    Abstract: Diperphthalic acids are prepared from hydrogen peroxide and the phthalic acid in an alkanesulfonic acid reaction medium by using finely subdivided phthalic acid with a particle dimension below 0.1 millimeter, more notably in the range of from 0.001 to 0.1 millimeter. A unique crystal form of diperisophthalic acid is obtained, for example, by reaction of isophthalic acid of less than 0.044 millimeter (less than 325 mesh).

    Abstract: WHERE R, R1 and X are as heretofore defined and second contacting said peroxynitrate with a reducing agent to form said substituted nitroalkyl nitrate, the first and second contacting being conducted in the presence of inert liquid. The nitroalkyl final products of the invention are useful as fuel additives to increase power output of petroleum distillates such as gasoline and kerosene. Further, they are useful as intermediates in the preparation of surfactants, fuel and lubricant additives, insecticides, fungicides (e.g. controlling early blight in bean plants), pharmaceuticals and polymers.

    WHERE R, R1 and X are as heretofore defined with a mixture of dinitrogen tetroxide and oxygen to form substituted nitroalkyl peroxynitrate of the formula:

    where R2 is alkyl of from 1 to 10 carbons of phenyl and R3 is hydrogen, phenyl or alkyl of from 1 to 10 carbons, and where Y is -OONO2 or -ONO2, said nitroalkyl nitrates being prepared by first contacting a substituted alkene of the formula:
