Abstract
Abstract THIS SPECIFICATION DISCLOSES CYCLO-SUBSTITUTED GAMMABUTYROLACTONES HAVING THE FORMULA: O<(-CO-C(-R1)(-R2)-CH(-)-R-CH(-)-) WHERE BOTH CH''S ARE JOINED IN THIS FORMULA, R MAY BE (CH2)N WHEREIN IS A WHOLE NUMBER AND IS AT LEAST 6 BUT NOT GREATER THAN 15, AN ALKYLENE GROUP CONTAINING AT LEAST 3 BUT NOT MORE THAN 10 CARBON ATOMS, OR A BUTYROLACTONE CONNECTED THROUGH ITS BETA AND GAMMA CARBON ATOMS WITH 1 TO 8-CH2-GROUPS INTERPOSED BETWEEN EITHER OR BOTH ITS BETA OR GAMMA CARBON ATOMS. R1 AND R2 MAY BE HYDROGEN, CHLORINE, OR A HYDROCARBYL, CARBOXYL, AMIDO, CYANO, ISOCYANO, OR NITRO GROUP OR MAY BE AN ALKYL GROUP SUBSTITUTED BY ANY OF THE LATTER FIVE GROUPS. R1 MAY BE THE SAME AS OR DIFFERENT FROM R2. THESE LACTONES HAVE VARIOUS USES SUCH AS ANTIWEAR ADDITIVES FOR HYDROCARBON FUELS, AS INHIBITORS OF OXYGEN CORROSIONOF IRON, AND AS A PRECURSOR FOR THE PREPARATION OF ANTIOXIDANTS FOR HYDROCARBON FUELS AND LUBRICANTS.
