摘要： A polyalkylene glycol ether phosphate ester, or salt thereof, having the formula:

R w -P(O)(OH) 3-w (I)

wherein w is an integer from 1 to 3, and
R is an oil-soluble polyether moiety having the formula:

R¹X[(C x H 2x O) n (C y H 2y O) p ] m (II)

wherein R¹ is either an alkyl or an alkyl phenyl group having from 7 to 30 carbon atoms,
X is either O, S, or N
x is an integer from 2 to 4,
y is an integer from 6 to 30,
m is 1 when X is O or S and m is 2 when X is N,
n and p are such that the polyether moiety contains between 1 and 35% by weight of (C y H 2y O) units and between 35 and 80% by weight of (C x H 2x O) units, and the molecular weight of the polyalkylene glycol moiety is between 500 and 5000 is disclosed.
The phosphate ester can be prepared by reacting a polyether with a phosphating agent, e.g. phosphorus pentoxide and water. Lubricating oil compositions comprising the phosphate ester or salt thereof are also disclosed. The phosphate esters and salts thereof are useful as extreme pressure/anti-wear additives.
