General Description
White crystals with a strong phenol odor Slightly soluble to soluble in water, depending on the isomer, and denser than water. Noncombustible. Used as an intermediate in organic synthesis of dyes and drugs.
Reactivity Profile
CHLOROPHENOLS, SOLID are incompatible with acid chlorides, acid anhydrides and oxidizing agents. Also incompatible with iron . Liquefy and darken in color at temperatures above 108°F.
Air & Water Reactions
Slightly soluble to soluble in water.
Hazard
Toxic by skin absorption, inhalation, or
ingestion; strong irritant to tissue.
Health Hazard
Inhalation causes headache, dizziness, weak pulse. Ingestion causes irritation of mouth and stomach; headache, dizziness, weak pulse. Contact with eyes causes severe irritation and burning. Contact with skin causes irritation and burn; if absorbed, causes same symptoms as inhalation.
Potential Exposure
Monochlorophenols are used in the
manufacture of fungicides, slimicides, bactericides, pesticides, herbicides, disinfectants, wood and glue preservatives; in the production of phenolic resins; in the extraction
of certain minerals from coal; as a denaturant for ethanol;
as an antiseptic; as a disinfectant, and others.
Fire Hazard
Special Hazards of Combustion Products: Toxic and irritating hydrogen chloride and chlorine gases may form in fires.
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
UN 2020 (solid); UN2021 (liquid) Chlorophenols, solid and liquid, Hazard Class: 6.1; Labels:
6.1-Poisonous materials.
Incompatibilities
May form explosive mixture with air.
Contact with oxidizing agents can cause fire and explosion
hazard. Heat produces hydrogen chloride and chlorine.
Corrosive to aluminum, copper and other chemically active
metals.
Chemical Properties
All isomers have a characteristic odor.
Chemical Properties
off-white to light tan crystals or powder
Waste Disposal
Incinerate in admixture with
flammable solvent in furnace equipped with afterburner
and scrubber.
Uses
Biocide; disinfectant for home, hospital and farm.
Uses
Intermediates of Liquid Crystals
Definition
ChEBI: A monochlorophenol substituted at the pare position by a chlorine atom.
Flammability and Explosibility
Notclassified
Purification Methods
Distil the phenol, then crystallise it from pet ether (b 40-60o) or hexane, and dry it under vacuum over P2O5 at room temperature. [Bernasconi & Paschalis J Am Chem Soc 108 2969 1986, Beilstein 6 IV 820.]
