The higher mercaptans could be just what you need to get the surface effects you've been looking for. And we make them up through C18. The higher mercaptans give you a dual advantage. The presence of a long chain hydrocarbon group plus a reactive thiol radical can lead to interesting surface qualities. One of our newest success stories! In the froth flotation of copper ore, higher mercaptans pay off with a big boost in metal ^ ^ 5 Π Ρ recovery. |£2l It Biodegradabiiity is another plus. ExCHEMIC tensive field data indicate that comHEA

pounds based on mercaptans show biodegradable properties. And with the other talents they have, you'll also find them highly useful in agricultural and indus­ trial biocides, in pharmaceuticals, as antioxidants, in a wide range of syntheses.
