CAS-89-8

nature : volatile and unstable colorless, oily liquid that smells like chloroform. Toxic. -25.6 ° C melting point, boiling point, 116.11 ° C and 98.0 ° C (53.3kPa), 79.3 ° C (26.7kPa), 62.0 ° C (13.3kPa), 42.0 ° C (5. 33kPa) and 16.6 ° C (1.33kPa.Conclusion), -16.5 ° C (0.05), the freezing point -57.2 ° C, the vapor pressure (20 ° C) 1.666kPa, viscosity (28 ° C) 1.03mPa s, the relative density of 1.1812 (20 / 4 ° C), the refractive index of 1.4382, flash point (open cup) 40.6 ° C spontaneous ° C415.6 points. With alcohol, ether, chloroform, three ethylene oxide, carbon tetrachloride Compatibility slightly soluble in water at 20 ° C, epichlorohydrin in the water solubility of 6.58% (quality). The formation of goods and water azeotrope, the boiling point for a total of 88 ° C, moisture content 28%. Combustion air Limit (volume%) 21.0 limit and the lower limit of 3.8. Epichlorohydrin molecular structure is asymmetric carbon atoms, generally containing L-and D-contour structure of the racemic mixture of form, with similar chloroform and ether odor.

Preparation : Industrial major propylene Preparation chloride. Propylene and chlorine to be heat - allyl chloride chlorine and hypochlorous again by the system of admission dichloro-propanol, thereby saponification obtained epichlorohydrin. The consumption of raw materials fixed : propylene (100%) input / t, sodium hydroxide (100%) wa s 150kg / t, chlorine 2070kg / t, vice-D-D mixture 140kg / t, calcium hydroxide (100%) 1020kg / t.
