Calcium hypochlorite is an inorganic compound with formula Ca(ClO)2. It is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for water treatment and as a bleaching agent. This compound is relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air. It is not highly soluble in hard water, and is more preferably used in soft to medium-hard water. It has two forms: dry (anhydrous); and hydrated (hydrous).
Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process. As a swimming pool chemical, it is blended with other chemicals less on than other forms of chlorine, due to dangerous reactions with some common pool chemicals. In solution, calcium hypochlorite could be used as a general purpose sanitizer, but due to calcium residue, sodium hypochlorite (bleach) is usually preferred.Organic chemistry
Calcium hypochlorite is a general oxidizing agent and therefore finds some use in organic chemistry. For instance the compound is used to cleave glycols, α-hydroxy carboxylic acids and keto acids to yield fragmented aldehydes or carboxylic acids. Calcium hypochlorite can also be used in the haloform reaction to manufacture chloroform.

α-Methylstyrene (AMS) is a chemical intermediate used in the manufacture of plasticizers, resins and polymers. It is a co-product formed in a variation of the cumene process. The homopolymer obtained from this monomer, poly(α-methylstyrene), is unstable, being characterized by a low ceiling temperature.Uses
Alpha-methylstyrene (AMS) is a colourless liquid used as a co-monomer in a range of polymerisation processes to improve impact and heat resistance. In many applications of this kind it competes with styrene, over which it has some stability and handling advantages. It can be copolymerised with monomers such as benzene, acrylates and styrene. The primary use of AMS is in acrylonitrile-butadiene-styrene (ABS) resins, which account for around a third of demand. In ABS resins it prevents heat distortion. AMS has applications in a diverse range of products including perfumes, antioxidants, drying oils and lubricating oils. Other uses include the production of low molecular weight polymers, which form viscous liquids used in adhesives and coatings, waxes and plasticisers.
AMS is recovered as a by-product of the phenol production process of cumene oxidation. This can then be purified by continuous distillation under reduced pressure to lower the amount of phenol, cumene and butyl benzene impurities.
Because of the cost of this purification in limited markets, many phenol producers do not separate AMS but simply recycle it by hydrogenating it back to cumene. Companies such as UOP and Kellogg license the process. Another route used in the FSU involved dehydrogenation of cumene to AMS.Health and safety
AMS irritates the skin, eyes and throat. If burned it can release toxic gases and vapours such as carbon monoxide.
It is incompatible with strong oxidising agents, copper, mercury or alkaline pesticides.
