Ethane Standards and Recommendations
DOT Classification: 2.1; Label: Flammable Gas
Ethane Specification
This chemical is called Ethane, and its CAS registry number is 74-84-0. With the classification code Simple asphyxiant, its product categories are Refrigerants; Organics; Chemical Synthesis; Compressed and Liquefied Gases; Synthetic Reagents. Additionally, it's colorless gas which is incompatible with strong oxidizing agents. It could be produced by the method of cracked gas and cryogenic. However, this chemical is highly flammable and it will readily form explosive mixtures with air.
Other characteristics of the Ethane can be summarised as followings: (1)ACD/LogP: 1.73; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.726; (4)ACD/LogD (pH 7.4): 1.726; (5)ACD/BCF (pH 5.5): 12.075; (6)ACD/BCF (pH 7.4): 12.075; (7)ACD/KOC (pH 5.5): 207.034; (8)ACD/KOC (pH 7.4): 207.034; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0 ; (12)Index of Refraction: 1.294; (13)Molar Refractivity: 11.315 cm3; (14)Molar Volume: 61.549 cm3; (15)Polarizability: 4.485×10-24cm3; (16)Surface Tension: 10.857 dyne/cm; (17)Density: 0.489 g/cm3; (18)Flash Point: °C; (19)Enthalpy of Vaporization: 16.84 kJ/mol; (20)Boiling Point: °C at 760 mmHg; (21)Vapour Pressure: 28534.01 mmHg at 25°C.
Production method of this chemical: The Ethane could be obtained by the reactant of ethene. This reaction needs the reagents of Pd and hydrogen.
Uses of this chemical: The ethane is widely used as a standard gas, etching gas, standard gas-line instrumentation, the evaluation of the catalyst gas in the chemical industry, metallurgy, electronics, oil and other industrial sectors and scientific research, aviation, atomic energy and other fields. It's also mainly used as raw material for the production of ethylene and for the manufacture of oxide and ethyl bromide and so on in petrochemical industry. In addition, it could be used for making bromoethane. This reaction needs the reagent of CBr4*2AlBr3 and the temperature of 55-60 °C. The yield is 60 %.
When you are using this chemical, please be cautious about it as the following: This chemical is extremely flammable. Keep it away from sources of ignition. Please take precautionary measures against static discharges and keep the container in a well-ventilated place.
You can still convert the following datas into molecular structure:
1.SMILES: CC
2.InChI: InChI=1/C2H6/c1-2/h1-2H3
