white powder. Melting point 248 °c (decomposition). The solubility in water is 790g/L at 0 ℃, which is soluble in ethanol and ethylene glycol. It is easy to decompose and release oxygen when heated to above 300 ℃. In neutral or weak alkaline solution, the oxidation ability is low, but in acidic solution or in the presence of induced oxidant and catalyst, it is a strong oxidant. The action with acids releases chlorine dioxide. Mixing with sulfur, phosphorus and organic matter or being impacted is susceptible to combustion and explosion. Corrosive to zinc and carbon steel. Deliquescence, high humidity in the air can absorb water vapor solution.
It can be obtained by electrolysis of a concentrated acid solution of sodium chloride at 80 to 90 °c.
killing herbicides. Widely used in non-cultivated land and reclamation of wild land when the killing of weeds. A variety of plants can be killed, the Compositae, Gramineae plants have root effect, the deep-rooted perennial grass weed effect is remarkable. All green plants have strong Phytotoxicity, plant roots and stems have a role in its absorption. In general, the application of medicine in the period of vigorous plant growth depends on the type, quantity and size of weeds. Spraying with water or directly spraying powder, can be mixed with residual organic herbicides such as herbicide, grass, grass, grass, grass, and so on.
Acute Oral LDso in rats: 1.2g/kg; LDso in human: 15-20g/kg. Dust can irritate the skin, mucous membranes and eyes. Staff should be protected. If sodium chlorate is accidentally sprayed into the eyes or on the skin, it should be immediately rinsed with plenty of water. The workshop should be well ventilated.
