99 Isopropyl Alcohol (abbreviation: IPA) 99% is a clear, colorless, flammable liquid with a distinct odor. It has long been recognized as the universal solvent because it is cost-effective, HAP-free, and less toxic than methanol. Modern manufacturing systems can now produce premium Isopropyl Alcohol in high volumes.
Most IPA (isopropyl alcohol cas67-63-0) is made by hydrating propylene, sometimes also catalytically from acetone. Conversely, Isopropyl Alcohol can also be a precursor of acetone. Isopropanol is the simplest secondary alcohol. Among the three carbon atoms of the molecule is its lone hydroxyl group. Its oxygen is partially negatively charged, while the portion connecting the hydrogen and carbon atoms is positively charged, making IPA a polar molecule. IPA is soluble in water and also dissolves various non-polar compounds such as oils and resins.
Although 99% of IPA is consumed by the electronics and medical device industries, it is also an essential processing agent in alternative fields. We’ll look at some of the main industrial uses of IPA 99% and which grades each might be suitable for.
Since IPA is flammable and an irritant in both liquid and vapor forms, proper precautions should always be taken in storage and handling. These chemicals are intended for use in research, industrial work, cleaning or disinfection and should therefore be stored properly and kept away from young children.
99 Isopropyl Alcohol(cas67-63-0) is a common cleaner and degreaser for cables, connectors, electrical contacts, LCDs, keyboards, glass, fiber optics, cables, keyboards, and tape heads. Since water presents a shock hazard when handling electronic components, anhydrous IPA must be used to clean electronics to be on the safe side. Designed specifically for the manufacture of semiconductors,
Clean room grade 99 Isopropyl Alcohol(cas67-63-0). Additional production steps are required, such as sub-micron filtration, to remove nanoscale contaminants that can damage electronic connections; thus the higher cost of this premium product. Contains only ppm level impurities and each batch is tested for 40 trace metals. As the concentration increases, IPA’s flash point decreases while evaporation accelerates, providing the potential for 99% purity for front-end cleaning of semiconductor wafers, printed circuit boards, and integrated circuits. High purity and non-polar, may be suitable for flushing away etchant salts, metal residues, thermal greases and rosin fluxes. Extremely pure 99% anhydrous IPA is essential for dehydration and final cleaning of wafers, silicon, solar cells and fuel cells.
Application of 99 Isopropyl Alcohol in different industries
Extract
Due to its ability to dissolve non-polar compounds, IPA 99% is often used in the processing of essential oils, fats, fragrances, waxes and nutraceuticals. It has been used to extract phospholipids and Omega-3 fatty acids from fish to make high-quality triglyceride oil. For making resins from botanicals, it can be used as a co-solvent with ethanol, simplifying the process by combining extraction and winterization in one step. When a wax concentrate is preferred, a quick wash extract using 99% IPA may be most effective.
99% of Isopropyl Alcohol is widely used in coating industry
As a reagent for the production of polymers and as a downstream dispersant. Intermediates that can be made from it include acetone, glycerin, methyl isobutyl ketone and bisphenol A, which are common precursors to resins and paints. Methyl methacrylate can be produced by condensation of acetone and hydrogen cyanide, and then copolymerized in IPA solution to produce acrylic acid.
IPA 99% is a common thinner for resins and paints. To impregnate cellulosic or fiberglass substrates with resins, IPA 99% can be used to dilute saturated mixtures to accelerate polymer penetration into the media, which can then be flashed or air dried in an oven. Because it dissolves uncured polymer, workers can also use it to clean tools, equipment or spills.
pharmaceutical
For manufacturing pharmaceuticals, 99% of IPA is used to create, purify and analyze compounds, and to decontaminate reactors. Whether synthesizing amino acids or peptides, it is a protic solvent suitable for many multi-step organic reactions.
IPA 99% is also suitable for running laboratory analyzes such as HPLC, GC, fluorescence or TLC to characterize and quantify chemicals. There is a worldwide shortage of acetonitrile, a common solvent used in reversed-phase HPLC and UPLC, so scientists have developed more eluent systems containing IPA. Since this grade is micron filtered and low in volatiles, no further filtration is required. Since it is controlled by UV absorbance, it is suitable for critical analysis.
molecular biology
Histological grade 99% IPA free of DNases, RNases and nucleic acids, used to prepare samples for downstream molecular reactions, such as spectrophotometric analysis, gel electrophoresis, restriction enzyme analysis, nucleotide sequencing or polymerase chain for nucleic acid detection reaction. When a large number of samples are available, IPA 99% is recommended to concentrate and purify DNA because it is efficient and fast. Keeping conditions at room temperature and minimizing incubation time should help prevent salt precipitation.
car
The automotive industry uses 99% IPA for car care. Auto detailers typically use IPA to remove wax from cars and thin the paint before painting or polishing. Since it’s a defrosting agent, it’s often added to windshield washer fluid or fuel tanks to dissolve water so it doesn’t separate from the gas and freeze in the lines.
personal care products
IPA 99% is often formulated into aftershaves, bath products, cosmetics, hand sanitizers, lotions and perfumes, as an extractant, diluent, defoamer or surfactant. It is widely used in the nail care industry for making polishes and cleaning nails. The 99 Isopropyl Alcohol(cas67-63-0) in the polish helps to apply smoothly and evaporates quickly. Salon staff then cleanse with 99% IPA, leaving the nail surface with a high-shine finish. Personal care products processed with IPA require ACS/USP/NF ratings.
the medical
99% of IPA is used for general disinfection in medical institutions. Hospitals and clinics use IPA to disinfect medical equipment, clean surfaces, and apply skin care and dressings. Due to its low flash point, it should be stored away from sources of ignition.
food industry
The food industry uses 99 Isopropyl Alcohol(cas67-63-0) to treat dyes, glazes, extenders, vinegars, and to sanitize surfaces, reactors, tools, and vats. Since standing water can harbor bacteria, the hydrophilic IPA washes it away, sanitizing the device during the evaporation process. USP Grade IPA is free of toxic contaminants and is suitable for cleaning surfaces used in the manufacture of food or beverages.
in conclusion
The industrial market now has access to 99% ultra-high-purity IPA for the efficient manufacture of small electronic components such as printed circuit boards. Purity depends on the quality and cost of your industrial application. Tianjin Yongda Chemical Reagent Co., Ltd. can provide you with this kind of pure isopropanol, and will provide you with the grade suitable for your use according to your needs, so that you can use it more conveniently, with less walking and more Detours, but also save more costs for you, to achieve the goal of win-win cooperation.
