| Hazard Information | Back Directory | [General Description]
A colorless oily liquid with a faint aromatic odor. Insoluble in water and denser than water. Strongly irritates skin and eyes. Used to manufacture dyes. | [Reactivity Profile]
BENZYLIDENE CHLORIDE(98-87-3) is incompatible with strong oxidizers and strong bases. BENZYLIDENE CHLORIDE(98-87-3) readily hydrolyzes under acid or alkaline conditions. BENZYLIDENE CHLORIDE(98-87-3) reacts with metals (except nickel and lead). . | [Air & Water Reactions]
Insoluble in water. | [Hazard]
Strong irritant and lachrymator. Probable
carcinogen.
| [Health Hazard]
Acute: vapors are highly irritating to eyes. May be fatal if inhaled, swallowed, or absorbed through skin. | [Potential Exposure]
Benzal chloride is used almost exclusively
for the manufacture of benzaldehyde. It can also be
used to prepare cinnamic acid and benzoyl chloride. | [Fire Hazard]
Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases and may cause pollution. Cylinder may explode in the heat of fire. Reacts with water to release hydrochloric acid. | [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.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy. | [Shipping]
UN1886 Benzylidene chloride, Hazard class 6.1;
Label 6.1—Poisonous materials. | [Incompatibilities]
May form explosive mixture with air.
Reacts with water, air, or heat, forming fumes of hydrochloric
acid. Reacts (possibly violently) with acids, bases,
strong oxidizers; many metals; potassium, sodium, aluminum.
Attacks plastics and coatings. | [Description]
Benzal chloride (dichloromethylbenzene, a,adichlorotoluene, benzylidene chloride) is produced exclusively by the side-chain chlorination of toluene. It was first synthesized in 1848 by A. CAHOURS, by using the reaction of PCl5 with benzaldehyde. Almost the sole application of benzal chloride is in the production of benzaldehyde. | [Chemical Properties]
Benzal chloride is a combustible, fuming,
colorless, oily liquid; fumes on exposure to air. Faint, pungent
odor. | [Chemical Properties]
colourless oily liquid | [Waste Disposal]
Incineration @ 816 C,
0.5 second minimum for primary combustion; 1204 C,
1.0 second for secondary combustion; elemental chlorine
formation may be alleviated through injection of steam or
methane into the combustion process. | [Physical properties]
Benzal chloride is a liquid which fumes in moist
air and which has a pungent odor and a strong
irritant effect on the mucous membranes and eyes.Benzal chloride is freely soluble in alcohol,
ether, chloroform, and carbon tetrachloride, but
only slightly soluble in water (0.05 g/L at 5 ℃;
0.25 g/L at 39 ℃). The solubility of chlorine in
100 g of benzal chloride is
6.2 g at 30 ℃,
4.3 g at 50 ℃,
1.5 g at 100 ℃. | [Uses]
manufacture of benzaldehyde, cinnamic acid. | [Uses]
α,α-Dichlorotoluene has been useds as initiator during the atom transfer radical polymerization (ATRP) of styrene and methyl methacrylate. | [Definition]
ChEBI:Benzal chloride is a member of benzenes. | [Synthesis Reference(s)]
