Mixed bromine/chlorine transformation products (Cl y Br x BPAs) of tetrabromobisphenol A (TBBPA) were recently identified for the first time in an electronic waste (e-waste) dismantling site. To determine whether these compounds can be used as specific molecular markers of e-waste dismantling ...
In the present study, debromination and unknown mixed bromine/chlorine transformation products of TBBPA (X-BBPA) were screened in dust samples from an e-waste dismantling site. Five mono-chloro products (2-chloro-2',6,6'-TriBBPA, 2-chloro-2',6-DiBBPA, 2-chloro-2',6'-DiBBPA, 2-...
9. The average relativeerror was 3.63%, less much than mostly used group-contribution methods for alkyne, chlorine derivative, iodine derivative, especially for alkane, bromine derivative, aromatic hydrocarbon, alicyclic hydrocarbon and sulfur-containing organic compounds. ...

Chlorine often imparts many desired properties in an organic compound when it is substituted for hydrogen (synthetic rubber), so it is widely use in organic chemistry, in the production of chlorates, chloroform, carbon tetrachloride, and in the bromine extraction. Chlorine in the environment In...
bromine. Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution. In fact, chlorine was used as a war gas in 1915 as a choking (pulmonary) agent. Chlorine itself is not flammable, but it can react explosively or form explosive compounds with other ...
Tin was determined gravimetrically as the oxide, and chlorine, bromine, and iodine were determined by potentiometric titration with silver(I) nitrate. ... WA Gustavson,LM Principe,WZM Rhee,... - 《Journal of the American Chemical Society》 被引量: 31发表: 1981年 Mixed sodium, ammonium and/...
Since the onset of ozone depletion in the 1980s, however, human activities have continued to alter atmospheric composition through the increased emissions of a variety of chemical species in addition to those containing chlorine and bromine. 然而,自1980年代发现臭氧消耗问题以来,人为活动继续因除含有氯...
(the electronegativity of fluorine is 3.98, the electronegativity of chlorine is: 3.16, the electronegativity of bromine is 2.96, and the electronegativity of iodine is 2.66). this element is less reactive than fluorine and more reactive than bromine, in line with periodic patterns. even though ...
