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.

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period uut it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
