Paraffin Crystal Wax CAS 8002-74-2
Hunan zirconium iron import and export Co., Ltd is a professional research, development and production of zirconium silicate & titanium dioxide backbone members of enterprise, the local well-known entrepreneurs and professional senior engineers in the party′s call for "safety and smoothness low carbon environmental protection" and the support of the bold innovation on traditional production equipment and technology, on the basis of reducing the product cost make the product quality to achieve the same industry leading level.
Paraffin, also known as crystalline wax, is a kind of non-polar solvent soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha, etc., insoluble in polar solvents such as water and methanol .
A mixture of hydrocarbons with a carbon number of about 18 to 30, the main components are straight-chain alkanes (about 80% to 95%), and a small amount of alkanes with individual branched chains and monocyclic cycloalkanes with long side chains ( The total content of the two is less than 20%). Paraffin wax is obtained by solvent refining, solvent dewaxing, or freezing crystallization of wax, dewaxing by pressing, and dewaxing from the lubricating oil fraction obtained by crude oil distillation. According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
