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
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.
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.
1], associated to the C - H stretching band in olefinic carbons, showed that all catalysts were effective for hydrogenation reactions, therefore forming paraffinic hydrocarbons
Optimal low-temperature properties of PAMA can be achieved by an adequate ratio of long-chain alkyl groups relative to the present paraffinic hydrocarbons
in base oil (6), (30).
Paraffinic hydrocarbons are organic compounds commonly found in crude oil, consisting of various forms and combinations of aliphatic hydrocarbons, aromatic hydrocarbons, napthenes, and asphaltenes.
Etoumi (2007) observed a reduction in wax appearance temperature and heavy hydrocarbon fractions by biodegradation of paraffinic hydrocarbons using Pseudomonas and Actinomyces species.
Thirteen were found to contain air tainted with a group of paraffinic hydrocarbons
emitted by wet-process copiers.
The algal fatty acid product is catalytically decarboxylated and converted into paraffinic hydrocarbons
(alkanes), followed by mild hydrocracking and hydroisomerization to make biojet fuel comprised of C10-C15 branched paraffins.
