Dufour s gland, which is part of the poison-gland complex in ants, often contains complex mixtures of aliphatic hydrocarbons and other fatty-acid-derived compounds. Terpenoids are less common,... 

Carboxylic acids contain the -C(0)0H functional group bound to an aliphatic, olefinic, or aromatic hydrocarbon moiety. This section deals with those carboxylic acids that contain only C, H, and O. Carboxylic acids that contain other elements, such as trichloroacetic acid (a strong acid) or deadly poisonous monofluoroacetic acid, are discussed in later chapters. Some of the more significant carboxylic acids are shown in Figure 14.6. 

Flammable Liquid SAFETY PROFILE Poison by intraperitoneal route. Mildly toxic by inhalation. A local irritant and narcotic in high concentration. Ingestion can cause liver damage. A dangerous fire hazard when exposed to heat or flame. When heated to decomposition it emits toxic fiimes of Br". See also BROMIDES and CHLORINATED HYDROCARBONS, ALIPHATIC. 

OSHA PEL TWA 0.1 ppm STEL 0.3 ppm ACGIH TLV TWA 0.1 ppm STEL 0.3 ppm DOT CLASSIFICATION 6.1 Label KEEP AWAY FROM FOOD SAFETY PROFILE Poison by subcutaneous and intravenous routes. Narcotic in high concentration. Mixmre with Li particles is an impact-sensitive explosive. Explodes on contact with hexacyclohexyldilead. When heated to decomposition it emits toxic fumes of Br . See also CHLORINATED HYDROCARBONS, ALIPHATIC. 

DOT CLASSIFICATION 6.1 Label Poison (UN 1695) DOT Class Forbidden SAFETY PROFILE Poison by inhalation, ingestion, and skin contact. Mutation data reported. A lachrymator poison gas. See also CHLORINATED HYDROCARBONS, ALIPHATIC ACETONE. Flammable when exposed to heat or flame, or oxidizers. 

DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE Poison by inhalation and intravenous routes. Moderately toxic by ingestion and subcutaneous routes. An irritant. Questionable carcinogen with experimental carcinogenic data. Flammable when exposed to heat or flame. Moderately explosive by spontaneous chemical reaction. To fight fire, use water, CO2, dry chemical. Dehalogenation by reaction with alkalies, metals, etc., will produce spontaneously explosive chloroacetylenes. Violent reaction with NaK aUoy + bromoform. Mixtures with potassium are very shock-sensitive explosives. When heated to decomposition it emits highly toxic fumes of Cl". See also CHLORINATED HYDROCARBONS, ALIPHATIC. 

SAFETY PROFILE A poison. The chlorinated naphthalenes have toxic effects on the skin and liver. See also CHLORINATED HYDROCARBONS, ALIPHATIC and POLYCHLORINATED BIPHENYLS. 

DFG MAK Confirmed Animal Carcinogen, Suspected Human Carcinogen SAFETY PROFILE Confirmed carcinogen. Poison by ingestion. Moderately toxic by inhalation and skin contact. Experimental reproductive effects. A skin and severe eye irritant. Mutation data reported. Moderately flammable by heat, flames (sparks), or powerful oxidizers. See also v LLYL COMPOUNDS and CHLORINATED HYDROCARBONS, ALIPHATIC. When heated to decomposition it yields highly toxic Cr. To fight fire, use water (as a blanket), spray, mist, dry chemical. 

The residence times were long (30 minutes) and the catalyst-reagents were consumed and/or poisoned by products. A variety of compositions and conditions were exemplified. By the use of Pt to activate methane, these Exxon workers showed that CH can be converted to a large number of aliphatic and aromatic hydrocarbons, a small fraction of the products being ethylene plus ethane.
