The present invention relates to an enzymatic process for the modification of free fatty acids (FFAs) derived from renewable feedstocks of bio-based oils. Specifically, the invention describes the hydrolysis of any bio-based oil, such as high oleic sunflower oil (HOSO), to FFAs, containing high amounts of oleic acid (OA), which is further hydrated to 10-hydroxystearic acid (10-HSA).

It is an object of the present technology to provide a magnetic recording medium that has a small total thickness and achieves excellent travelling stability.

The present technology provides a tape-shaped magnetic recording medium including a magnetic layer, an underlayer, a base layer, and a back layer, in which a servo pattern is recorded in the magnetic layer, a statistical value σ.sub.SW indicating non-linearity of a servo band and being obtained from a reproduction waveform of a servo signal of the servo pattern is 24 nm or less, the base layer contains polyester as a main component, an average thickness t.sub.T of the magnetic recording medium is 5.6 μm or less, the magnetic recording medium contains a lubricant, pores are formed in the magnetic recording medium, and an average diameter of the pores of the magnetic recording medium that is measured in a state where the lubricant has been removed from the magnetic recording medium and the magnetic recording medium has been dried, is 6 nm or more and 11 nm or less.

A magnetic recording medium that can exhibit good traveling performance during use is provided. This magnetic recording medium is a tape-shaped magnetic recording medium, and includes a substrate including a polyester as a main component, a base layer disposed on the substrate, and a magnetic layer disposed on the base layer. The kurtosis of the surface of the magnetic layer is 3.0 or more. The base layer and the magnetic layer each include a lubricant including a fatty acid and a fatty acid ester. In the lubricant, a ratio of the content of the fatty acid to the content of the fatty acid ester is less than 0.6.

A method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.
