一般描述

1,2-二氯乙烷(二氯化乙烯,DCE)是一种溶剂。它是氯乙烯制造工业 (EDC-tar)产生的一种降解副产物。已在 鼠伤寒沙门氏菌 TA 1535 上检测了它的致突变活性。已研究过它对二氧化钛/二氧化硅(酸性催化剂)的催化降解作用。

应用

1,2-二氯乙烷(二氯化乙烯,DCE)可用于以下研究:
  • 作为 脱卤球藻毒素 195 培养基中的电子受体。
  • 在各种研究中用作氯代有机物的模型化合物。
  • 在制备 Cl 掺杂的少层 WS 2 或 MoS 2 背栅场效应晶体管(FET)过程中的化学掺杂。

Low-resistivity metal-semiconductor (M-S) contact is one of the urgent challenges in the research of 2D transition metal dichalcogenides (TMDs). Here, we report a chloride molecular doping technique which greatly reduces the contact resistance (Rc) in the few-layer WS2 and MoS2....

"Dehalococcoides ethenogenes" 195 can reductively dechlorinate tetrachloroethene (PCE) completely to ethene (ETH). When PCE-grown strain 195 was transferred (2% [vol/vol] inoculum) into growth medium amended with trichloroethene (TCE), cis-dichloroethene (DCE), 1,1-DCE, or 1,2-dichloroethane (DCA) as an electron acceptor, these chlorinated...
