| Broad spectrum acaricide | Amitraz is a broad spectrum formamidine class acaricidal pesticide. In 1971, its acaricidal activity was reported by Palmer (B.H.Palmer) et al. In 1973, Boots (Boots Co.Ltd.) recommended it as an acaricide. Chemical name: 1,5-bis-(2,4-dimethyl-phenyl)-3-methyl-1,3,5-triazole-1,4-pentadiene, the original drug is white or yellow needles-like crystal with some flavor of carbon amine. Density: 0.3, a melting point of 86~87°C, vapor pressure in 20°C of 506.6 × 10-7 Pa, slightly soluble in water, soluble in organic solvents such as xylene, acetone and methanol. It is stable to temperature and light under anhydrous condition; however, it is unstable under acidic condition. It is non-flammable, non-explosive, and easily to get decomposed and corrupted upon long-term storage in damp places. It has effects of contact-killing, apastia, repellent. Moreover, it has certain effects such as stomach poisoning, fumigation and the suction effect. It is effective against various instars of tetranychidae, but less effective against overwintering eggs. It has a variety of toxicity mechanisms with the main effect of inhibition of monoamine oxidase activity. It can stimulate non-cholinergic synapses of the central nervous system of pest mites. It can also effectively fight against pest mites which is resistant to other kinds of acaricide. Its efficacy can last for 40 to 50 days. It is mainly used for prevention and treatment of many kinds of pest mites among a variety of crops such as fruit, vegetables, tea, cotton, soybeans, and sugar beets. It also has good control effect against psyllid class and some kinds of lepidopteran pest’s egg. It also has partial control effects on scales, aphids and cotton bollworm, red bollworm, etc. It can be further used for controlling cattle mites, sheep mites and bee mites. Mixing amitraz with organophosphate and pyrethroid, avermectin can enhance the effect and expand insecticidal spectrum. Pesticide ready-mixture also contain 10.8% Avi ? A double cream. The product is of moderate toxicity to human, animal. Acute oral administration for rate: LD50 is 500~600 mg/kg; acute percutaneous administration of rabbit: LD50> 200 mg/kg; acute inhalation for rat: LC50 of 65mg/L.

| Production method | It comes from the reaction of 2,4-dimethyl aniline, triethyl orthoformate and methylamine. The consumption amount of raw materials is that: 2,4-dimethyl aniline (off 100%): 350kg/t, triethylorthoformate (off 100%): 500kg/t, monomethylamine 70kg/t, xylene 750kg/t. Method one： Preparing of N-2,4-dimethylphenyl-N'--methyl-formamidine. Xylene is nitrated, reduced and separated to obtained 2,4-dimethyl aniline. Then acidify with hydrochloric acid to yield the corresponding salts. Protocol: The mixture of 55.1g (0.35mol) 2,4-dimethylaniline hydrochloride, 83.7g (0.4mol) of p-toluenesulfonyl chloride and 150mL N-dimethylformamide was cooled and stirred. After the end of the exothermic reaction, stir the mixture at room temperature for 4h, add then pour them all into cold water for adjustment into basicity with 10mol/L sodium hydroxide solution. During this time, the temperature was kept below 10 °C. Filter, wash with water, dry, and re-crystal using cyclohexane to obtain N-2,4-dimethylphenyl-N'-methyl formamidine, m.p. 75~76 °C, yield 85%. The Synthesis of amitraz: The mixture of 19.4g (0.12mol) N-2,4-dimethylphenyl-N'-methyl formamidine, 0.3 g of p-toluenesulfonic acid, and 195mL of xylene is heated and refluxed for 48 h. dried was heated at reflux for 48h to release trimethylamine . After the completion of the reaction, distill out the xylene and solidify the residue under reduced pressure. Re-crystal twice using isopropanol to obtain amitraz, melting point 88~89 ℃, yield 90%. Or perform reaction in the presence of cyanophenyl with Cu2O as catalyst. Preparation Method Two Triethylorthoformate was reacted with 2,4-dimethyl aniline to get N-(2,4-xylene imino) ethyl (referred imidate). Then pass the dry methylamine gas into the imino ether, yielding Monocarboxamidine (N-2,4-xylyl-N'-methyl formamidine). Monocarboxamidine and imino ether is condensed into amitraz. Preparation Method Three 2,4-dimethylaniline is reacted with formic acid to obtain N-2,4-xylene, dimethylformamide. Then interact with phosgene with triethylamine as acid binding agent to get 2,4-dimethylphenyl isocyanide. Then push dry methylamine gas into the mixture of dimethylphenyl isocyanide and cuprous oxide, reaction. Add cyclohexane (when the reaction mixture is still hot) after the completion of reaction, cool and filter out the Monocarboxamidine. Then react it with dimethylphenyl isocyanide in the presence of benzene to obtain amitraz. |
