Double displacement reactions can be used to prepare sulfones (R2SO2) and sulfoxides (R2SO) by treating thionyl chloride (SOCl2) or sulfuryl dichloride (SO2Cl2) with an alkyllithium or a Grignard reagent.
In combination with chlorine it yields sulfur chlorides such as disulfur dichloride, S2Cl2, a corrosive, golden-yellow liquid used in the manufacture of chemical products.
Only a few compounds of neodymium in the +2 state have been prepared, such as the diiodide NdI2 and the dichloride NdCl2; the Nd2+ ion is unstable in aqueous solution.
The English chemist Henry Enfield Roscoe first isolated the metal by hydrogen reduction of vanadium dichloride in 1867, and the American chemists John Wesley Marden and Malcolm N. Rich obtained vanadium of 99.7 percent purity by a calcium reduction process in 1925.
This removal was achieved by the addition of small quantities of a scavenger, ethylene dibromide, often in a mixture with ethylene dichloride.
A unique synthesis of sulfides is illustrated by the reaction of ethylene with sulfur dichloride to form bis β-chloroethyl) sulfide, known as sulfur mustard, or mustard gas, a bis β-chloroethylvesulfide chemical warfare agent.
A compound of ytterbium in the +2 oxidation state was first prepared in 1929 by W.K. Klemm and W. Schuth, who reduced ytterbium trichloride, YbCl3, to ytterbium dichloride, YbCl2, with hydrogen.
The product depends on the chloridizing reaction taking place, with magnesium dichloride, for example, forming as a watery liquid and titanium tetrachloride coming off as a gas.
It is potassium dichromate, not potassium dichloride.
He was fearless and careful, a good fit for his hazardous job fitting and repairing pipes carrying lethal chemicals such as ethylene dichloride, mercury, lead, chromium, polycyclic aromatic hydrocarbons, and dioxins.
Radium-223 dichloride, marketed as Xofigo, could be made available for treating prostate cancer patients as early as December.
