common salt,sodium chloride- a white crystalline solid consisting mainly of sodium chloride (NaCl) gas- a fluid in the gaseous state having neither independent shape nor volume and being able to expand indefinitely halogen- any of five related nonmetallic elements (fluorine or chlorine or bromine ...
awhen chlorine is added to water, part of it evaporates into the air, causing the familiar odor, and the rest is present in water in the following forms:chlorine, hypochlorous acid, hydrochloric acid, hypochlorous anion, and chloride. 当氯增加到水时,一部分的它蒸发入空气,导致熟悉的气味,并且...
• An additive to enhance the yield of symmetrical biaryls via palladium chloride catalyzed homo-coupling of aryl boronic acids in the absence of ligands.• A chlorine source for the α-chlorination of ketones in the presence of LDA.• A reactant in the tosylation of alcohols and phenols...
Vinyl, otherwise known as polyvinyl chloride (PVC),can pose a danger to human health and the environment under extreme conditions. For instance, when it's burned in a high-temperature fire, some of its toxic components, such as chlorine gas and the carcinogen dioxin, are released into the ...
Chlorine is abundant in cells and biomolecules, yet the biology of chlorine oxidation and reduction is poorly understood. Some bacteria encode the enzyme chlorite dismutase (Cld), which detoxifies chlorite (ClO2−) by converting it to chloride (Cl−) and molecular oxygen (O2). Cld is highly...

Vinyl Chloride (the raw material for polyvinyl chloride or PVC) was produced in two ways, by reacting acetylene and chlorine together in a column in the presence of a catalyst, or by the cracking of EDC (ethylene dichloride) at high temperature in a furnace into vinyl chloride and hydrogen ...
or PVC—will have to be eliminated and replaced with more sustainable alternatives, saysImari Walker-Franklin, a research chemist whopublished a book with MIT Presson plastics earlier this year. PVC, which is often used to make pipes and other materials, breaks down into toxic chlorine-...
