<p>PURPOSE:To reduce the amt. of air pollutant emitted from an internal combustion engine and improve the cetane number of a fuel oil by adding, to the oil, a compd. which is an org. peroxide and simultaneously a perbasic compd. of a metal salt of an org. acid. CONSTITUTION:A compd. which is an org. peroxide and simultaneously a perbasic compd. of a metal salt of an org. acid is prepd. A perbasic compd. is such a salt compd. that the amt. of the salt-constituting metal contained is higher than equivalent to that of the salt-constituting acid contained. Such a compd. is obtd. e.g. by putting an org. acid (an unsatd. carboxylic acid is esp. pref.), a diluent (e.g. n-hexane), a metal hydroxide (a Ca salt is esp. pref.), and if necessary a perbasic accelerator (e.g. an alcohol) into a reactor, raising the temp. of the reaction system, converting it into a carbonate to thereby convert the resulting perbasic compd. into a colloidal dispersion, and blowing oxygen into the dispersion. The molar ratio of the metal to the acid is 2-40. Thus obtd. peroxide is added to a fuel oil (e.g. light oil) in a metal concn. of 20-5,000ppm, reducing the emission of soot, etc., and improving the cetane number.</p> |
