text: Another batch of grease was made using the same equipment, raw materials, amounts, and manufacturing process as the Example 1 grease, except that the calcium carbonate was added immediately after conversion but before the complexing acids (12-hydroxystearic acid, acetic acid, and phosphoric acid) were added.
text: In this prior art grease, calcium carbonate was added before conversion, but calcium hydroxide was also added in sufficient amount after conversion to fully react with all the complexing acids added thereafter.
text: Although the penetrations of the Example 5 and 6 greases were comparable, the dropping point of the Example 6 grease where the calcium carbonate was added after conversion was nearly 200 F lower than the Example 5 grease where the calcium carbonate was added pre-conversion.
text: Summarizing thus far, these first seven examples taken together strongly demonstrate the following: (1) overbased calcium sulfonate-based greases can be prepared using calcium carbonate as the only added calcium-containing base for reaction with complexing acids; (2) use of calcium carbonate added pre-conversion provides superior greases compared to when the calcium carbonate is added post-conversion, even when this is the only difference between the two greases; (3) adding calcium carbonate before conversion as the sole added calcium-containing base provides superior greases compared to prior art greases where calcium carbonate was not added and calcium hydroxide was added after conversion; (4) adding calcium carbonate before conversion as the sole added calcium-containing base provides superior greases compared to prior art greases where calcium carbonate is added before conversion but calcium hydroxide is added after conversion for reaction with complexing acids; (5) adding calcium carbonate before conversion as the sole added calcium-containing base provides superior greases compared to greases where calcium hydroxide is added before conversion for reaction with complexing acids, and calcium carbonate is added after conversion and after reaction with the complexing acids.
text: Thus, adding calcium carbonate before conversion according to a preferred embodiment of the invention provides a superior product to the same composition if the calcium carbonate is added after conversion.
text: This demonstrates that forming a simple calcium sulfonate grease with added calcium carbonate present before conversion provides a superior simple grease composition to one where calcium carbonate is added after conversion.
text: In the Example 4 grease, when the calcium carbonate was added after conversion and after the addition of the three complexing acids, the grease was softer than the Example 1 grease by 52 points, and the dropping point was also significantly lowered.
text: Another batch of grease was made using the same equipment, raw materials, amounts, and manufacturing process as the Example 5 grease, except that the calcium carbonate was added immediately after conversion but before the 12-hydroxystearic acid, acetic acid, and phosphoric acid were added.
