Sulfole® 120 T-Dodecyl Mercaptan is used in lubricant intermediates to produce additives as well as final components to improve lubricant performance in base oils and metal working fluids.
Sulfole® 120 mercaptan is a mixture of tertiary mercaptans, predominantly tertiary dodecyl mercaptan (thus the source for its acronym TDM). This product contains highly branched C12H25 alkyl mercaptan isomers, produced by the addition of hydrogen sulfide to propylene tetramer. It is used as a chemical intermediate to introduce bulky C12H25 alkyl-thio substituents into chemical substances. Its major use is as a chain transfer agent to control molecular weight of polymeric systems undergoing free-radical polymerization.

Sulfolane 120 (+b) TDM is a main component to produce metallic decoration (inks) for food packaging (porcelain, ceramics glass). It is also a lubricant additive used to improve lubricant performance in base oils and metal working fluids. Last but not least, it is a chain transfer agent in process where control of molecular weigh is critical from Polymer Modifiers in paint and coatings for emulsion polymerization, adhesives (pressure sensitive adh. for labeling) and surfactants & emulsifiers.
