This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1860 Excerpt: ...Berthelot. ('1853.) N. Ann. Chim. Phys. 39,16; abstr. Compi. rend 26, 428; Ann. Pharm. 88, 347; J. pr. Chem. 59, 141. Formation. By continued heating of oil of turpentine under pressure. Preparation. English oil of turpentine (from Pintts Auitralis) is heated for three hours to 300 in a sealed tube; the portion which goes over below 230C is redistilled and rectified; and the distillate obtained between 176 and 18 is rectified. Propertiei. Thin, colourless, strongly refracting liquid, of sp. gr. 0-8432 at 22J, boiling between 176 and 178D, and having a lasvo-rotatory power = 10 (varying however with the duration and intensity of the heating, and the nature of the oil of turpentine used in the preparation). It smells like stale lemon-peel. Berthelot. 20 C 120.... 88-23 88-1 16 H. 10.... 11-77 11-7 130.... 100-00 99-8 Tho loevo-rotatory power of isoterebenthene is reduced from 8'8 to 7'0, by heating the liquid to 100' for 30 hours with aqueous oxalic acid.--In 33 days it absorbs 1C-8 p. c. oxygen, and gives off 1 p. c. carbonic acid. Comlinations, With Water.--When a mixture of 4 pts. isoterebenthene, 3 pts. alcohol, and 1 pt. uitrlc acid is left to evaporate in a shallow basin exposed to the air, crystals are formed in the course of a week, resembling turpentine-camphor in all their properties, while the mixture acquires the odour emitted in the formation of turpentinecamphor. With Hydrochloric acid.--Isoterebenthene absorbs 34 p. c. hydrochloric acid gas at 24, and forms a liquid mixture of hydrochlorato of terebene and bi-hydrochlorate of turpentine-oil: 3C-H16 + 4HC1 = 2 (CW.HCl) + O-H,"2HC1. In contact with fuming hydrochloric acid for four weeks, it forms crystals of bi-hydrochlorate of turpentine oil. Isoterebentheno absorbs 14'3 p. c. ff...
