Application Areas
Organic solvents: Due to their good lipid solubility and chemical inertness, they can be used as non-polar organic solvents to dissolve hydrophobic substances such as oils, waxes, resins, and rubber. They are suitable for extraction, cleaning, or dilution processes in fine chemicals (such as coating diluents and precision instrument cleaning agents).
Fuel and fuel additives: 2,5-dimethylheptane can be used as a model compound to study the combustion characteristics of branched alkanes, such as combustion efficiency and detonation performance, providing data support for fuel formulation optimization; It can also be used as a fuel additive to improve the fluidity or stability of fuel.
Chemical synthesis raw materials: Under high temperature or catalyst conditions, dehydrogenation, halogenation and other reactions can occur, which are used to synthesize intermediates such as olefins and halogenated alkanes, and further prepare fragrances, lubricants or surfactants.
Storage conditions
Conventional conditions: It is recommended to store in a cool, dry, well ventilated warehouse and avoid direct sunlight.
Special requirement: It needs to be stored separately from oxidants, acids, bases, etc. to prevent chemical reactions. Containers need to be leak proof, it is recommended to use leak proof trays to reduce environmental risks
Safety precautions
Health hazards:
Skin contact: May cause irritation, rinse immediately with clean water.
Inhalation/ingestion: Quickly transfer to fresh air and seek medical attention if necessary.
Leakage handling:
Small leakage: Absorb with inert materials (such as sand, activated carbon) and collect in a closed container
Massive leakage: Wear protective equipment to prevent the leaked material from entering water bodies or sewers.
Firefighting measures:
Extinguishing agent: dry powder, foam or carbon dioxide, avoid direct water fire extinguishing
