If the groups, R and R' are identical, the ketone is called a simple ketone, if unlike, a mixed ketone. They may be prepared by the oxidation of secondary alcohols; by the addition of the elements of water to hydrocarbons of the acetylene type RC CH ; by oxidation of primary alcohols of the type RR'•CH•CH2OH:RR'•CH•CH2OH -~ R•CO•R'+H2O+H2CO2; by distillation of the calcium salts of the fatty acids, CnH23102; by heating the sodium salts of these acids C.H2n02 with the corresponding acid anhydride to 19o° C. (W. H. Perkin, Jour. Chem. Soc., 1886, 49, p. 322); by the action of anhydrous ferric Chloride on acid chlorides (J. Hamonet, Bull. de la soc. chim., 1888, 50, p. 357), 2C2HSO001 C2H6• CO .
