Zinc Alkyl Dithiophosphate
Zinc alkyl dithiophosphates, also known as ZDDP, are very good antiwear agents that are often used as machine lubricants in many industries, including the automobile industry. In the 1940s, scientists came up with these coordination compounds, which are made of zinc joined to the anion of a dialkyldithiophosphoric acid. ZDDP is usually a dark, thick liquid with a mild smell. It doesn’t mix with water, even though it’s slightly less dense than water. Even though they are slightly to fairly soluble in water, their real use is as adds to rubbing oils.
