Embodiment 1

[0031] The preparation of embodiment 1 sweet-scented cinnamon essential oil

[0032] (1) Collect fresh Osmanthus osmanthus petals, and carry out low-temperature baking and drying at 20° C. under anaerobic conditions until the water content of the petals is 40%, then take 1 kg of petals and place them in a high-speed pulverizer for pulverization, and the pulverized Osmanthus osmanthus Fragrant petals are placed in a supercritical carbon dioxide extraction device, adding 50% of the total weight of the petals with a volume fraction of 85% ethanol, regulating the flow rate of carbon dioxide to 15L / h, the extraction pressure to 20MPa, the extraction temperature to 60°C, and the extraction time to 2h. Separation under reduced pressure to obtain Osmanthus osmanthus extract;

[0033](2) Molecular distillation is carried out to the prepared Osmanthus osmanthus extract, at a feed temperature of 50°C, a distillation temperature of 105°C, a vacuum of 35MPa, an osmanthus extract flow rate ...

Embodiment 2

[0035] The preparation of embodiment 2 sweet-scented cinnamon essential oil

[0036] (1) Collect fresh Osmanthus osmanthus petals, and carry out low-temperature baking and drying at 25° C. under anaerobic conditions until the water content of the petals is 30%, then take 1 kg of petals and place them in a high-speed pulverizer for pulverization, and the pulverized Osmanthus osmanthus The fragrant petals are placed in a supercritical carbon dioxide extraction device, and 60% of the total weight of the petals is added with a volume fraction of 70% ethanol, the carbon dioxide flow rate is adjusted to 20L / h, the extraction pressure is 15MPa, the extraction temperature is 40°C, and the extraction time is 3h. Separation under reduced pressure to obtain Osmanthus osmanthus extract;

[0037] (2) Molecular distillation is carried out to the prepared Osmanthus osmanthus extract, at a feed temperature of 70°C, a distillation temperature of 95°C, a vacuum of 55MPa, a flow rate of osmanthu...

Embodiment 3

[0039] The preparation of embodiment 3 liquid mosquito-repellent incense

[0040] Example 3 The liquid mosquito-repellent incense comprises the following components by weight: 0.2 part of chloroflufenethrin, 0.5 part of cinnamon essential oil, 0.2 part of nobiletin, 0.5 part of alaretin, 0.2 part of octyl methoxycinnamate, 2,6 - 0.3 parts of di-tert-butyl-4-methylphenol, 0.24 parts of tea saponin, 0.06 parts of alkyl glycosides, 27.5 parts of carbitol, 27.5 parts of propylene glycol methyl ether acetate and 30 parts of water.

[0041] Preparation:

[0042] Mix chlorofluthrin, nobiletin, anobiletin, carbitol, propylene glycol methyl ether acetate and water, stir at 80rpm for 30min, then add tea saponin, alkyl glycoside and osmanthus essential oil, stir at 80rpm for 30min , and finally add octyl methoxycinnamate and 2,6-di-tert-butyl-4-methylphenol, and stir at 80 rpm for 15 minutes to obtain liquid mosquito coils.

Abstract

The invention discloses a liquid mosquito-repellent incense and a preparation method thereof. The liquid mosquito-repellent incense comprises, by weight, 0.1-0.5 part of a pyrethroid compound, 0.1-0.5part of Cheiranthus cheiri essential oil, 0.1-0.3 part of nobiletin, 0.2-0.6 part of fraxetin, 0.05-0.5 part of octylmethoxycinnamate, 0.05-0.5 part of an antioxidant, 0.1-0.4 part of a surfactant, 50-60 parts of a volatilization regulator and 30-40 parts of water. The liquid mosquito-repellent incense has a strong pharmacological effect, has remarkable mosquito repelling and killing effects, hasa lasting period of 720 h, has a low daily volatility amount, has a drug effect reaching A standards, also has the advantages of stable properties, non-decomposition in ultraviolet lights, small pesticide resistance of mosquitoes, low toxicity, safety, high efficiency, long-acting effect and environmental protection, and is an ideal choice for healthy home life.

Description

technical field [0001] The invention belongs to the technical field of hygienic insecticide products, and in particular relates to a liquid mosquito-repellent incense and a preparation method thereof. Background technique [0002] The electric heating liquid mosquito coil is the third generation mosquito coil, which was first developed by Japan and put on the market. Continuous use for 240-720 hours, just simply turn on and off the switch, and more convenient automatic control can be realized after configuring the timing element; the drug effect is more stable at each time period throughout the night during use, and there is no phenomenon of being bitten in the middle of the night; avoid using The fire source is safer to use; the liquid medicine can be volatilized into the space without waste, preventing the original medicine from being burned or remaining in the paper, and the utilization rate of active ingredients is high; it can avoid direct contact with the medicine with...
