Physical and Chemical Properties | The original drug is white or milky yellow lumpy or flaky solid with 1.41 relative density. Pure products m.p.86 ~ 88 ℃, industrial products are about 77 ℃. Soluble in benzene, xylene and other organic solvents, soluble in ethanol and petroleum, insoluble in water (0.1mg/L). Methoxychlor has heat resistance and oxidation resistance. It is more difficult to remove hydrogen chloride in alcohol-alkali solution than DDT, but it is easy to remove hydrogen chloride under the catalysis of heavy metal ions. |
