  • Process for the preparation of mixtures of oil-soluble iron and magnesium salts of saturated aliphatic monocarboxylic acids and their use
    Patent number: 5145488
    Abstract: To prepare a mixture of oil-soluble iron and magnesium salts of saturated aliphatic C.sub.6 to C.sub.8 monocarboxylic acids, magnesium oxide is reacted with a C.sub.6 to C.sub.8 monocarboxylic acid in a solution of an iron salt of a saturated C.sub.6 to C.sub.8 monocarboxylic acid. The mixture is used as a combustion auxiliary.

  • Process for preparing carboxylic acids by catalytic oxidation of aldehydes
    Patent number: 4285875
    Abstract: A process for preparing carboxylic acids by the oxidative conversion of the corresponding aldehydes comprises oxidizing the aldehydes in the presence of a catalyst comprising the anion [Fe(CN).sub.5 H.sub.2 O].sup.-3. The catalyst may be selected from [Fe(CN).sub.5 H.sub.2 O].sup.-3, compounds that form [Fe(CN).sub.5 H.sub.2 O].sup.-3 under the reaction conditions, and their salts. The catalyst is useful for the oxidation of aldehydes with oxygen or oxygen-containing gases. The present process permits the use of lower reaction times and temperatures, and reduces the formation of undesirable reaction by-products.
