Large tree, 18-30 M. (60-100 degrees) high, .3-.6 M. (1-2 degrees) thick; bark thin, scaled, furrowed; wood hard, resinous; leaves many, crowded at end of branches, in 3's 25-40 Cm. (10-16') long, very narrow, sharp-pointed, triquetrous, in clusters surrounded by a sheath 25 Mm. (1') long; flowers sterile in violet aments, 5 Cm. (2') long' Fruit cone, large, oblong, 15-25 Cm. (6-10') long, scales armed with short spine. Oleoresin -- Terebinthina, Turpentine, N.F. Concrete oleoresin containing not more than 2 p.c. of foreign matter, occurs in yellowish, opaque masses, lighter internally, sticky, more or less glossy, brittle in cold; odor and taste characteristic; freely soluble in alcohol, ether, chloroform, glacial acetic acid; alcoholic solution acid reaction: rarely seen as yellow, opaque, viscid liquid.


(CONCRETE) OLEORESIN: Volatile oil 20-30 p.c., Rosin (resina, resin) 50-60 p.c., bitter principle, formic, succinic, and possibly other resin acids--pinic and sylvic acids.

1. Oleum Terebinthinae. Oil of Turpentine, CH. -- Obtained by distilling with water or steam the (concrete) oleoresin (turpentine); it is a colorless liquid, characteristic odor and taste, both becoming stronger and less pleasant on aging or exposure (owing to formation of ozone, resin, formic and acetic acids), soluble in 5 vols. of alcohol, sp. gr. 0.861, rotation--dextro (variable), with hydrochloric acid forms artificial crystalline camphor, CHHCl; contains chiefly d-pinene (French oil l-pinene), also derivatives of pinene, and often camphene and fenchone.  Tests: 1. Evaporate 5 cc. over boiling water -- residue .1 Gm. (abs. of petroleum, paraffin, rosin oils).  2. Expose to air 3 drops on unsized white paper -- evaporates without leaving permanent stain (abs. of fixed oils).  3. Shake vigorously 5 cc. with equal volume of  hydrochloric acid -- only a light straw-yellow color in either acid or oily layer on standing 5 minutes, no brown or green.  Must be added to fuming acids drop by drop, and should be kept cool, in well-stoppered containers.


Tar oils, kerosene, petroleum benzin, paraffin oils, rosin oil, etc.

2. Resina. Rosin. -- This residue, left after distilling off the volatile oil from the (concrete) oleoresin (turpentine), is usually in sharply angular, translucent, amber-colored fragments, frequently covered with a yellow dust, fracture brittle at ordinary temperatures shiny and shallow-conchoidal; odor and taste slightly terebinthinate; freely soluble in alcohol, ether, benzene, glacial acetic acid, fixed or volatile oils, dilute solutions of the fixed alkali hydroxides; contains anhydride of abietic acid, CHO, 80-90 p.c., pinic and sylvic acids.  Tests: 1. Alcoholic solution--acid; sp. gr. 1.08.  2. Easily fusible and burns with a dense yellowish smoke; ash .05 p.c.  3. Shaken with warm diluted alcohol -- abietic anhydride converted into abietic acid, CHO, crystalline; boiled with alkaline solution -- greasy salts of abietic acid (rosin soap); distil with super-heated steam -- benzene and toluene.  The varieties depend upon color, and this upon degree of heat employed in distillation; the older the trees, the greater the yield of rosin, the smaller the yield of oil.


The P. Palustris (P. Austra'lis -- i.e., southern) grows in dry sandy soil from the sea to 100 miles (160 Km.) inland, the young trees resembling brooms, the older furnishing (Florida, Georgia, N. And S. Carolina) most of the turpentine and rosin of commerce.  The oleoresin secretes in the sapwood, and sparingly exudes spontaneously, so that to obtain it economically on a large scale the trees are cornered and chipped, which consists in removing, according to size of tree, one or two sections of bark -- each one-fourth the entire circumference, and a foot from the ground upward 4-5 feet -- then hacking the exposed wood in shape of the letter L, which may be extended slightly higher every few weeks to increase the flow.  Formerly at the base of each decorticated section the experienced axman cut a triangular-shaped cavity (box -- boxing), 4-8 pints (2-4 L.), capacity, to catch the exudation, which was ladled out with "turpentine dippers" every 2-3 weeks, poured into barrels (250 pounds; 110 Kg.) and subsequently distilled at a nearby station. But these deep-seated wounds were so depleting as to render the trees worthless, save for lumber, in 4-5 years, consequently this method has been replaced by the less destructive "cup and gutter system," which consists in suspending from a zinc nail near the base of scarified section a detachable terra cotta (Herty) or zinc cup, similar in appearance to the quart-flower pot, and above that nailing at incline, on either side of median line, a zinc gutter, 6 x 2', to direct flow into the cup, which, when filled, is easily removed, emptied into barrels and returned.  The first season's yield is about 100 gallons per 100 trees, diminishing thereafter.  The "crude" begins to flow early in March, becomes most rapid July-August when hot and dry, then slackens September-October.  The first year's product is best, virgin dip, yielding 6 ½ gallons (24 L.) of oil per barrel and "window'glass rosin;" succeeding years give yellow dip, yielding 4 gallons (15 L.) of oil per barrel and medium grades of rosin; some hardens on trees, scrapings, scrape, yielding 2 gallons (7.5 L.) of oil per barrel and brownish-black rosin.  In France covered pails or cups with lips, to avoid evaporation, chips, bark, etc., are used, into which the sap flows by a gutter through comparatively small hacked spaces, which, when alternating 5 working with 2 resting seasons, insures a handsome yield for 2 generations.  The comminuted wood has been distilled with water, steam, alkali, etc., but with questionable satisfaction.

In the distillation of concrete oleoresin, when the volatile oil ceases to come over, the resin (rosin) while hot is run off from the bottom of still and strained into barrels, while the condensed distillate (oil), floating above the water, is dipped out and barrelled for market.

Pix Pini, Pine Tar, U.S.P.  (Syn., Pix  Pin., Pix Liquidae, Resina Empyreumatica Liquida; Fr. Goudron vegetal; Ger. Holztheer, Theer.)  A product obtained by the destructive distillation of the wood of Pinus palustris or other species of Pinus (P. Tae'da, P. rig'ida, P. sylves'tris, and Larix sibir'ica.)


Refuse pine wood, cut in billets, is stacked compactly and covered with earth, except an opening at the apex for ignition and the escape of gases; slow combustion without flame is allowed to proceed, while a ditch at the bottom serves to run off the tarry liquid that is ladled into barrels; the wood is converted into charcoal and this becomes a valuable by-product.  In Europe permanent clay furnaces are used over and over.  It is a true, impure turpentine, semi-liquid, viscid, black-brown, non-crystalline, translucent in thin layers, granular and opaque with age; odor empyreumatic, terebinthinate, taste sharp, empyreumatic; miscible with alcohol, ether, chloroform, glacial acetic acid, fixed or volatile oils; heavier than water, slightly soluble in it -- solution pale yellowish-brown, acid reaction; ash .25 p.c.  Test: 1. Shake 1 cc., for 10 minutes, with water 10, add to filtrate a drop of ferric chloride T.S. -- greenish, then brown color.  Dose, gr 5-30 (.3-2 Gm.), in pill.


Acetic acid, small quantities of formic, propionic, capronic acids, acetone, methyl alcohol, mesit, toluol, xylol, cumol, methol (all passing over with the light oil of tar), naphthalene, pyrene, chrysene, paraffin, phenols, creosote (25 p.c.), pyrocatechin, empyreumatic resin.
