Methylenebis(dibutyldithiocarbamate)
Methylenebis(dibutyldithiocarbamate) is the organosulfur compound with the formula CH2(SC(S)NBu2)2 (Bu = C4H9). It is a derivative of dibutyldithiocarbamate that is used as an additive to various lubricants, both as an antioxidant and to prevent metal surfaces.[1] It is prepared by alkylation of the dithiocarbamate with dichloromethane.[2] Although it is described as colored, simple esters of dithiocarbamate are typically colorless.[3]
