Fig. 12.4. Vapor-to-water transfer data for saturated hydrocarbons as a function of accessible surface area, from [131]. Standard states are 1M ideal gas and solution phases. Linear alkanes (small dots) are labeled by the number of carbons. Cyclic compounds (large dots) are a = cyclooctane, b = cycloheptane, c = cyclopentane, d = cyclohexane, e = methylcyclopentane, f = methylcyclohexane, g = cA-l,2-dimethylcyclohexane. Branched compounds (circles) are h = isobutane, i = neopentane, j = isopentane, k = neohexane, 1 = isohexane, m = 3-methylpentane, n = 2,4-dimethylpentane, o = isooctane, p = 2,2,5-tri-metbylhexane.

Attacks aluminum, copper, lead, tin, zinc, and alloys. Thermal decomposition releases toxic nitrogen oxides. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or COj extinguishers. CYCLOHEPTANE (291-64-5) C,H,4 Highly flammable liquid. Forms explosive mixture with air [explosion limits in air (vol %) 1.1 to 6.7 flash point 43°F/6°C Fire Rating 3]. Violent reaction with strong oxidizers concentrated nitric acid. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, or COj extinguishers. 

SUBCHLORIDE of MERCURY (10112-91-1 7546-30-7) see mercurous chloride. SUBERANE (291-64-5) see cycloheptane. SUCCINIC ACID (110-15-6) C4HSO4 Combustible solid. Dust or powder may form explosive mixture with air. Violent reaction with strong acids, strong oxidizers. Decomposes in elevated temperatures above 455°F/235°C, forming succinic anhydride. Violent reaction with all bases (exothermic reaction) including amines, amides, and inorganic hydroxides strong oxidizers, furfuryl alcohol (explosion), hypochlorites, isocyanides, nitromethane, chromic acid. 

CYCLOHEPTANE (291-64-5) Forms explosive mixture with air (flash point 43°F/6°C). Violent reaction with strong oxidizers. 

Diborane in tetrahydrofuran added with vigorous stirring during 0.5 hr. at 0° under Ng to 1,6-heptadiene in tetrahydrofuran, kept 2 hrs. at 0°, allowed to warm to room temp., methanolic KOH added slowly followed by aq. Ag-nitrate, and stirred 1 hr. at room temp. cycloheptane. Y 67%. F. e. s. R. Murphy and R. H. Prager, Tetrah. Let. 1976, 463. 

Asoln.of cycloheptyl bromide in tetrahydrofuran injected at 25° into a vigorously stirred soln. of lithium hydridotriethylborate in the same solvent, and stirring continued 3 hrs. cycloheptane. Y 99%. - Lithium hydridotriethylborate is a nucleophilic reducing agent far superior to LiAlH4. Compared to LiBH4, its nucleophilicity is enhanced by a factor of 10,000. F. e. s. H. C. Brown and S. Krishnamurthy, Am. Soc. 95, 1669 (1973) replacement with NaAlH iOCH.,-in the presence of palladium chloride complexes cf. I. Simunek and M. Kraus, Coll. 38, 1786 (1973).
