Abstract: A process for the preparation of citric acid which comprises contacting an unsaturated compound selected from 3-methylene-1,5-pentanediol and its esters with a nitric acid solution in an amount of 2 to 50 mols of nitric acid feed per mol of unsaturated compound feed, and at least 0.005 mol percent nitrogen dioxide based on nitric acid, at a temperature between -10.degree. and 120.degree. C., to thereby oxidize said unsaturated compound to citric acid. Preferably the contacting of the unsaturated compound so as to synthesize citric acid is carried out in the absence of any substantial amount of vanadium as the presence of vanadium catalysts has been found to effectively prevent the recovery of good yields of citric acid from the process.The citric acid synthesis preferably is carried out by an overall process wherein isobutene is reacted with two mols of formaldehyde to produce 3-methylene-1,5-pentanediol, which is then converted to citric acid by reaction with nitrogen dioxide/nitric acid.

Abstract: A process is set forth for the production of ketones by the action of water and a hydrated molybdenum(VI)-oxygen compound upon an alkene feed. The reaction occurs in the range from 200.degree. to 400.degree. C.

Abstract: Sulfur-based foams are produced by heating to liquid state a sulfur formulation containing a minor amount of a gas-producing component in a first (molten) zone; passing the mixture maintained in liquid form to a second (mixing) zone where it is mixed with a foaming agent which in combination with the gas-produced compound releases gas, and the gas-containing mixture is passed from the second zone for use as a cellular construction material. Apparatus for carrying out the process is provided.

Abstract: Fungal growth in animal feedstuffs is inhibited by the use of di-carboxylic acid esters and compositions thereof. In addition to inhibiting the growth of fungi, the di-carboxylic acid esters increase the nutritional value of the animal feedstuff treated, and promote greater weight gain and feed efficiency response in animals fed the treated feedstuff compositions.
