Diethyl mercury is a chemical compound from the group of organic mercury compounds .

Extraction and presentation

Diethylmercury can be obtained by reacting ethylmagnesium bromide with mercury (II) chloride .

${\displaystyle \mathrm {2\ C_{2}H_{5}MgBr+HgCl_{2}\longrightarrow Hg(C_{2}H_{5})_{2}+MgBr_{2}+MgCl_{2}} }$

Several other types of manufacture are known.

properties

Diethylmercury is an almost odorless, highly flammable liquid that is almost insoluble in water. It decomposes when heated and slowly when left in light.

safety instructions

Diethylmercury fumes form explosive mixtures with air. The substance is highly toxic (generally organotoxic, neurotoxic ). It can be assumed that it is well resorbed after oral and inhalation intake and after skin contact ( transdermal ).
