Product Description

Chemicals Used In Paints 142-82-5 Heptane

Production methods:

1. Platinum reforming raffinate oil (93-102 ℃) fraction of n-heptane content of 57% or more, with 5A molecular sieve gas adsorption of n-alkanes, and then with steam desorption, separation of n-alkanes The Catalytic hydrogenation by nickel, so that a small amount of normal olefins saturated into n-alkanes, iodine value reduced to 0.1g iodine / 100g below qualified. And finally purified by the purity of 99.9% purity of the standard n-heptane. Industrial grade n-heptane purification can also be concentrated sulfuric acid washing, methanol azeotropic distillation and other methods. 2. Petroleum hydrocarbon fractions. May contain n-heptane, dimethylcyclopentane, 3-ethylpentane, methylcyclohexane and 3-methylcyclohexane. 3. Refining method In addition to containing boiling point similar to the alkane, naphthenic compounds, still contain unsaturated compounds, water and benzene. The benzene removal method is the same as that of hexane. Unsaturated hydrocarbons washed with concentrated sulfuric acid to remove, remove the water can be used calcium chloride, phosphorus pentoxide, sodium and potassium, etc., can also be used as a solid acid desiccant. And finally re-fractional refining
