The butylphenols include several isomers. Solid butylphenols (28805-86-9) generally have properties similar to the above:

Butylphenols may be used as intermediates in manufacturing varnish and lacquer resins; as a germicidal agent in detergent disinfectants; as a pour point depressant, in motor-oil additives; de-emulsifier for oil; soap-antioxidant, plasticizer, fumigant, and insecticide

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

UN2430 Alkylphenols, solid, n.o.s. (including C2-C12 homologues), Hazard class: 8; Labels: 8— Corrosive material

Vapors may form explosive mixture with air. These phenol/cresol materials can react with oxidizers; reaction may be violent. Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may cause the gas to ignite and explode. Heat is also generated by the acid-base reaction with bases; such heating may initiate polymerization of the organic compound. React with boranes, alkalies, aliphatic amines, amides, nitric acid, sulfuric acid. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). These reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid and can explode when heated. Many phenols form metal salts that may be detonated by mild shock

The butylphenols include several isomers.The two most highly regulated are o-sec-butylphenol and ptert-butylphenol. Their properties are as follows:o-sec-isomer (89-72-5): Colorless liquid or solid (below16℃). Molecular weight = 150.22; Boiling point =108℃;Flash point = 108℃. Insoluble in water.p-tert-isomer (98-54-4): White crystalline solid. Molecularweight = 150.24; Boiling point = 237℃; Freezing/Melting point = 97℃; Flash point = 115℃ (oc); HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 1, Reactivity 0. Insoluble in water.

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with butyl phenol you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, wellventilated area. Metal containers involving the transfer ofthis chemical should be grounded and bonded. Drums mustbe equipped with self-closing valves, pressure vacuumbungs, and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof this 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.

Inhalation may cause irritation tonose, throat, and lungs. Sensitization may occur. Skin contact studies with animals suggest that severe irritation atconcentrations above 10% may occur. May cause rash, redness, and irritation, especially when skin is wet. Absorptionis significant and contact may lead to allergic reaction. Eyestudies with animals suggest that severe irritation mayoccur. Ingestion studies on animals suggest that 8 oz maybe lethal to a 150-lb person.

May cause skin color changes bycontact or inhalation of levels between 10 and 100 ppm.Allergy may develop after repeated exposure. Liver damagemay also occur. There is limited evidence that butylphenolcauses skin cancer in animals. Repeated or prolonged skincontact can cause skin ulcers and lead to permanent loss ofskin pigment in affected areas.

Wear protective gloves andclothing to prevent any reasonable probability of skincontact. Safety equipment suppliers/manufacturers canprovide recommendations on the most protective glove/clothing material for your operation. All protective clothing (suits, gloves, footwear, headgear) should be clean,available each day, and put on before work. Contactlenses should not be worn when working with this chemical. Wear splash- or dust-proof chemical goggles and faceshield unless full face-piece respiratory protection isworn. Employees should wash immediately with soapwhen skin is wet or contaminated. Provide emergencyshowers and eyewash.

Butylphenol is combustible. Use drychemical, carbon dioxide, or foam extinguishers. Poisonousgases are produced in fire. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fireofficials and pollution control agencies. From a secure,explosion-proof location, use water spray to cool exposedcontainers. If cooling streams are ineffective (venting soundincreases in volume and pitch, tank discolors, or shows anysigns of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must betrained and equipped in OSHA 1910.156. The only respirators recommended for firefighting are self-contained breathing apparatuses that have full face-pieces and are operatedin a pressure-demand or other positive-pressure mode.
