4-hydroxy-4-methyl-2-pentanone usage and synthesis

chemical properties	colourless liquid
general description	a clear colorless liquid with a pleasant odor. flash point below 141°f. less dense than water. vapors heavier than air.
air & water reactions	highly flammable. soluble in water.
reactivity profile	acetyl bromide reacts violently with alcohols or water, [merck 11th ed., 1989]. mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid, [chem. eng. news 45(43):73(1967); j, org. chem. 28:1893(1963)]. alkyl hypochlorites are violently explosive. they are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. chlorine plus alcohols would similarly yield alkyl hypochlorites. they decompose in the cold and explode on exposure to sunlight or heat. tertiary hypochlorites are less unstable than secondary or primary hypochlorites, [nfpa 491 m, 1991]. base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. such reactions in the absence of solvents often occur with explosive violence, [wischmeyer(1969)].
health hazard	vapor is irritating to the mucous membrane of the eye and respiratory tract. inhalation can cause dizziness, nausea, some anesthesia. very high concentrations have a narcotic effect. the liquid is not highly irritating to the skin but can cause dermatitis.
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.
