Bridged Alkaline Earth Metal Alkylphenates |
| 摘要 |
A bridged alkaline earth metal alkylphenate having reduced monomeric alkylphenol is prepared by reacting (a) a 4-alkylphenol, unsubstituted at the ortho positions, (b) an alkaline earth metal oxide or hydroxide, (c) a bridging agent comprising sulfur or a carbonyl compound of 1 to about 6, or to 4 or to 2, carbon atoms, and (d) a 2,6-dialkylphenol. The amount of the 2,6-dialkylphenol is 0.05 to 3 moles per 1 mole of the 4-alkylphenol; if there is a molar excess of the 2,6-dialkylphenol, then the excess is added after initial reaction. |

1. A process for preparing a bridged alkaline earth metal alkylphenate, comprising reacting:
(a) a 4-alkylphenol, unsubstituted at the ortho positions, (b) an alkaline earth metal oxide or hydroxide, (c) a bridging agent comprising sulfur or a carbonyl compound of 1 to about 6, or to 4 or to 2, carbon atoms, and (d) a 2,6-dialkylphenol;wherein amount of the 2,6-dialkylphenol is about 0.05 to about 3 moles (or about 0.1 to about 1.3 or about 0.25 to about 1.25 moles) per 1 mole of the 4-alkylphenol; provided that if there is a molar excess of the 2,6-dialkylphenol, then such excess is added after initial reaction of the 4-alkylphenol with alkaline earth oxide or hydroxide, the bridging agent, and no more than 1 mole of the 2,6-dialkylphenol per mole of the 4-alkylphenol. |
