摘要： The invention pertains to chlorine-free extreme pressure metalworking fluid additives and lies in the recognition of the improved hydrolytic stability of alkanoic acid esters of cyclohexane dimethanol and other esters embodying similar structures. The various derivatives which are effective as extreme pressure additives include those which fall within the generic description ##STR1## wherein R.sup.1 through R.sup.4 are independently selected from the group hydrogen and C.sub.1-24 hydrocarbyl groups and R.sup.5 and R.sup.6 are independently selected from the group C.sub.3-24 hydrocarbyl groups.
