Abstract: In a process for preparing overbased oil soluble naphthenates of molybdenum, copper, manganese and iron, wherein a metal sulfate is one of the reagents and an alkali metal sulfate is one of the products, cake formation which blocks reactor discharge lines is eliminated by maintaining the alkali metal sulfate as an aqueous solution and removing this solution from the reactor.

Abstract: Described are encapsulated slow release fertilizers prepared by providing a fertilizer substrate, spraying molten sulfur thereon; encapsulating the sulfur-coated fertilizer by solvent deposition of bitumen and then powder coating the bitumen- and sulfur-coated fertilizer with a finely ground, dry, mineral powder which reduces the tackiness of the combined coating.

Abstract: Saturated aliphatic hydrocarbons are converted to color-stable aliphatic sulfonic acids in a single step without any initiator but in the presence of a low molecular weight acyl oxide and under anhydrous conditions by the rapid removal of the products as they are being formed, followed immediately by cooling and degassing to remove sulphur dioxide, then by immediate neutralization and complete hydrolysis at the boiling point of the unstable acid precursors present in the neutralized sulphonates by boiling at constant volume at a pH of about 8-10. The alkali metal salts of the sulfonic acids prepared by this process are color and pH-stable and useful as biodegradable detergents.
