This disclosure relates to cold cranking simulator viscosity (CCSV) boosting base stocks that allow flexibility for engine oil formulations to meet both high and low temperature viscosity requirements while maximizing fuel efficiency. The CCSV-boosting base stocks can include C28-C60 hydrocarbon materials, linear esters, tertiary amides, dialkyl carbonates, aromatic alcohols, and aromatic ethers. This disclosure also relates to lubricating oil formulations containing the CCSV-boosting base stocks, and a method for improving fuel efficiency in an engine by using as the engine oil a lubricating oil formulation containing one or more of the CCSV-boosting base stocks and/or cobase stocks.

A composition for a heat cycle system contains a working medium for heat cycle containing 1-chloro-2,3,3,3-tetrafluoropropene and a refrigerant oil.

The present disclosure provides, in part, a solvent compound for use as a slow evaporating replacement. More specifically, the present disclosure relates to volatile organic components (VOC)-exempt solvent compounds that may be used as a slow evaporating replacement that may, for example, be useful as a component or diluent in the production of paints and coatings, and other industrial products.

The present disclosure provides a dialkyl carbonate prepared from a methyl branched primary C.sub.16-C.sub.17 alcohol. The dialkyl carbonate is prepared by transesterifying a reactant dialkyl carbonate with the methyl branched primary C.sub.16-C.sub.17 alcohol under transesterification reaction conditions. The subsequently produced dialkyl carbonate may be used in various applications, including, but not limited to, in lubricating, cosmetic and textile products and applications.

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf, and CO2. The compositions are useful in processes to produce cooling and heating, in methods for replacing refrigerant R-32, and in refrigeration, air conditioning or heat pump systems. These inventive compositions are match cooling performance for R-32 with GWP less than 400 or less than 300.
