IT has been shown that compounds containing reactive chlorine atoms, and in particular those possessing a Cl3C‐ group, show marked E.P. activity when blended in mineral oil. Bromine compounds have been shown to be superior in E.P. activity to analogous chlorine compounds. Tribrom‐thioacetals, analogous to the trichlor‐compounds already described, have been prepared and found to possess good E.P. activity when blended in mineral oil. Such compounds show E.P. properties of a similar order to those shown by the trichlor‐compounds, but are more expensive to prepare and are less stable than their chlorine analogues, undergoing decomposition if impure or on keeping for long periods or on excessive heating.
