Colorless liquid with fruity fragrance. Relative density (20°C/4°C) 0.8825, freezing point -73.5°C, boiling point 126.11°C, flash point (open) 33°C, ignition point 421°C, refractive index 1.3941, specific heat capacity (20°C) 1. 91KJ/(kg·K), viscosity (20°C) 0.734mPas, solubility parameter δ=8.5. Soluble in alcohol, ketone, ether and other organic solvents, slightly soluble in water. In case of high heat, open flame and oxidant, it may cause burning hazard. Vapor and air form an explosive mixture with an explosion limit of 1.4%-8.0% (vol). Low toxicity, anesthesia and irritation, the maximum allowable concentration in the air is 300mg/m3 (or 0.015%).

Uses: used in collodion, nitrocellulose, varnish, artificial leather, medicine, plastics and fragrance industries. It is an excellent organic solvent that can dissolve rosin, polyvinyl acetate, polyacrylate, polyvinyl chloride, chlorinated rubber , Eucommia gum, polymethyl methacrylate, etc.
