Terphenyl, hydrogenated

Description

Hydrogenated terphenyls are a complex mix-ture of partially hydrogenated terphenyl isomers. They areclear, oily, pale-yellow liquids with a faint odor. Molecularweight = 241.00; 298.00 (40% hydrogenated); Specificgravity (H2O:1l) = 1.00; Boiling point = 340℃ (40% hydro-genated); FreezingMelting point= 148℃ (40% hydroge-nated); V aporpressure= 13 Paat25℃;Flashpoint= 157℃ (cc); Autoignition temperature = 374℃.Insoluble in water.

General Description

Clear, oily, pale-yellow liquid with a faint odor. A mixture of numerous compounds and isomers depending on the degree and conditions of hydrogenation The 40% hydrogenated mixture has bp: 340°C, density: 1.00 g cm-3, and is insoluble in water. Used as a plasticizer and as a heat-transfer medium. Can be absorbed through the skin and by ingestion.

Reactivity Profile

Terphenyl, hydrogenated are non-flammable (flash-point 157°C for 40% hydrogenated mixture), but combustible. Resist decomposition but break down to produce acrid smoke when heated sufficiently. Incompatible with strong oxidizing agents.

Potential Exposure

These materials are used as; high-tem-perature heat-transfer media and as p lasticizers.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once andirrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek med-ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled,remove from exposure,begin rescue breathing (using universal precautions, includ-ing resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medi-cal attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

storage

Color Code- Green: Generalstorage may beused. Prior to working with this chemical you should betrained on its proper handling and storage. Store in tightlyclosed containers in a cool, well-ventilated area away fromoxidizers. W here possible, automatically pump liquid fromdrums or other storage containers to process containers.

Incompatibilities

Strong oxidizers. W hen heated, iritatingvapors will be released.
