Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl4. It is a volatile, non-flammable, dense, colourless liquid with a chloroform-like sweet odour that can be detected at low levels. It was formerly widely used in fire extinguishers, as a precursor to refrigerants, an anthelmintic and a cleaning agent, but has since been phased out because of environmental and safety concerns. Exposure to high concentrations of carbon tetrachloride can affect the central nervous system and degenerate the liver and kidneys. Prolonged exposure can be fatal.

👉 Carbon tetrachloride in the context of Binary phase
In materials chemistry, a binary phase or binary compound is a chemical compound containing two different elements. Some binary phase compounds are molecular, e.g. carbon tetrachloride (CCl4). More typically binary phase refers to extended solids. Famous examples zinc sulfide, which contains zinc and sulfur, and tungsten carbide, which contains tungsten and carbon.
Phases with higher degrees of complexity feature more elements, e.g. three elements in ternary phases, four elements in quaternary phases. These phases exhibit a higher degree of complexity due to the interaction of these elements at different conditions.

Carbon tetrachloride in the context of Chloride
The term chloride refers to a compound or molecule that contains either a chlorine anion (Cl), which is a negatively charged chlorine atom, or a non-charged chlorine atom covalently bonded to the rest of the molecule by a single bond (−Cl). The pronunciation of the word "chloride" is /ˈklɔːraɪd/.
Chloride salts such as sodium chloride are often soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating liquid flow in and out of cells. Other examples of ionic chlorides include potassium chloride (KCl), calcium chloride (CaCl2), and ammonium chloride (NH4Cl). Examples of covalent chlorides include methyl chloride (CH3Cl), carbon tetrachloride (CCl4), sulfuryl chloride (SO2Cl2), and monochloramine (NH2Cl).

Michael Faraday (UK: /ˈfærəˌdeɪ/ FAR-uh-day, US: /ˈfærədi/ FAR-uh-dee; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. Although Faraday received little formal education, as a self-made man, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology. The SI unit of capacitance, the farad, is named after him.
As a chemist, Faraday discovered benzene and carbon tetrachloride, investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers, and popularised terminology such as "anode", "cathode", "electrode" and "ion". Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution, a lifetime position.

Dry cleaning is any cleaning process for clothing and textiles using a solvent other than water. Clothes are instead soaked in a water-free liquid organic solvent (usually non-polar, as opposed to water which is a polar solvent) typically inside a specialised dry-cleaning machine. The most commonly used solvent is Perchloroethylene (known as "PCE" or "perc" for short), although other solvents such as hydrocarbon mixtures and decamethylcyclopentasiloxane are also used. Historical solvents include carbon tetrachloride, trichloroethylene, trichlorotrifluoroethane, trichloroethane and n-propyl bromide.
Most natural fibers can be washed in water but some synthetics (e.g., rayon) react poorly with water and should be dry cleaned if possible. If not, this could result in changes in texture, colour, strength, and shape. Additionally, certain specialty fabrics, including silk, acetate and rayon, may also benefit from dry cleaning to prevent damage.
