Exempel på hur man kan använda CHLORINATION i en mening

• It is produced by chlorination of sucrose, selectively replacing three of the hydroxy groups—in the C1 and C6 positions of the fructose portion and the C4 position of the glucose portion—to give a 1,6-dichloro-1,6-dideoxyfructose–4-chloro-4-deoxygalactose disaccharide.
• This method proved to be too time-consuming, and, in 1915, the mint introduced a new chlorination process developed in Australia to reduce processing times and increase the mint's gold refining capacity.
• Silicon tetrachloride is prepared by the chlorination of various silicon compounds such as ferrosilicon, silicon carbide, or mixtures of silicon dioxide and carbon.
• Some, such as UK Company Brodex Water Treatment Specialists, advertise what services the company provides in the event of Legionella disease being discovered in a local supply, such as tank chlorination and equipment replacement.
• Major elements of the construction works still extant include the weir, a 10-cable cableway, shads, batching plants, roads, electrical substation, chlorination plant, maintenance staff accommodation, balance reservoir, Megarritys Bridge, water pumping station, tunnels, and associated pipelines.
• The water treatment steps include, in most cases, purification, disinfection through chlorination and sometimes fluoridation.
• However, the water in the pools was not being changed and water chlorination was unknown at the time, so the thermae and the unhygienic public toilets were source of diseases.
• SWG, a chlorine generator used in salt water chlorination, a way of sanitizing swimming pools by separating the chlorine ions (Cl-) from salt (NaCl).
• Chloroprene is produced in three steps from 1,3-butadiene: (i) chlorination, (ii) isomerization of part of the product stream, and (iii) dehydrochlorination of 3,4-dichlorobut-1-ene.
• In synthetic chemistry, two classes of chlorination are usually of interest: oxidative chlorinations and substitutive chlorinations.
• The chlorination reaction can be conducted in the presence of tetrabutylammonium chloride, the product being the lipophilic salt tetrabutylammonium tetrachloraurate.
• The conversion can be effected with thionyl chloride: It also can be prepared by chlorination of niobium pentoxide in the presence of carbon at 300 °C.
• Chloral is produced commercially by the chlorination of acetaldehyde in the presence of hydrochloric acid, producing chloral hydrate.
• A typical representative organic reaction displaying this mechanism is the chlorination of alcohols with thionyl chloride, or the decomposition of alkyl chloroformates, the main feature is retention of stereochemical configuration.
• New treatment facilities included pre-treatment, filtration, chlorination, stabilisation and fluoridation.
• Thus, sulfur dichloride, disulfur dichloride, and higher chlorosulfanes arise from the chlorination of sulfur.
• Early industrial methods started from furfural and later by the chlorination of butadiene to give 1,4-dichloro-2-butene, which with sodium cyanide, converts to 3-hexenedinitrile, which in turn can be hydrogenated to adiponitrile:.
• Although the city water system uses chlorination as a basic disinfection technology, the ultraviolet disinfection (UV) facility was built to control microorganisms such as giardia and cryptosporidium which are resistant to chlorine treatment.
• Chlorothalonil can be produced by the direct chlorination of isophthalonitrile or by dehydration of tetrachloroisophthaloyl amide with phosphoryl chloride.
• The sewage treatment plant includes primary-secondary treatment and the following advanced wastewater treatment processes: chemical clarification, two-stage recarbonation with intermediate settling, multimedia filtration, granular activated carbon adsorption, chlorination for disinfection and dechlorination.
