IPA Isopropyl alcohol
Description:
Isopropyl alcohol (IUPAC name propan-2-ol; commonly called isopropanol or 2-propanol) is a colorless, flammablechemical compound (chemical formula CH3CHOHCH3) with a strong odor. As an isopropyl group linked to a hydroxylgroup, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether.

Usage:
Isopropanol is an important chemical product and raw material. Mainly used in pharmaceutical, cosmetic, plastic, perfume, coating and electronic industry as dehydrating agent and cleaning agent. A reagent for the determination of barium, calcium, magnesium, nickel, potassium, sodium, strontium, etc. Chromatographic analysis of reference substances.
In PCB manufacturing, it is used as a cleaning agent as well as making PCB holes conductive. Many people find it not only can be a good cleaning motherboard, and often can get the best results. In addition, it is also used for other electronic devices, including clean CD cartridges, floppy disk drives, magnetic tape, and CD or DVD players, and laser head drives.
Isopropanol can also be used as a solvent for flexography, lithography, intaglio printing, and as a cleaning agent for equipment. In the ink also often contains this component. It is also an important solvent for laboratory dilution and extraction. Isopropanol is also used as a gasoline additive and as a deicing agent for fuel pipelines.
In the pharmaceutical and cosmetics industry, isopropanol is used in the manufacture of lotion, hand and body lotions, preservatives, and pharmaceutical reddening agents. It is also used in paints, thinners, paints, detergents and polishes, as well as for surface sterilization, hospital disinfection, food processing and so on.
Isopropanol is used as a low-cost solvent and as an extractant in many industrial and consumer products and in many cases as an alternative to ethanol.
Isopropanol is also used as a solvent for oils and colloids and in the manufacture of fish meal feed concentrates. Low quality isopropanol is used in automobile fuels. The use of isopropanol as raw material for acetone production is decreasing. Several compounds are synthesized from isopropanol, such as isopropyl ester, methyl isobutyl ketone, isopropylamine, diisopropyl ether, isopropyl acetate, thymol, and many esters. Different quality isopropanol can be supplied according to the end use. The conventional quality of anhydrous isopropanol is more than 99%, while the content of special-grade isopropanol is more than 99.8% (used in essence and medicine).
