Abstract
A phenol-free overbased alkaline earth metal carboxylate is obtained by reacting a cyclic ether alcohol, an alkaline earth metal hydroxide, a fatty carboxylic acid, carbon dioxide, an optional fatty alcohol, and an optional liquid hydrocarbon solvent or oil.
Claims25
A method of making a phenol-free overbased alkaline earth metal carboxylate comprising:
- a. providing and reacting the following to form a reaction mixture:
- i. cyclic ether alcohol,
- ii. alkaline earth metal hydroxide, and
- iii. optionally a hydrocarbon solvent or oil and
- b. heating the reaction mixture to a temperature of 250-280° F.,
- c. adding (iv) a fatty acid to the reaction mixture,
- d. adding (v) carbon dioxide to the reaction mixture, to produce the phenol-free overbased alkaline earth metal carboxylate and water, and
- e. distilling at a temperature of over 280 to 300° F. to remove residual water, wherein no phenol or compound containing a phenol group is present in the reaction mixture.
