  • Uses3
    • Plasticizer: It is a plasticizer with strong dissolving power for various resins, and can be compatible with various cellulose resins, rubbers, and vinyl resins. It is often used together with diethyl phthalate in the production of cellulose acetate films, varnishes, transparent papers, and molding powders. It can also be used as a plasticizer for nitrile rubber.
    • Solvent: It can be used as a solvent for mosquito - repellent oil (crude oil), polyvinyl fluoride coatings, methyl ethyl ketone peroxide, and DDT.
    • Other Fields: It is mainly used as a solvent and thickener in medicine and cosmetics, and can also be used as a penetration enhancer for some drugs. It can also be used as a carrier or diluent in the production of dyes and coatings.
  • Storage and Transportation: It is sensitive to light, so it should be stored in a cool, dry and ventilated place, and isolated from substances that are incompatible with it3. During transportation, it should be in accordance with the relevant regulations for hazardous chemicals, avoiding collision and high - temperature environment.
  • Safety Information3: It is corrosive and can cause serious damage to eyes and tissues after long - term contact. Its vapor has an anesthetic effect, which may cause symptoms such as headache, fatigue, dizziness and nausea. Inhalation, skin contact or ingestion will cause harm to the human body. When using, personal protection should be paid attention to, and protective equipment such as goggles and gloves should be worn, and the operation should be carried out in a well - ventilated environment.
