| Overview | hydrogenated Terphenyl is a heat carrier used in high temperature liquid phase, which is a partially hydrogenated Terphenyl product with good thermal stability, the liquid phase has the advantages of high use temperature, low freezing point (<-25 ° C), fraction weight (330 ° C -420 ° C), low vapor pressure, low operating pressure when the liquid phase is used. It is widely used in the fields of synthetic fiber, synthetic resin, medicine and petrochemical industry. Long-term operation of hydrogenated terphenyls at high temperature, will produce thermal cracking, condensation polymerization and coking process, cracking to produce low boiling components and high boiling components, resulting in decreased flash point, carbon residue and acid value increase, prone to explosion, corrosion of equipment, Coke, etc., affecting the normal operation of the equipment. Therefore, the hydrogenated Terphenyl must be replaced or regenerated in a timely manner. At present, the use of simple fractionation treatment method, because some azeotrope is difficult to remove, and thus after the treatment of hydrogenated carbon and acid value still can not meet the requirements. |
| Application | hydrogenated Terphenyl is a kind of heat transfer oil with excellent performance, and its main component is a mixture of some hydrogenated Terphenyl isomers, it is obtained by partial hydrogenation of a mixture of O-, m-and p-terphenyls in different proportions (saturation of 39%). Hydrogenated Terphenyl has excellent thermal stability, oxidation resistance and low vapor pressure characteristics, it is widely used in petrochemical, synthetic fiber, synthetic resin, medicine, printing and dyeing and other industries, high temperature heat conduction, heating equipment system, chemical Fiber polymerization (polyester, nylon polymerization, dry spandex spinning), Silicone Monomer synthesis, trichlorosilane and polysilicon, pharmaceuticals, pesticides, dye intermediates and other fine chemicals, biodiesel. |
