Chlorine-containing chemicals

Chlorinated water. The oxidizing power of chlorine-containing chemicals keeps swimming pool watar free of disease-causing microorganisms. 

During Swern oxidations, adventitious HC1 may be present either due to the use of impure oxalyl chloride, or due to the hydrolysis of some chlorine-containing chemical, caused by employing wet DMSO. Adventitious HC1 may cause acid-induced side reactions on sensitive substrates.174,246... 

Outside the U.S.A. the pattern varies, with LLDPE capacity continuing to lag behind, despite rapid expansions. In western Europe, LDPE still represents over half and LLDPE only 12% of all polyethylene produced (8.8 Mt per annum in total) vinyl chloride production is about 5Mt per annum (cf. some 6Mt per annum in the U.S.A., despite environmental concern regarding chlorine-containing chemicals). 

Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), informally called dioxins , occur as companion compounds or impurities in a large number of bromine- and chlorine-containing chemicals. 

Hydrogen chloride, HCl, can get into the atmosphere by accidental releases of the gas from the reaction of reactive chlorine-containing chemicals, such as SiCl4, with atmospheric water ... 

Oxidative cleaning can be performed using chlorine-containing chemicals. For example, a water slurry of sodium dichloroisocyanurate (e.g. swimming pool chlorine), which has 63% available chlorine, can be used to scrub an oxide surface to remove hydrocarbon contamination. This combines mechanical scrubbing with oxidation and improves the cleaning actioa... 

Production of TCF-bleached pulp, in which bleaching takes place without chlorine-containing chemicals, began in 1997. 

Both the substitution with chlorine at C-20 and the oxidation at C-13 are well known artifacts in chlorophyll chemistry (6, 7,9) The introduction of a chlorine atom during the conversion of chlorophyll -RCl to its methylpheophorbide can be ruled out, because the product was obtained as well when any chlorine containing chemicals (chlorinatd hydrocarbons, hydrochloric acid, sodium chloride, etc) were omitted during the entire procedure ...
