Atrazine was invented in 1958 in the Geigy laboratories as the second of a series of 1,3,5-triazines. [26] Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropylamine. Like other triazine herbicides, atrazine functions by binding to the plastoquinone-binding protein in photosystem II, which ...

Strong salts or strong electrolyte salts are chemical salts composed of strong electrolytes. These salts dissociate completely or almost completely in water. They are generally odorless and nonvolatile. Strong salts start with Na__, K__, NH 4 __, or they end with __NO 3, __ClO 4, or __CH 3 COO. Most group 1 and 2 metals form strong salts.
Gallane liquid decomposes at 0 °C. Nitroxyl and diazene are simple nitrogen compounds known to be gases but they are too unstable and short lived to be condensed. Methanetellurol CH 3 TeH 25284-83-7 unstable at room temperature. [154] Sulfur pentafluoride isocyanide isomerises to sulfur pentafluoride cyanide. [155]
Cyanuric chloride is an organic compound with the formula (NCCl) 3. This white solid is the chlorinated derivative of 1,3,5-triazine. It is the trimer of cyanogen chloride. [1] Cyanuric chloride is the main precursor to the popular but controversial herbicide atrazine.
Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid , and molten salts are technically a class of ionic liquids.
Hydrazoic acid, also known as hydrogen azide, azic acid or azoimide, [2] is a compound with the chemical formula HN 3. [3] It is a colorless, volatile, and explosive liquid at room temperature and pressure. It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride. It was first isolated in 1890 by Theodor Curtius. [4]
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
