it can be used as the chemical reagents for experimental purpose and chromatography reagents. it can be used as the extraction solvent as well as carrier solvent. gb 2760-1996: temporary food spices allowed for application. it can be applied to the processing of beet sugar, candy, nutritional supplement tablets, hops extract, lemon oil, spice oleoresins, and yeast. as the organic raw material and solvent, it has a wide range of applications and materials. as a chemical raw material, it can be used to produce acetone, hydrogen peroxide, methyl isobutyl ketone, di-isobutyl ketone, isopropylamine, isopropyl ether, isopropyl alcohol ether, isopropyl chloride, isopropyl fatty acids ester and chlorinated isopropyl fatty acid. in the fine chemical industry, it can be used for the production of iso-propyl nitrate, proxam, tri-isopropyl phosphite, tri-isopropyl aluminum and pharmaceuticals and pesticides. as the solvent, it can be used for the production of coatings, inks, extraction solvent, and aerosol. it can also be used as antifreeze, detergents, additive for reconciling gasoline, dispersant of pigment production, the fixer of the industrial printing and dyeing and the antifogging agent of glass and transparent. isopropanol is an important intermediate in the production of pesticides. it can be used to produce fungicides such as isoprothiolane and iprobenfos; insecticide and acaricide such as propetamphos, isocarbophos, isofenphos-methyl, propoxur, and fenvalerate as well as herbicides propisochlor. it can also be used to prepare isopropyl bromide and isopropyl chloride. it is mainly used in pharmaceutical, also used as a solvent, extraction agent, antifreeze agent, etc. purposes: for the pharmaceutical, cosmetics, plastics, fragrances, paint, etc. it can be used as the solvent of creosote, shellac, resins, gums, and nitrocellulose. it can also be used as the solvent for determination of vegetable oil through esterification analysis. it can also used for determination of barium, calcium, copper, magnesium, nickel, potassium, sodium and strontium. it can be used for the extraction of rare earth and metal extraction and separation. it can also be used for the extraction of alkaloids. it can be applied to the pesticide analysis as well as being used for organic synthesis. it is also used as the component of the antifreeze agent. |
production method |
the preparation method is based on using propylene as raw materials and diatomaceous earth phosphate as the catalyst for hydration into isopropanol in a pressurized condition. the process is increasing the pressure of propylene and water separately to 2.03 mpa, and preheated to 200 °c and further mixing them and putting into the reactor for hydration reaction. the reactor contains phosphate diatomaceous earth as the catalyst; the reaction temperature was 95 °c and the pressure is 2.03 mpa; the molar ratio of water to propylene is from 0.7:1; the propylene conversion rate was 5.2% with a selectivity of 99%; the reaction gas was further subject to neutralization and heat exchange and put into the high pressure cooler and high-pressure separator; the gas phase of isopropanol is recycled from the recovery column using saline spray; the unreacted gas was recycled for using via recycle compressor; the liquid phase is low concentration of isopropanol (15% to 17%) which is put into the crude distillation column to generate 85% to 87% isopropyl propanol aqueous solution; this is further subject to the distillation in distillation column to 95%. the purity is further increased to over 99% through benzene extraction. this method is the main method of domestic and foreign production of isopropanol. the method has no sulfuric acid without any corrosion problems. the process is relatively simple. there is also a sulfuric acid hydration method, namely using over 50% propylene as raw materials; the propylene is absorbed with 75% to 85% concentrated sulfuric acid at 50 ℃ and at low pressure in the absorber. dilute the absorption solution to a sulfuric acid content of 35%; use low pressure steam to hydrolyze into isopropanol in the desorption tower. the propylene conversion rate of this method can be over 90% with the crude isopropanol product containing isopropanol of up to 50% to 60%. however, this method uses sulfuric acid with great corrosion on the equipment; in addition, the dilute sulfuric acid needs to be concentrated for recycling usage. ch3ch = ch2 + h2so4 → (ch3) 2choso3h [h2o] → (ch3) 2choh + h2so4 |

general description | volatile, colorless liquid with a sharp musty odor like rubbing alcohol. flash point of 53°f. vapors are heavier than air and mildly irritating to the eyes, nose, and throat. density approximately 6.5 lb / gal. used in making cosmetics, skin and hair preparations, pharmaceuticals, perfumes, lacquer formulations, dye solutions, antifreezes, soaps, window cleaners. sold in 70% aqueous solution as rubbing alcohol. |
air & water reactions | highly flammable. water soluble. |
reactivity profile | isopropanol reacts with air or oxygen to form dangerously unstable peroxides. contact with 2-butanone increases the rate of peroxide formation. an explosive reaction occurs when isopropanol is heated with (aluminum isopropoxide + crotonaldehyde). forms explosive mixtures with trinitromethane and hydrogen peroxide. reacts with barium perchlorate to form a highly explosive compound. ignites on contact with dioxygenyl tetrafluoroborate, chromium trioxide and potassium-tert-butoxide. vigorous reactions occur with (hydrogen + palladium), nitroform, oleum, cocl2, aluminum triisopropoxide and oxidizing agents. reacts explosively with phosgene in the presence of iron salts. incompatible with acids, acid anhydrides, halogens and aluminum . isopropanol can react with pcl3, forming toxic hcl gas.

health hazard | vapors cause mild irritation of eyes and upper respiratory tract; high concentrations may be anesthetic. liquid irritates eyes and may cause injury; harmless to skin; if ingested causes drunkenness and vomiting. |
fire hazard | highly flammable: will be easily ignited by heat, sparks or flames. vapors may form explosive mixtures with air. vapors may travel to source of ignition and flash back. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapor explosion hazard indoors, outdoors or in sewers. runoff to sewer may create fire or explosion hazard. containers may explode when heated. many liquids are lighter than water. |
