The structure of 1o was characterized by 1H NMR. 1H NMR (400 MHz, CDCl3, ppm): δ 1.89 (s, 3H, -CH3), 2.19 (s, 3H, -CH3), 2.65 (s, 3H, -CH3), 7.19-7.28(m, 2H, Ar-H), 7.30-7.44 (d, 2H, J = 7.8 Hz, Ar-H).

These are the mass spectrometer, which provides data relating to compound structure: the infrared detector, the output from which is a consequence of chemical functionality, and the atomic emission detector which given information concerning elemental composite.
Summary Gas Chromatography is one of the most important tools in chemistry because of its simplicity, sensitivity and effectiveness in separating components of mixtures.

Preparation and anti-flame capability of Expandable Graphite Xiu-Yan Pang1, a * Ming-kai Song2, b 1, 2College of Chemistry and Environmental Science, Hebei University, Baoding 071002 People’ Republic of China aEmail: pxy833@163.com, bEmail: smk666ccc@126.com, * corresponding author Keywords: expandable; graphite; dilatability; sodium pyrophosphate; flame retardant; LLDPE; mechanism Abstract: Feasible conditions to get flame retardant expandable graphite (EG) with low initiation expansion temperature and high dilatability were obtained through orthogonal test and single factor experiment.
When EG is heated, it will become the so-called expanded graphite with porous structure and high expanded volume.

As can be seen in Fig. 6, the sample retained good crystallinity in the cellulose I structure, even after milling for 2 hours [14].

Instruction Titanium alloys have been widely used in aerospace, automobile manufacturing, ships, weapons and chemistry applications for their high specific strength, corrosion resistance and good mechanical properties, while the alloys also suffer from low hardness and poor tribological behaviors [1].
In order to reduce the coefficient of friction and improve the tribological properties of this kind of wear-resistant hard coatings, WS2 which has the lamellar structure like MoS2 and graphite, and easy to be sheared, forming transfer lubricious films between the friction pair interface has been employed as solid lubricant in numerous studies [3,4] .
