Abstract
Abstract BORATE ESTERS OF THE FORMULA: R5-(O-B(-O-(CH(-R2)-CH2-O)N-(CH(-R1)-CH2-O)M-R3)-O- (CH(-R2)-CH2-O)N-(CH(-R1)-CH2-O)M-R4)S WHEREIN R1 AND R2 ARE HYDROGEN OR METHYL, R3 AND R4 ARE EACH AN INDEPENDENTLY SELECTED ALKYL GROUP HAVING FROM 1 TO 20 CARBON ATOMS, R5 IS THE ORGANIC RESIDUE EXCLUSIVE OF REACTIVE HYDROXYL GROUPS OF A POLYOL OF THE FORMULA: (H(OCH2CHR7)Z)XN(R3)3-3 WHEREIN S IS AN INTEGER OF FROM 2 TO 3 INCLUSIVE, Z IS AN INTEGER OF FROM 1 TO 10 INCLUSIVE, R7 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND METHYL AND R3 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL OF FROM 1 TO 4 CARBON ATOMS, AND N AND M ARE POSITIVE INTEGERS INDEPENDENTLY SELECTED IN EACH CHAIN AND WHOSE SUM IS EACH CHAIN IS FROM 2 TO 20 ARE PREPARED BY SUCCESSIVELY REACTING BORIC ACID WITH A GLYCOL MONOETHER AND A POLYOL. THESE ESTERS ARE USEFUL AS STATBIZERS AND CORROSION INHIBITORS FOR LUBRICANTS AND NON-AQUEOUS HYDRAULIC FLUIDS.
