Abstract: A transformer oil basestock is disclosed that includes at least 99 wt % of naphthenes and paraffins, based on the total weight of the transformer oil basestock, wherein the weight ratio of naphthenes to paraffins is at least 1, as measured by GC-MS, and wherein the paraffins consist essentially of isoparaffins, as determined by GC-FID. In addition, a transformer oil composition is disclosed that includes the transformer oil basestock, an anti-gassing agent and an antioxidant.

Abstract: Viscoelastic fluid compositions are provided that have improved properties for suspending particulate active ingredients. Methods for forming the compositions are also provided. The compositions preferably have a non-Newtonian behavior, so that the viscosity of the composition at low shear rates is suitable for keeping solid particles in the form of a stable suspension while also providing a reduced viscosity at higher shear rates (such as a substantially reduced or minimized viscosity) to allow for pumping, tank mixing, and/or distribution of the composition, for instance by spraying.

Abstract: Noble metal or other preformer catalysts used to convert cobalt salts to hydrido cobalt carbonyl for use in the oxonation of olefins are reactivated or regenerated by treatment with a mixture of an aqueous organic acid solution and an alcohol at a temperature of about 120.degree. C. to 170.degree. C. and a pressure of about 13.78 MPa to 31.00 MPa for about 2 to 50 hours.

Abstract: Carbonaceous preformer catalysts used to convert cobalt salts to hydrido cobalt carbonyl for use in the oxonation of olefins are activated or regenerated by treatment with an aqueous cobalt salt solution in the presence of a light alcohol having from about 4 to 7 carbon atoms and syn gas prior to exposure to or processing with any other organic stream at a temperature of about 120.degree. C. to 190.degree. C. and a pressure of about 13 MPa to 32 MPa for about 2 to 50 hours.
