A two-step process for producing a difunctional organic compound is provided which comprises:

Method for preparing a difunctional aliphatic organic compound

Diketo dinitriles are produced from the reaction of a diester and a nitrile in the presence of an alkali metal base. Polymers derived from the diketo dinitriles are useful as molding resins.

Process for the production of diketo dinitriles and polymers derived

A method for controlling the reactivity of an ozonized reaction mixture formed by ozonizing an unsaturated compound, wherein the reactivity of the ozonized reaction mixture is controlled by introducing a reactivity controlling amount of a saturated fatty acid into the reaction mixture before contact with the ozone.

Method for controlling the reactivity of an ozonization reaction product

A carboxylic acid is made by contacting an organic compound having at least one olefinic bond with ozone to form a mixture of ozonization products; contacting the mixture of ozonization products with oxygen to form a mixture of oxidation products; contacting the mixture of oxidation products with oxygen in the presence of an effective amount of a catalyst selected from the group consisting of a manganese-exchanged X-zeolite, a manganese-exchanged Y-zeolite, a manganese-exchanged A-zeolite, or a combination thereof to form said carboxylic acid.

Process for making carboxylic acids

A convenient stereoselective process for the preparation of .alpha.-alkylidene-substituted-.gamma.-butyrolactones and .delta.-valerolactones is provided. The process involves reacting an .alpha.-acyl lactone, an aldehyde, and an alkali metal hydroxide in an inert diluent at an elevated temperature while removing water.

Process for converting .alpha.-acyl-substituted lactones to

Catalyzed process for oxidation of ozonides of unsaturates to carboxylic

Alpha-(p-alkoxybenzylidene) carboxylic acids are used as color stabilizers, processing aids and whiteners for soap.

Alpha-(p-alkoxybenzylidene) carboxylic acids as color stabilizers,

Process for the preparation of .alpha.-alkyl lactones by the steps of first reacting an .alpha.-acyl lactone, an aldehyde, and an alkali metal hydroxide together to form an .alpha.-alkylidene lactone, and then hydrogenating the .alpha.-alkylidene lactone.

Process for the preparation of alpha-alkyl lactones

A convenient process for the preparation of .gamma.-alkyl-substituted-.gamma.-butyrolactones and .delta.-valerolactones is provided. The process involves forming the .alpha.-alkylidene lactone by reacting essentially equimolar amounts of an .alpha.-acyl lactone, an aldehyde, and an alkali metal hydroxide in an inert diluent at an elevated temperature while removing water and hydrogenating the .alpha.-alkylidene lactone to obtain the corresponding .alpha.-alkyl lactone.
