权利要求: 1. A detergent comprising the reaction product of: (a) a mixture of about 25% to 80% by weight of anacardic acid, cardol, and cardanol; (b) a metal oxide or hydrated equivalent, selected from Magnesium Oxide, Calcium Oxide, or mixtures thereof or metal hydroxide, selected from Magnesium Hydroxide, Calcium Hydroxide, or mixtures thereof; (c) carbon dioxide.2. The detergent of claim 1, wherein the metal oxide comprises or consists of Magnesium Oxide.3. The detergent of claim 1, wherein the metal oxide comprises or consists of Calcium Oxide.4. The detergent of claim 1, wherein the metal hydroxide comprises or consists of Magnesium Hydroxide.5. The detergent of claim 1, wherein the metal hydroxide comprises or consist of Calcium Hydroxide.6. The detergent of any of claims 1 to 5, wherein the mixture contains at least 70% to no more than 80% by weight anacardic acid.7. The detergent of any of claims 1 to 6, wherein the anacardic acid is substituted with a C12-C16 unsaturated hydrocarbyl group or a C12-C15 hydrocarbyl group.8. A lubricant composition comprising (i) an oil of lubricating viscosity and (ii) a detergent of claims 1 to 7.9. The lubricant composition of claim 8, further comprising a neutral or overbased metal salt of alkylsalicylic acid substituted at the 3 or 5 position with a hydrocarbyl group.10. A process for preparing an alkaline earth metal salt of a salicylic acid substituted at the 6 position with a hydrocarbyl group comprising: reacting, at a temperature of 70°C or less, a mixture containing raw cashew nut shell liquid and an alkaline earth metal oxide or alkaline earth metal hydroxide.11. The process of claim 10, wherein the mixture further contains carbon dioxide.12. The process of claim 10 or 11, wherein the raw cashew nut liquid comprises about 50% to 80% by weight anacardic acid.13. The process of any of claims 10 to 12, wherein the anacardic acid is substituted with a C12-C16 unsaturated hydrocarbyl group or a C12-C15 hydrocarbyl group.14. The process of any of claims 10 to 13, wherein the alkaline earth metal is selected from Magnesium, Calcium, or mixtures thereof.
