| Hazard Information | Back Directory | [Uses]
manufacture of rubber vulcanizers, accelerators and age resisters; in perfumes; ore flotation. | [General Description]
A clear white to yellow syrupy liquid. Denser than water. Flash point 150°F. Contact may irritate skin and eyes. Moderately toxic by ingestion, inhalation and skin absorption. | [Air & Water Reactions]
Soluble in water. | [Reactivity Profile]
An aldehyde and alcohol. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. | [Health Hazard]
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Fire Hazard]
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. | [Potential Exposure]
Aldol is used as a solvent and to manufacture rubber accelerators, perfumes; in fungicides; and in engraving, cadmium plating | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. | [Shipping]
UN2839 Aldol, Hazard Class: 6.1; Labels: 6.1Poison Inhalation Hazard | [Incompatibilities]
Danger! May be subject to spontaneous polymerization. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires orexplosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact with metals may evolve flammable hydrogen gas. Heat above 83 C causes the formation of crotonaldehyde vapor (which may cause explosion) and water.
| [Chemical Properties]
Aldol is a flammable, colorless to pale yellow, syrupy liquid. Pungent odor | [Waste Disposal]
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. | [Purification Methods]
An ethereal solution of aldol is washed with a saturated aqueous solution of NaHCO3, then with water. The non-aqueous layer is dried with anhydrous CaCl2 and distilled immediately before use. The fraction, b 80-81o/20mm, is collected as a thick liquid which decomposes at 85o/atm. It is a sedative and a hypnotic but is used in perfumery. [Mason et al. J Am Chem Soc 76 2255 1954].
