Embodiment 1

[0024] The synthetic method of embodiment 1 quinoline sulfonate (a-1) environmental protection acaricide:

[0025]

[0026] In an ice bath, using triethylamine as a catalyst, add p-chloro (or fluoro) benzenesulfonyl chloride dropwise to the dichloromethane solvent of 8-hydroxyquinoline or 5-chloro-8-hydroxyquinoline (1:1 molar ratio) After mixing and stirring uniformly for 1 h, the reaction was stirred at room temperature 25° C. for 24 h. After the reaction is completed, concentrate, crystallize, and wash repeatedly with deionized water to remove unreacted by-products of benzenesulfonyl chloride. The yield was 85%.

Abstract

The invention discloses a novel sulfonate antibacterial anti-mite agent and a research method for an efficient complexation of the agent. The novel sulfonate antibacterial anti-mite agent comprises quinolin-8-yl 4-chlorobenzenesulfonate and 2,3-dichlorophenyl 4-fluorobenzenesulfonate; and an efficient compound anti-mite agent preferably comprises quinolin-8-yl 4-chlorobenzenesulfonate and 2,3-dichlorophenyl 4-fluorobenzenesulfonate with a ratio of 3:2. The novel anti-mite agent is a sulfonate antibacterial anti-mite agent possessing the advantages of being wide in antibacterial spectrum, efficient, high in durability, safe and the like, and is applicable to substantially reduce levels of dermatophagoides pteronyssinus and dermatophagoides farina allergens of household interior ornaments, carpets, sofas and mattresses. The sulfonate antibacterial anti-mite agent is characterized by possessing both extremely strong mite contact killing capability and extremely strong smell mite killing capability.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to the research and development and preparation technology of a new type of odor-resistant antibacterial and anti-mite agent with high efficiency. Background technique [0002] Dozens—thousands—of mites are found in every gram of air in the indoor air we live in, with 20-40 species. The lifespan of the mite is about 3 months, and the female mite lays about 50 eggs in a lifetime, which increases geometrically, and develops from one female mite to 13 million eggs after 60 days. Among the indoor mites, dust mites are the most common. In the home, the most mites are distributed in carpets, followed by quilts, and then mattresses, pillows, floors, sofas, etc. Thousands of dust mites live in beds, pillows, bedding, decorative fabrics and carpets. They will produce a strong allergen, causing allergic diseases such as allergic asthma, allergic rhinitis and allergic dermatitis. C...
