Tetrachloride

Carbon tetrachloride, also known by many other names (see table) is the organic compound with the formula ccl4. It is a reagent in synthetic chemistry and was formerly widely used in fire extinguishers, as a precursor to refrigerants, and as a cleaning agent. It is a colourless liquid with a "sweet" smell that can be detected at low levels.

Silicon tetrachloride is a non-polar chemical compound with the formula SiCl4. It was prepared by Jöns Jakob Berzelius in 1823.

Causes severe irritation and burns. May Be harmful if swallowed. Avoid breathing vapor or dust. Use with adequate ventilation. Avoid contact with eyes, skin, and clothes. Wash thoroughly after handling. Keep container closed.

Titanium tetrachloride is the inorganic compound with the formula TiCl4. It is an important intermediate in the production of titanium metal and the pigment titanium dioxide. TiCl4 is an unusual example of a metal halide that is highly volatile. Upon contact with humid air, it forms spectacular opaque clouds of titanium dioxide (TiO2) and hydrogen chloride (HCl)

Zirconium(iv) chloride, also known as zirconium tetrachloride, is the inorganic compound with the formula zrcl4. This white high-melting solid hydrolyzes rapidly in humid air. It is a key precursor to other compounds of zirconium.
