Specification

The 1-Hexene is an organic compound with the formula C₆H₁₂. The IUPAC name of this chemical is hex-1-ene. With the CAS registry number 592-41-6, it is also named as Hexene. The product's categories are Industrial/Fine Chemicals; 1-Olefins (GC Standard); Analytical Chemistry; Standard Materials for GC; HA-HTGasoline, Diesel & Petroleum; Alpha Sort; E-LAlphabetic; H; Olefins; Substance Classes; Volatiles/ Semivolatiles; Acyclic; Alkenes; Organic Building Blocks. Besides, it is colourless liquid, which should be stored in a closed cool and dry place.

The primary use of 1-hexene is as a comonomer in production of polyethene. Another significant use of 1-hexene is the production of linear aldehyde via hydroformylation ( oxo synthesis ) for later production of the short-chain fatty acid heptanoic acid.

Physical properties about 1-Hexene are: (1)ACD/LogP: 3.36; (2)ACD/LogD (pH 5.5): 3.356; (3)ACD/LogD (pH 7.4): 3.356; (4)ACD/BCF (pH 5.5): 209.093; (5)ACD/BCF (pH 7.4): 209.093; (6)ACD/KOC (pH 5.5): 1594.066; (7)ACD/KOC (pH 7.4): 1594.066; (8)#Freely Rotating Bonds: 3; (9)Index of Refraction: 1.397; (10)Molar Refractivity: 29.571 cm³; (11)Molar Volume: 122.67 cm³; (12)Polarizability: 11.723×10^-24cm³; (13)Surface Tension: 20.139 dyne/cm; (14)Density: 0.686 g/cm³; (15)Enthalpy of Vaporization: 29.24 kJ/mol; (16)Boiling Point: 62.81 °C at 760 mmHg; (17)Vapour Pressure: 188.145 mmHg at 25°C.

Preparation: this chemical can be prepared by ethene. This reaction will need reagent methylaluminoxane, catalyst tridentate PNP Cr(III) complex. The reaction time is 30 min with reaction temperature of 80 °C. The yield is about 100%.

Uses of 1-Hexene: it can be used to produce hex-1-en-3-one at temperature of 55 °C. It will need reagent HgSO₄ and diluted H₂SO₄.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. If swallowed, do not induce vomiting: seek medical advice immediately and show this container or label.
