Isobutane Specification

The Isobutane , with the register number75-28-5, has other names as 1,1-Dimethylethane;2-Methylpropan ; 2-methyl-propan ; a31(hydrocarbon) ; i-Butane ; Isobutan ; Isobutane mixtures ; isobutane(dot) .

The physical properties of this chemcial are as followings: (1)ACD/LogP: 2.70 ; (2)ACD/LogD (pH 5.5): 2.7 ; (3)ACD/LogD (pH 7.4): 2.7 ; (4)ACD/BCF (pH 5.5): 66.02 ; (5)ACD/BCF (pH 7.4): 66.02 ; (6)ACD/KOC (pH 5.5): 698.43 ; (7)ACD/KOC (pH 7.4): 698.43 ; (8)Index of Refraction: 1.352 ; (9)Molar Refractivity: 20.53 cm³ ; (10)Molar Volume: 94.9 cm³ ; (11)Polarizability: 8.14 ×10^-24cm³ ; (12)Surface Tension: 15.5 dyne/cm ; (13)Density: 0.612 g/cm³ ; (14)Enthalpy of Vaporization: 21.3 kJ/mol ; (15)Vapour Pressure: 2580 mmHg at 25°C.

This is a kind of air with no odour and no color but is flammable and combustible. This is stable. And this is widely used in many ways. It could be used as the aerosol and the aerating agent. Besides, it could also be applied in Standard gas for the Petrochemical Corporation analysis and detecting instrument. What's more, it can be used in making the isooctane, and being the improver & refrigerant for the gasoline octane number.

Its product categories are including refrigerants;Organics;Refrigerant;Gas Cylinders;Hydrocarbons (Low Boiling point);Synthetic Organic Chemistry. Besides, its raw materials are in the following: Liquefied petroleum ges, C4 Fraction while its preparation products are the below: Propylene oxide, ISOBUTYLENE, Methacrylic acid, (1R-cis)-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropane carboxylic acid, N-BUTANE, 1-BUTENE, 1R-cis crysanthemic acid, ETHOPERMETHRIN，95%, 2,2,4-Trimethylpentane, etc.

Being a kind of extremely flammable chemical, it has an extremely low flash point and boiling point, and gases that catch fire in contact with air. So while dealing with it, you should be very cautious.
Keep container in a well-ventilated place and keep away from sources of ignition - No smoking

Additionally, you could convert the following data information into the molecular structure:
SMILES:CC(C)C
