Abstract
Disclosed is composition useful for reducing the concentration of mercaptans in hydrocarbons comprising: (A) a first diazo component and (B) a second component comprising a nucleophilic acceptor. The composition can be added to hydrocarbons such as fuel oil to reduce mercaptans without increasing turbidity or color. Triethylene diamine and 1,2-epoxyhexadecane are disclosed to be exemplary diazo and nucleophilic acceptor components.
