Ethyl acetate (Class III hazardous material)
Colorless clarified liquid with aromatic odor, volatile. Melting point (℃): -83.6, boiling point (℃): 77.2, density (water = 1): 0.90 (20 ℃, slightly soluble in water, soluble in ethanol, acetone, ethyl ether, chloroform, benzene and most other organic solvents. Highly flammable.
Ethyl benzoate (Class III hazardous material)
Colorless transparent liquid, with ylang ylang-like floral and fruity aroma, the aroma is milder than methyl benzoate. Melting point (ºC): -34, Boiling point (ºC): 211~214, Density (d204): 1.05 (20°C.). Slightly soluble in water, soluble in ethanol and ether.
Monochloromethane (Class VI Hazardous Chemicals)
It is a colorless flammable toxic gas, slightly soluble in water, easily soluble in ether, benzene and so on. It is flammable and can form explosive mixture with air. Chloromethane is hydrolyzed above 60℃ to form methanol.
Dichloromethane (six types of hazardous chemicals)
Colorless transparent liquid with aromatic odor, melting point (℃): -95, boiling point (℃): 39.8, density (water = 1): 1.33, slightly soluble in water, soluble in ethanol, ether.
Trichloromethane (Class VI Hazardous Chemicals)
Colorless transparent heavy liquid, very volatile, with special odor. Melting point (℃): -63.5, boiling point (℃): 61.3, density (water = 1): 1.50, insoluble in water, soluble in alcohol, ether, benzene
Epichlorohydrin (Class III Hazardous Chemicals)
Colorless transparent low boiling flammable liquid at room temperature and pressure, with ether-like odor, low boiling point, flammable, melting point: -112 °C, boiling point: 34 °C, density: 0.830 g/cm3 (20 °C). Partially miscible with water, miscible with ethanol and ether.
Epichlorohydrin (Class III Hazardous Chemicals)
Colorless oily liquid, with chloroform irritating odor, similar to the irritating odor of garlic, melting point: -25.6 °C, boiling point: 117.9 °C, density (water=1) 1.18 (20 °C).
