Products Description of Isopropyl alcohol CAS#67-63-0
Isopropyl alcohol, also known as fire wine, is the simplest secondary alcohol and one of the isomers of n-propyl alcohol. It is a colorless, flammable liquid with a strong odor, similar to the mixture of ethanol and acetone, but not very odorous. It is soluble in most organic solvents such as water, alcohol, ether, benzene, chloroform, etc. It is miscible with water, alcohol, ether, and can form an azeotrope with water. Its vapor can cause slight irritation to the eyes, nose and throat; it can be absorbed by the human body through the skin. Its vapor can form an explosive mixture with air. The explosion limit is 2.0%~12% (volume). It is a medium explosive hazardous item. It is a flammable and low-toxic substance. The toxicity of its vapor is twice that of ethanol, and the toxicity is the opposite when taken orally.

Product Application of Isopropyl alcohol CAS#67-63-0
Isopropyl alcohol is an important chemical product and raw material, mainly used as a dehydrating agent and cleaning agent in the pharmaceutical, cosmetic, plastic, fragrance, coating and electronic industries. Reagents for the determination of barium, calcium, magnesium, nickel, potassium, sodium and strontium. Chromatographic analysis reference material. In the circuit board manufacturing industry, it is used as a cleaning agent and to make PCB holes conductive. In addition, it is also used in other electronic devices, including cleaning CD boxes, floppy disk drives, tapes, and the laser heads of CD or DVD player CD drives. Isopropyl alcohol can also be used as a solvent for flexographic printing, lithography, gravure printing, and as an equipment cleaner. This ingredient is also often included in inks. It is also an important solvent for laboratory dilution and extraction. In addition, isopropyl alcohol is used as a gasoline additive and a deicing agent for fuel pipelines. In the pharmaceutical and cosmetic industries, isopropyl alcohol is used to manufacture scrubbing liquids, hand and body lotions, preservatives, and pharmaceutical rubefacients. It is also used in paints, thinners, coatings, cleaners and polishes, as well as surface sterilization, hospital disinfection, food processing plants, etc.
