IODINE

Molecular formula : I2 Molecular weight: 253.8

Iodine is the basic material in synthesizing organic or inorganic iodide, and is the essencial element for human body, animal or plant. Widely used in phar-maceutical, agricultural, dyestuff , metallurgical, rubber synthesizing, national defense, high-tech in-dustry etc.

1. Iodine has strong germicidal and disinfection effect, mainly used in pharmaceutical industry :

Tincture of iodine: 5%-10% concentration of iodine dissolved in alcohol;

Iodine solution of potassium iodide dissolved in water: used in remedy for wound, costalitis, tonsilitis, chronic anhritis, fracture etc. Also used in finger disinfection by surgical workers, goiter, aneriosclerosis, chronic intoxication, sleeping medicine, substitue in dehumidifying plasm etc.

Potassium iodide, sodium iodide and compound iodine solution can be used to cure goitre, preparation prior to hypenhyroidism operation. Due to the less eRect of potassium iodide for hean, can also be used in remedy for heavy metal poisoning, teniary great pox.

Iodine has special resistance against radioelement, thus oil iodide can be contrast agent of X light. Iodine is also the antidotal agent for radiation.

Vegetables, fruits and crops sprayed with iodine solution (1 of 20000) can be prevented from worm-eaten, can grow rapidly with higher yield.

Silver iodide is used as the atomizing agent in anificial rain.

3. In dyestuff industry, iodine is the material to synthesize organic dyestuffs.

4. In lighting industry, tungsten-iodine lamps made from iodine give strong light. Indium iodide and thallium iodide are used to make coloful light lamps.

5. In food industry, sodium iodate can improve the quality of bread , potassium iodate can be additive in salt. Iodalbin added in feedstuffs can prevent against various diseasses.

6. Iodine is used in chemical industry as catalyzer, in chemical synthesizing industry , used to synthesize methane iodide, ethane iodide; In metallurgical industry, iodine is used to refine high purity metal tita- nium, cobalt, silicon and germanium.
