General description
There are odors like a mixture of ethanol and acetone, which have a slightly bitter taste and are flammable. Can be mixed with water, ethanol, diethyl ether and chloroform and is insoluble in saline solutions. Can form azeotropic mixture with water (12.3% aqueous). Easy generation of peroxides. Low toxicity, median lethal dose (rats, by mouth) 2524 mg / kg. High concentration vapors are anaesthetic. Irritant. Solvents for creosote, shellac, resins, gums, nitrocellulose. Esterification analysis solvent determination of vegetable oils barium, calcium, copper, magnesium, nickel, potassium, sodium and strontium. Determination of potassium content of soil and plants by sodium cobalt nitrite isopropanol method, extraction of alkaloids, pesticide analysis, etc. Organic synthesis. Combination of antifreezes. Was used to precipitate DNA
