Reactivity Profile
SALICYLALDEHYDE is an aldehyde. 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.

firefighting, non-fire response, protective clothing, and first aid. The
information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
No information available.
Firefighting
Extinguish with water fog, alcohol foam, CO2 or dry chemical. (USCG, 1999)
Non-Fire Response
Avoid contact with liquid or vapor. Keep people away. Wear goggles and self-contained breathing apparatus. Stop discharge if possible. Isolate and remove discharged material. Notify local health and pollution control agencies. (USCG, 1999)
Protective Clothing
Wear goggles and self-contained breathing apparatus. (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
Call a doctor.
INHALATION: Remove from exposure. Treat respiratory depression with artificial respiration and oxygen.
EYES: Irrigate with water for at least 15 minutes.
SKIN: Wash with soap and water. Remove contaminated clothing.
INGESTION: Induce vomiting with ipecac. Delay absorption by giving activated charcoal. Use saline cathartic. in mild poisoning with adequate urine output and no vomiting, give milk and fruit juice every hour. Treat acidosis with sodium bicarbonate (7.5% solution). (USCG, 1999)

Physical Properties
The
Physical Property fields
include properties such as vapor pressure and
boiling point, as well as explosive limits and
toxic exposure thresholds
The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
