<p>1,209,548. Salts of aminoamides. TEXACO DEVELOPMENT CORP. 13 Nov., 1968, No. 53729/68. Heading C2C. [Also in Division C5] The invention comprises a salt reaction product of (A) a paraffinic oil oxidate, having a Neutralization No. of 55-80 and a Saponification No. of 100-200, said oxidate being derived from a paraffinic lubricating oil having an S.U.S. viscosity at 100‹ F. of 90-350 and a pour-point less than 10‹ F. and (B) an amide of the general formula in which R is a monounsaturated hydrocarbyl radical from oleic acid having 17 C atoms and R<SP>1</SP> and R<SP>11</SP> are alternately H and a C 14-18 hydrocarbyl radical, the ratio of the oxidate to amide being 2:1 to 5:1. Preferably the amide is obtained by reacting N-oleyl propylenediamine with oleic acid in a 1: 1 mole ratio. The products are used as lubricant additives (see Division C5).</p> |
