Abstract
Amine salts having utility in metalworking operations is disclosed. The amine salts are prepared by the reaction of (A) a dihydrocarbyldithiophosphoric acid of the formula ##STR1## wherein R.sup.1 and R.sup.2 are hydrocarbyl-based groups independently containing from about 5 to about 30 carbon atoms, X is oxygen or sulfur, and (B) an alkoxylated amine prepared by reacting a non-tertiary amine comprising (a) a monoamine, (b) a diamine, or (c) a polyamine, with from about 2 up to about 15 moles of an alkylene oxide comprising ethylene oxide or propylene oxide.
Claims19
A metal working composition, consisting essentially of:
- an amine salt blended in an oil, wherein the amine salt comprises the reaction product of
- (A) a dihydrocarbyldithiophosphoric acid of the formula ##STR19## wherein R.sup.1 and R.sup.2 are hydrocarbyl-based groups independently containing from about 5 to about 30 carbon atoms, X is oxygen or sulfur, and
- (B) an alkoxylated monoamine, diamine, or polyamine, wherein the alkoxylated amine contains from about 5 to about 15 moles of an alkylene oxide.
A metal working composition, consisting essentially of:
- an amine salt wherein the amine salt comprises the reaction product of
- (A) a dihydrocarbyldithiophosphoric acid of the formula ##STR22## wherein R.sup.1 and R.sup.2 are hydrocarbyl-based groups independently containing from about 5 to about 30 carbon atoms, X is oxygen or sulfur, and
- (B) an alkoxylated monoamine, wherein the alkoxylated monoamine contains from about 5 to about 15 moles of an alkylene oxide.
An additive concentrate comprising a substantially inert, normally liquid organic diluent and from about 5 percent to about 90 percent by weight of an amine salt, wherein the amine salt comprises the reaction product of
- A) a dihydrocarbyldithiophosphoric acid of the formula ##STR24## wherein R.sup.1 and R.sup.2 are hydrocarbyl-based groups independently containing from about 5 to about 30 carbon atoms, X is oxygen or sulfur, and
- B) an alkoxylated monoamine, diamine, or polyamine, wherein the alkoxylated amine contains from about 5 to about 15 moles of an alkylene oxide.
