Not to confuse with cacodyl, a poisonous, oily, flammable liquid which contains arsenic and smells like garlic.
Early in his career Bunsen did research in organic chemistry, which cost him the use of his right eye when an arsenic compound, cacodyl cyanide, exploded.
In 1858, in Berlin, he received his doctorate for his work on cacodyl compounds which had been done in Kekulé's laboratory.
Simultaneously with his work on cacodyl, he was studying the composition of the gases given off from blast furnaces.
The first research by which attention was drawn to Bunsen's abilities was concerned with the cacodyl compounds (see ARSENIC), though he had already, in 1834, discovered the virtues of freshly precipitated hydrated ferric oxide as an antidote to arsenical poisoning.
"After that accident I believe the work on cacodyl oxide and phosgene was suspended and I believe that work was carried out on chlorine or chlorine compounds."
Reliable authority exists for the statement that soon after this date they were working with cacodyl oxide and phosgene, both well known before the war for their very poisonous nature, for use, it was believed, in hand grenades.
German chemist, combined oxide of cacodyl with cyanogen, a radical of prussic acid, producing cyanide of cacodyl, or diniethyl arsine cyanide.
It is cyanide of cacodyl, and I have carried that small flask of it about with me for months.
As he crossed the room some evil chance made him think of the gossip outside and of his allusion to the abstruse substance known as cacodyl.
