HHM H68 DIPHENYL Application
1. Mainly used for Heat Transfer oil. 26.5% HHM68+73.5% HHM 28 can be HHM H400, which  may serve as liquid phase organic thermal carrier, and it may also be used as gas phase organic thermal carrier by utilizing its evaporation-condensation properties, so it is the top choice organic thermal carrier to be used for 12℃～400℃ liquid phase heating system or 257℃～400℃ gas phase heating system.
2.Used in the production of flavoring.
3. Used in the production of Decabromodiphenyl oxide.
4.  4. Used in production of synthetic resin and other organic synthesis.
HHM H28--DIPHENYL OXIDE Production method
Phenol potassium and chlorobenzene in the role of catalyst copper powder, after pressure combined heating, cooling, separation, and then to vacuum distillation.

HHM H28--DIPHENYL OXIDE First Aid Measures
【Ingestion】Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
【Inhalation】Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
【Skin】Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
【Eyes】Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. 
HHM H28--DIPHENYL OXIDE Fire Fighting Measures 　
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Extinguishing media: Water spray may cause frothing. In case of fire, use carbon dioxide, dry chemical, or water fog. Solid streams of water may spread fire.
