Although the evaporation by heat was slightly higher at both 120[degrees]C and 150[degrees]C, all other properties were well within specification, including flash point, aniline point and paraffinic hydrocarbon content.
"On clean high-vacuum applications, paraffinic hydrocarbon oils are used without additives; all unsaturated aromatic constituents are removed from the oils--by refining and distillation--in order to maintain very low vapor pressures even at high pump operating temperatures.
Paraffinic hydrocarbons: Saturated hydrocarbon compounds with the general formula [C.sub.n][H.sub.2n+2] containing only single bonds.
C2-30 fatty acid esters, paraffinic hydrocarbons and mixtures thereof; at least one synthetic wax having a melting point of from about 30[degree]C to about 100[degree]C; and at least one film-former selected from the group consisting of trimethylsiloxy silicate, dimethicone silylate and mixture thereof; a silicone gel composition comprising an organosiloxane elastomer solvated or dispersed in a nonpolar oil; and an alcohol-based composition.
Hydroperoxides of paraffinic hydrocarbons actively decompose at temperatures of 180200[degrees]C.
This value is determined by the relation of carbon and hydrogen content in the molecule (H/C) and has maximum value for paraffinic hydrocarbons and minimum value for aromatic ones.
In this way, the polymer molecules govern the process of crystallization of the paraffinic hydrocarbons. This ensures adequate flow and lubricating properties of mineral oil also at low temperatures.
Paraffinic hydrocarbons are organic compounds commonly found in crude oil, consisting of various forms and combinations of aliphatic hydrocarbons, aromatic hydrocarbons, napthenes, and asphaltenes.
The fraction of paraffinic hydrocarbons, such as methane, ethane, etc., is 35-37vol.%.
Thirteen were found to contain air tainted with a group of paraffinic hydrocarbons emitted by wet-process copiers.
See Paraffinic hydrocarbons. Normal Butane ([C.sub.4][H.sub.10]): A straight-chain saturated (paraffinic) hydrocarbon extracted from both natural gas and refinery gas streams, which is gaseous at standard temperature and pressure.
