With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

通过样品外观的观察初步定性是否掺有杂质;利用纯蜂蜡在苯中溶解,而掺入的石膏、面粉和淀粉等杂质在苯中不溶而定量鉴定这类杂质;由酸值变化和乙醇溶解物的量,测定掺入的硬脂酸等酸性物质或其它的非酸性物质;由皂化值变化,定量测定掺入的动物脂等酯类物质或其它的非酯类物质;根据蜂蜡中的烃类在浓硫酸中可被炭化,加入的石蜡等矿物蜡不被炭化来测定此类掺杂物。

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.

Accordingly a further feature of the invention is a combined process wherein a dialkyl phenylethylmalonate is made from an alkyl phenylacetate and a dialkyl carbonate by a process comprising adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C, at least a chemically equivalent proportion of a lower aliphatic alcohol, subsequently adding an approximately equivalent proportion of a dialkyl carbonate and of an alkyl phenylacetate, heating the mixture to induce reaction and continuously distilling out the alcohol formed from the reaction zone and finally causing the sodio diethyl phenylmalonate so obtained to interact with an ethylating agent, such as ethyl halide, diethyl sulphate of ethyl p-toluene-sulphonate.

因此,本发明的另一个应用是一个组合工艺过程:二烷基苯基乙基丙二酸酯由烷基乙酸苯酯和二烷基碳酸酯得到,具体工艺过程是:向覆盖有沸点超过一百摄氏度的团庆化合物溶剂的金属钠中添加至少化学平衡的低级脂肪族醇,然后加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯,加热混合物引导反应进行,持续蒸馏把形成的醇类从反应区域移出,最后使获得的二乙基苯基丙二酸酯和乙基化试剂如卤代乙烷,二乙基硫酸酯形成乙基p-甲苯磺酸酯。

As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.
