than 99.8% (for flavors and medicines). For the preparation of acetone, diisopropyl ether, isopropyl acetate, thymol, etc. In many cases, alternatives to ethanol are used.
