Isonitriles are presumed to be toxic, and it is recommended that the workup procedure be performed in a hood. Unlike most isonitriles, however, 1,1,3,3-tetramethylbutyl isonitrile is not malodorous. It has a sweetish pine odor, which becomes unpleasant only after continued inhalation.

Turpentine Oil. The world s largest-volume essential oil, turpentine [8006-64-2] is produced ia many parts of the world. Various species of piaes and balsamiferous woods are used, and several different methods are appHed to obtain the oils. Types of turpentines include dry-distiUed wood turpentine from dry distillation of the chopped woods and roots of pines steam-distilled wood turpentine which is steam-distilled from pine wood or from solvent extracts of the wood and sulfate turpentine, which is a by-product of the production of sulfate ceUulose. From a perfumery standpoint, steam-distilled wood turpentine is the only important turpentine oil. It is rectified to yield pine oil, yellow or white as well as wood spirits of turpentine. Steam-distilled turpentine oil is a water-white mobile Hquid with a refreshing warm-balsamic odor. American turpentine oil contains 25—35% P-pinene (22) and about 50% a-pinene (44). European and East Indian turpentines are rich in a-pinene (44) withHtfle P-pinene (22), and thus are exceUent raw materials... 

Many commercial grades of pine oil are available and are specified by physical properties and total alcohol content. Some commercial pine oils and the typical physical properties are Hsted in Table 4. Other grades of pine oil may constitute a blend of synthetic and natural pine oil and give the product a different odor characteristic. The odor difference is caused by the presence of phenoHc ethers anethole and methyl chavicol. 

Although the different enantiomers of a chiral molecule have the same physical properties, they usually have different biological properties. For example, the (+) enantiomer of limonene has the odor of oranges, but the (-) enantiomer has the odor of pine trees. 

Plants produce a vast array of terpenes, alkenes built in multiples of five carbon atoms. Many terpenes have characteristic fragrances. For example, the fresh odor of a pine forest is due to pinene, a ten-carbon molecule with a ring structure and one double bond. The fragrances of terpenes make them important in the flavor and fragrance industry. Limonene, another ten-carbon molecule with a ring and two double bonds, is the principal component of lemon oil. Geraniol, a chainlike molecule with two double bonds, is one of the molecules that is responsible for the fragrance of roses and is used in many perfumes. Many other terpenes have important medicinal properties. 

Using the CRC Handbook or another table of densities, find the densities for each of the four woods oak, white pine, balsa, and cedar. Record these ranges. Decide which of the woods your sample might represent. Your answer should be based on both your calculated averaged density and your qualitative observations about the sample. For example, find out if any of the wood types emit a distinct odor or are known as a light-colored or dark-colored wood.

Strange as it sounds, the absence of odor often serves as a powerful stimulis unfamiliar and still unmarked objects or areas prompt vigorous scent marking. This applies to many mammals, including ungulates, such as pronghorn, Antilocapra americana (Muller-Schwarze et al, 1972) rodents, such as house mice, Mus musculus (Hurst, 1987), and carnivores (Kleiman, 1966). For example, pine martens, Maries martes, mark most consistently unmarked objects and do not mark objects that already carry their own odor. It is concluded that marking primarily serves familiarization. 

Androgenic compounds occur in various plants. Celery stalks and parsnip roots contain trace amounts of androstenedione (Fig. 11.12), the same compound found in boar odor (Claus and Hoppen, 1979). Testosterone is also found in pollen of Scots pine Pinus sylvestris). 

Hatchling pine snzkes,Pituophismdanoleucus, ofthe Pine Barrens in New Jersey prefer mouse odor in a Y-maze more if they have been incubated at a higher temperature (33 °C versus 28 °C). Furthermore, experience plays a role in this species, too. Snakes that had eaten a mouse detect and follow a mouse odor trail, while naive snakes show no such response (Burger, 1991).
