DOT Classification: 3; Label: Flammable Liquid

Specification

The Decahydronaphthalene,with the CAS registry number 91-17-8, is also known as Perhydronaphthalene. Its EINECS number is 202-046-9. This chemical's molecular formula is C₁₀H₁₈ and molecular weight is 138.25. What's more, its systematic name is decahydronaphthalene. Its classification codes are: (1)Human Data; (2)Tumor data. It is flammable liquid with a high flash point. It can be used as a solvent and lubricant for naphthalene, fats, resins, oils, waxes, and it can be used as a substitution of turpentine in lacquers, shoe polishes, floor waxes, in motor fuel & lubricants, patent fuel in stoves. It should be sealed and stored in a cool place with iron, mild steel, copper or aluminum-made containers. It easily forms explosive organic peroxides upon storage in the presence of air.The Decahydronaphthalene can be prepared by naphthalene through catalytic hydrogenation in industry.

Physical properties of Decahydronaphthalene are:
(1)ACD/LogP: 4.93; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 4.93; (4)ACD/LogD (pH 7.4): 4.93; (5)ACD/BCF (pH 5.5): 3300.84; (6)ACD/BCF (pH 7.4): 3300.84; (7)ACD/KOC (pH 5.5): 11487.5; (8)ACD/KOC (pH 7.4): 11487.5; (9)Index of Refraction: 1.469; (10)Molar Refractivity: 44.16 cm³; (11)Molar Volume: 158.4 cm³; (12)Polarizability: 17.51×10^-24cm³; (13)Surface Tension: 29.4 dyne/cm; (14)Density: 0.872 g/cm³; (15)Flash Point: 57.2 °C; (16)Enthalpy of Vaporization: 40.96 kJ/mol; (17)Boiling Point: 190.9 °C at 760 mmHg; (18)Vapour Pressure: 0.735 mmHg at 25°C.

Uses of Decahydronaphthalene:
