摘要:
A medicinal white oil composition is prepared from an isomerized base oil. The isomerized base oil is filtered through a filter bed containing an acid activated clay having a surface area of at least 100 m2/g, for the base oil to be in compliant with at least one of European Pharmacopeia 3rd Edition, US Pharmacopeia 23rd edition (USP), FDA 21 CFR 172.878 and FDA 21 CFR 178.3620(a) for direct food contact, and FDA 21 CFR 178.3570 (USDA H-1). The medicinal white oil in one embodiment has a UV absorbance at 260 to 350 nm of less than 0.1.

A compressor lubricant composition providing energy savings and exhibiting excellent oxidation stability is provided, as well as a process for preparation of the lubricant composition. The composition comprises: (i) from 68 to 99.999 wt % of an isomerized base oil or blend of isomerized base oils; (ii) 0.001 through 20 wt % of a blend of ashless additives, the ashless additives having a viscosity range at 40° C. of from 50 mm2/s to 60 mm2/s, a density at 20° C. of from 0.95 through 1.05 g/cm3, a flash point of greater than 100° C. (COC), solubility in mineral oil of greater than 5 wt %, sulfur content of from 4.8 wt % through 6.0 wt %, and phosphorus content of from 2.9 through 3.6 wt %; (iii) less than 1.0 wt % of a dithiocarbamate, wherein the Conradson carbon residue is less than or equal to 3.00. The dithiocarbamate is added to the base oil blend as a top treatment.
