Combined with synchronized monitoring techniques, purification processes for active constituent of alkylbenzene sulfonate have been optimized, and the total alkylbenzene sulfonate, mono-alkylbenzene sulfonate and di-alkylbenzene sulfonate can be obtained with purity over 90%. With the above active constituents as standard substances respectively, the determination of alkylbenzene sulfonate content in the original samples was carried out by high performance liquid chromatograph. The results showed the sample contained mono- and di-alkylbenzene sulfonate simultaneously, and the content of mono-alkylbenzene sulfonate was much higher than that of di-alkylbenzene sulfonate. They had maximum absorption at the wavelength of 224 nm, and the absorption coefficients of total alkylbenzene sulfonate and mono-alkylbenzene sulfonate were similar, higher than that of di-alkylbenzene sulfonate. With total, mono- and di-alkylbenzene sulfonate as standard substances respectively, the limits of quantitation were 5 mg/L, 5 mg/L and 10 mg/L, respectively. The determination result of active constituent was about 3% lower with total alkylbenzene sulfonate as standard substance than that with mono- and di-alkylbenzene sulfonate as standard substances simultaneously, owing to the weaker absorption coefficient of di-alkylbenzene sulfonate.

The synergism flame retardant effect of expandable graphite(EG) and intumescent flame retardant(IFR) on road asphalt was investigated by limiting oxygen index(LOI) and the flame retardant mechanism was analyzed by scanning electron microscopy(SEM).The results revealed synergism of EG and IFR has a good flame retardant effect which greatly improved LOIs and enhanced thermal stability by forming inflation homogenous porous carbon layer after combustion.

The CuHY zeolites adsorbents with different Cu loadings were prepared via impregnation method. The crystal structure of the adsorbent was characterized by XRD, and the surface acidity was measured by PyFTIR technique. The adsorption desulfurization performance was evaluated using fixed bed method with a WK2D micro coulometer analyzer. The results show that the adsorbents have the best adsorption desulfurization ability when the copper loading is 4%. The adsorption desulfurization performance becomes better with the decrease of the ratio of B acid amount and L acid amount. However, the adsorption desulfurization ability reduces severely, when copper loading is too large which results the surface copper oxide species, even though there is no B acidic sites existing on the surface of the adsorbent.
