Acids, Carboxylic

NEODECANOIC ACID is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions.

Each notification may be associated with multiple companies.|Warning|H315 (100%): Causes skin irritation [Warning Skin corrosion/irritation]|P264, P280, P302+P352, P321, P332+P313, and P362|Aggregated GHS information provided by 37 companies from 2 notifications to the ECHA C&L Inventory.

Fire Extinguishing Agents: Water spray, alcohol foam or dry chemical. (USCG, 1999)|Use water spray, foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Neutralizing Agents for Acids and Caustics: Sodium bicarbonate or lime. (USCG, 1999)

When contact is likely wear long sleeves, chemical resistant gloves, and chemical goggles. Where contact may occur wear safety glasses with side shields. Where overexposure by inhalation may occur, wear approved respirator. (USCG, 1999)

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable plastic containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Separated from strong oxidants. Ventilation along the floor. Store in an area without drain or sewer access.

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached.

The substance is irritating to the eyes. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis.

Repeated or prolonged contact with skin may cause dermatitis.

NO open flames. Above 94 °C use a closed system and ventilation.

PREVENT GENERATION OF MISTS!

Use ventilation.

Protective gloves.

Wear safety spectacles.

Irritating to eyes and respiratory tract in high concentrations. May cause hair disorder or damage. (USCG, 1999)

INHALATION: Use proper respiratory protection. Remove the victim from the exposure. Administer artificial respiration if breathing stops. Keep at rest. Call for prompt medical attention. INGESTION: If conscious, INDUCE VOMITING, get prompt medical attention. If unconscious, do not give anything by mouth. SKIN: Flush with large amount of water. Use soap if available. EYES: Immediately flush with large amounts of water. Get prompt medical attention. (USCG, 1999)

Fresh air, rest.

Rinse and then wash skin with water and soap.

Rinse with plenty of water (remove contact lenses if easily possible).
