Provided is a raw material powder for powder metallurgy, capable of preventing stains, surface defects and decarburization of a sintered body, improving strength and density thereof. The raw material powder for powder metallurgy is for use in the production of a sintered body that is sintered at a temperature of not lower than 500° C., composed of a mixture of a metal powder and a lubricant, in which the lubricant is melamine cyanurate or terephthalic acid. Alternatively, the raw material powder for powder metallurgy is for use in the production of a sintered body that is sintered at a temperature of not lower than 500° C, composed of a mixture of a metal powder, a first lubricant and a second lubricant, in which the first lubricant is melamine cyanurate or terephthalic acid, while the second lubricant is preferably erucic acid amide or stearic acid amide.

Systems and methods are provided for the fractionation of lubricant feeds. A lubricant feed can be introduced into a vacuum distillation tower having a reduced pressure and a reduced or minimized water vapor partial pressure. The lubricant feed can be separated into a plurality of lubricant boiling range products. The can allow an overlap in boiling ranges of one or more products separated from the lubricant feed to be reduced or minimized.

Stable, solid triamine compositions are disclosed. The pressed, cast, extruded or other solid compositions are suitable for antimicrobial, sanitizing and disinfectant applications. Ready-to-use solutions are obtained by dissolving the solid triamine compositions with water and the methods of use thereof are particularly suitable for cleaning, disinfecting, sanitizing, rinsing and/or lubricating. Beneficially, the solid triamine compositions are at least partially neutralized, allowing activity of 90% and greater of the biocidal triamine, and provide at least substantially similar or superior performance and micro efficacy to liquid formulations.

A C.sub.31 renewable base oil is disclosed that is suitable as a base oil to provide low viscosity base oils, such as having both low Noack volatility and low CCS-30° C. viscosity and/or to provide low viscosity base oils at the same time having a combination of acceptable HTHS and KV100 to allow the industry's base oil blenders to formulate high quality engine oils, such as SAE grade 0W-20, 0W-16, 0W-12 or 0W-8.

A dielectric fluid is provided comprising an oil and one or more compounds selected from the group consisting of phosphite compounds. It has been discovered that addition of one or more compounds selected from the group consisting of phosphite compounds to dielectric fluids comprising oil impart a stabilizing effect that reduces, inhibits or prevents formation of stray gases in the dielectric fluid during ordinary use.
