    摘要: The present invention provides a grease composition including a thickener and a base oil, in which the thickener is a urea compound represented by the following formula (1) R1—NHCONH—R2—NHCONH—R3   (1) wherein R2 represents a divalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and R1 and R3 may be the same or different and each represent an alkyl group having 8 to 22 carbon atoms, a cyclohexyl group, or an aryl group having 6 to 12 carbon atoms, and as the base oil, one or more types of a compound represented by the following formula (2) are contained at 40% by mass or more relative to a total mass of the base oil wherein R4 and R5 may be the same or different and each represent a linear or branched alkyl group having 10 to 26 carbon atoms, where m and n are real numbers being 0 or more which satisfy m+n=2.

    摘要: This disclosure relates to a continuous process for preparing a grease thickener product in which operating conditions of the continuous process can be varied to obtain desired grease product properties. The process includes: (a) introducing a C3 to C30 hydroxy fatty acid or a C3 to C30 hydroxy fatty acid ester, and a metal base into a reaction zone; (b) operating the reaction zone at a temperature between 100° C. and 240° C. to react the C3 to C30 hydroxy fatty acid or the C3 to C30 hydroxy fatty acid ester, and the metal base, to produce a grease thickener product; (c) introducing the grease thickener product of step (b) into a flash chamber zone; and (d) operating the flash chamber zone at a temperature sufficient to remove volatiles from the grease thickener product of step (b). The continuous process conditions afford a production throughput of grease thickener product of greater than 8,000 pounds per hour.
