Daqing E-shine Chemical Co,.LTD was established in 2003. After so many years hard working,we already grow up from a small factory into the the largest alkanes manufactuer in China ,and enjoy a highly,profoundly repuration wordwide . Daqing E-shine Chemical Co,.TLD was the founded in Daqing City , where is the China oil city . Only 2 kilometers from raw materials suppler , we successful adopt the pipeline as a approach to transport the raw materials .which not only could save the cost of raw materials , but also make our products much more competitive in term of quality and price . As the leading chemical corporation in China , our products as below : Extraction grade hexane n-hexane : 110-54-3 isohexane :107-83-5 cyclohexane ：110-82-7 n-heptane :142-82-5 Isoheptane : 31394-54-4 n-pentane :109-66-0 isopentane :78-78-4 cyclopentane :287-92-3 solvent oil :68513-03-1 EXXSOL D 40 EXXSOL D 80 EXXSOL D 85 EXXSOL D 95 EXXSOL D 110 Technique : “Double hydrodesulfurization de-aromatic”is our measure for making the products , which is also the only corporation in China adopt this meansure . This feature coud optimize technique , for different components of the unsaturated hydrocarbons, aromatic hydrocarbons, organic sulfur, chlorine, nitrogen and other impurities by hydrogenation refined below 1 PPM ,even without . The whole process without alkali process, product impurities is almost zero. We have a strong ,forceful technician team ,couple with strictly quality control and inspectation system . our products features without strong excitant odour, without residue, non-corrosive . In the long-term of practice ,Eshine Group ,in order to advance ideas and action, take the initiative to recognize and cultivate the market , creating a “Marketing plan” “services markting” and “ Regional market develop strategy”to expand in the market such as new ideas ,covering the establishment of nationwide market network, formed its own core competitiveness, Eshine Group advocate corporate culture is also productive business philosophy , emphasize that “ Today’s culture is tomorrow’s economy”,the system refined the “famous Chinese brand , building first-class enterprise”, “creating value for customers ,creating opportunities for employees,creating the benefit for the community” and the “dedication, teamwork , innovation ,”the core of values .
