Specification
The α-Butene with CAS registry number of 106-98-9 is also known as 1-Butene. The IUPAC name is But-1-ene. It belongs to product categories of Gas Cylinders; Hydrocarbons (Low Boiling point); Synthetic Organic Chemistry; Chemical Synthesis; Compressed and Liquefied Gases; Synthetic Reagents. Its EINECS registry number is 203-449-2. In addition, the formula is C4H8 and the molecular weight is 56.11. This chemical is a colorless gas that insoluble in water and has an extremely low flash point or boiling point. Besides, the gases catch fire in contact with air. What's more, it is one important basic chemical raw material that should be sealed in ventilated, cool room away from oxidants.
Physical properties about α-Butene are: (1)ACD/LogP: 2.34; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 2.337; (4)ACD/LogD (pH 7.4): 2.337; (5)ACD/BCF (pH 5.5): 35.149; (6)ACD/BCF (pH 7.4): 35.149; (7)ACD/KOC (pH 5.5): 444.817; (8)ACD/KOC (pH 7.4): 444.817; (9)#Freely Rotating Bonds: 1; (10)Index of Refraction: 1.371; (11)Molar Refractivity: 20.306 cm3; (12)Molar Volume: 89.656 cm3; (13)Surface Tension: 16.354 dyne/cm; (14)Density: 0.626 g/cm3; (15)Enthalpy of Vaporization: 22.07 kJ/mol; (16)Vapour Pressure: 2213.905 mmHg at 25 °C.
Preparation of α-Butene: it is separated from the C4 fractionis. It also can be prepared by reaction of trimethylsilyl-cis-2-buten. The reaction needs reagent THF at the temperature of 60 °C for 3 hours. The yield is about 100%.
Uses of α-Butene: it is used to produce 2,2,4-trichloro-1,1,1-trifluoro-hexane by reaction with 1,1,1-trichloro-2,2,2-trifluoro-ethane. The reaction occurs with reagents CuCl, CuCl2*H2O, ethanolamine and solvent 2-methyl-propan-2-ol at the temperature of 85 °C for 15 hours. The yield is about 62%.
When you are using this chemical, please be cautious about it. As a chemical, it is extremely flammable. During using it, keep away from sources of ignition and take precautionary measures against static discharges. Furthermore, keep container in a well-ventilated place.
