Paragraph 0018-0021, (2019/04/13)
The invention relates to a pesticide synthesis technology field, discloses a 2, 2 - dimethyl butyric acid, use chloro- uncle pentane preparing Grignard reagent, then with the ester compound produced by the reaction of 2, 2 - dimethyl ester, followed by hydrolysis to obtain 2, 2 - dimethyl butyric acid. To avoid the traditional production of large amount of sulfuric acid used in the method of defect, reducing the risk of the working personnel, and the use of some conventional chemical reagent can prepare 2, 2 - dimethyl butyric acid, convenient to make the 2, 2 - dimethyl butyric acid.

The interaction between tert-butyl chloride and activated aluminum was studied by attenuated total reflectance Fourier transform infrared spectroscopy near room temperature (18-25°C). A long induc- tion period of ?240-260 min was observed. The AlCl4- ionic aluminum chloride complexes [AlnCl3n+1]-(n = 1, 2) and the molecular species AlCl3 were identified at the activated aluminum/tert-butyl chloride interface during the reaction. The formation of the ion in the liquid medium and the presence of the same ion and a molecular AlCl3 -tert-butyl chloride complex in the resinous products of the reaction were confirmed by 27Al NMR spectroscopy. The reaction products were analyzed qualitatively by GC/MS. The reactivities of activated aluminum and anhydrous aluminum chloride toward tert-butyl chloride under the same conditions were compared. A distinctive feature of the interaction activated aluminum and tert-butyl chloride is the dominant formation of the AlCl4 -ion. By contrast, the interaction between aluminum chloride and tert-butyl chloride yields the polynuclear ion and,Al2Cl7 - likely,Al3Cl10-. Pleiades Publishing, Ltd., 2010.
