Abstract: A METHOD FOR PREPARING OMEGA-NITROESTERS BY THERMALLY CLEAVING AND REACTING A CYCLIC ALPHA-NITROKETONE WITH AN ALCOHOL IN A NON-AQUEOUS ENVIRONMENT AT A TEMPERATURE OF FROM ABOUT 50 TO ABOUT 200*C. THE ESTERS SO PREPARED ARE USEFUL AS LUBRICANT AND FUEL ADDITIVES AND AS INTERMEDIATES FOR THE PRODUCTION OF AMINO ACIDS.
