Definition
ChEBI: 1,3-dichloropropan-2-ol is a secondary alcohol that is isopropanol in which one hydrogen of each methyl group is substituted by a chlorine. A liquid at room temperature (melting point -4℃, boiling point 174℃ at 760 mm Hg), it is used as a solvent for hard resins and nitrocellulose. It has a role as a protic solvent and a cross-linking reagent. It is a secondary alcohol and an organochlorine compound.
General Description
A colorless liquid with an ether-like odor. Denser than water and slightly soluble in water. Toxic by ingestion, inhalation or skin absorption and may irritate skin and eyes.
Air & Water Reactions
Denser than water and slightly soluble in water.
Reactivity Profile
A halogenated alcohol. 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
It is used as a solvent for hard resins
and nitrocellulose; in the manufacture of photographic
chemicals and lacquer; as a cement for celluloid; and as a
binder of water colors. It occurs in effluents from glycerol
and halohydrin production plants.
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Medical observation is recommended for 24-48 h afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray.
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with 1,3-dichloro-2-propanol you should be trained on its properhandling and storage. Before entering confined space wherethis chemical may be present, check to make sure that anexplosive concentration does not exist. Store in tightlyclosed containers in a refrigerator under inert atmosphereaway from oxidizers. Metal containers involving the transfer of this chemical should be grounded and bonded. Wherepossible, automatically pump liquid from drums or otherstorage containers to process containers. Drums must beequipped with self-closing valves, pressure vacuum bungs,and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers ofthis chemical. Sources of ignition, such as smoking andopen flames, are prohibited where this chemical is used,handled, or stored in a manner that could create a potentialfire or explosion hazard. Wherever this chemical is used,handled, manufactured, or stored, use explosion-proof electrical equipment and fittings. A regulated, marked areashould be established where this chemical is handled, used,or stored in compliance with OSHA Standard 1910.1045.
