Formulating is done with aliphatic amine, anhydride, polyamide, Lewis-acid, and cycloaliphatic chemistries.
Aliphatic amines for fast cure at room temperature.
22], Williams and Taylor , Williams and Besler , and Williams and Nazzal , or via conversion of hydrogen-poor materials to coke, and cracking of aliphatic moieties to gas resulting in the selective concentration of aromatic compounds as reported by Burnham .
It is not possible (according to the available knowledge) to eliminate the formation of PAH in the obtained oil without elimination or decreasing the aromatization processes via secondary reactions through either a Diels-Alder type reaction or selective cracking of aliphatic compounds resulting in selective concentration of aromatic compounds.
Chemical class fractionation of the obtained shale oil using solid phase extraction on silica gel was particularly useful for separation of the oil into aliphatic, aromatic, ester and polar hydrocarbons.
The content of aliphatic material represented by the fractions pentane-1 and pentane-2 is lower in the oil obtained at pyrolysis under the nitrogen/steam atmosphere.
Covariates retained for regression models containing breath analyte exposure variables dichotomized about the median for aliphatic ([C.
Figure 1 illustrates mean endocrine levels across the menstrual cycle for participants' high and low aliphatic HC ([C.
We found that preovulatory LH in urine was lower in healthy, reproductive-age women who had higher internal doses of aliphatic HCs in exhaled breath.
