Abstract: A method of making wax articles and lubricity to textile yarns in which paraffin wax having a particular melting temperature is heated to a temperature above the melting temperature and thereby melted. A mold is then filled with a molten wax while being chilled to a temperature. Thereafter, the mould and the wax in the mould are heated to a temperature substantially the same as the melting temperature and the wax is subsequently removed from the mould. The sequenced chilling and heating impart to the moulded wax a particular molecular structure which enhances lubricity.

Abstract: High melting, deoiled and mildly deasphalted tank bottoms wax is catalytically refined in two stages using a catalyst comprising nickel molybdate on alumina. The first stage is maintained at a temperature at least about 50.degree. F. higher than the second stage and the temperature in the second stage is allowed to go no higher than about 575.degree. F. Hydrofined wax product from the second stage is recycled back into same and the temperature in the first stage is periodically increased in order to counteract deactivation of the catalyst. By using a judicious combination of process conditions, unrefined high melting tank bottoms microwax stocks can be made into high quality, high melting point microwax having excellent color and meeting FDA purity requirements.

Abstract: Methylenebis(dicyclopentyl phenols) in which at least one cyclopentyl group is ortho to the phenolic hydroxy group are effective antioxidants in a broad range of organic materials including mineral and synthetic lubricating oil and polyolefins.
