Embodiment

[0043] The titanium mesh was cut into a size of 80.0mm×10.0mm×0.2mm, mechanically polished, acetone and ethanol sonochemically degreased for 30 minutes each. At room temperature, chemical polishing treatment (polishing liquid: HF: HNO 3 :H 2 O=1:4:5 volume ratio), and then rinsed with deionized water for use. Accurately weigh 1.576g of H 2 C 2 o 4 ·H 2O and 0.75g of ammonium fluoride are completely dissolved with a certain amount of distilled water, and the volume is adjusted to 100mL with distilled water to prepare 0.125M H 2 C 2 o 4 ·H 2 O, mass fraction is the ammonium fluoride solution of 0.75%. Ultrasonic stirring to fully dissolve. The cut electrode was immersed in the prepared solution as the anode, and the platinum mesh was used as the cathode, the temperature was kept at 25°C, the voltage was 30V, and the nanostructured TNTs anode was obtained after continuous anodic oxidation for 1.5 hours. Use adhesive tape to adhere and tear off the nano-TNTs structure o...

Abstract

The invention discloses chloro acetaldoxime cleaner production and a RuO2@TNTs anode used for cleaner production. A preparation method of the anode comprises the steps that a titanium mesh subjected to chemical degreasing and cleaning is arranged in a polishing agent for chemical polishing treatment; the titanium mesh is anodized through a two-electrode working system; a newly formed unstable surface layer formed after anodizing of the titanium mesh anode is removed through adhesive tape adsorption; the titanium mesh is used as the anode, the two-electrode working system is used continuously,the voltage is increased, and a nano-structure titanium dioxide array anode (TNTs) is obtained through oxidizing the TNTs anode is oxidized and annealed; ruthenium trichloride, distilled water and concentrated hydrochloric acid are mixed into a mixed solution with 5mM ruthenium trichloride and 0.5 wt% of hydrochloric acid; the annealed TNTs anode is put into the mixed solution; then the mixed solution where the TNTs anode is soaked in is subjected to hydro-thermal treatment; and the TNTs anode is oxidized again and then annealed, and the in-situ-grown nano-structure RuO2@TNTs anode is obtained.

Description

technical field [0001] The present invention relates to a method for in-situ growth of nanostructured RuO on titania nanoarrays (TNTs) by hydrothermal method 2 -TiO 2 anode, and its application to the electrochemical synthesis of chloroacetaldoxime. Background technique [0002] Carbamate pesticides are one of the most widely used chemical pesticides in the world because they have no special odor and are stable. Methomyl is a large-yield insecticide among carbamate pesticides. It has systemic properties and also has contact and stomach poisoning effects. (Kaplan A M.Toxical App pharmacol, 1977,40 (1): 1.) At present, what the manufacturer majority of my country produces methomyl adopts the acetaldehyde method production process, and wherein yield is only 45%~56%, This is because the intermediate products acetaldehyde oxime and chlorinated acetaldehyde oxime are extremely unstable and easy to decompose. [0003] Chloroacetaldoxime, as a key component in the synthesis of me...
