Embodiment 1

[0019] The novel composite iodine disinfectant is made from raw materials containing 60% dicationic quaternary ammonium salt, 3% iodine, 1% phosphoric acid and the balance of water by weight percentage.

[0020] The dicationic quaternary ammonium salt is 2-hydroxyl-N-alkyl-methylpropane-1,3 ammonium chloride, and its structural formula is as follows: R 1 The carbon chain length of the group is 1 carbon atom, R 2 The carbon chain length of the group is 12 carbon atoms. See the content recorded in Example 8 for its synthesis method.

[0021] The preparation method of the novel composite iodine disinfectant is as follows: weigh each raw material according to the above weight percentage; add the dicationic quaternary ammonium salt, phosphoric acid and water into the reaction kettle, heat to 40°C while stirring, keep warm, increase the stirring speed and continue stirring , add iodine, then insulated and stirred and reacted for 6 hours, dissolved completely to iodine, and coole...

Embodiment 2

[0023] The novel compound iodine disinfectant is made from raw materials containing 60% of dication quaternary ammonium salt, 5% of iodine, 5% of phosphoric acid and the balance of solvent according to the percentage by weight. Described solvent is water and ethylene glycol, and wherein ethylene glycol accounts for 3% in raw material, and water accounts for 12%.

[0024] The dicationic quaternary ammonium salt is 2-hydroxy-N-alkyl-methylpropane-1,3 ammonium chloride described in Example 1.

[0025] The preparation method of the novel composite iodine disinfectant is as follows: weigh each raw material according to the above weight percentage; add the dicationic quaternary ammonium salt, phosphoric acid, ethylene glycol and water into the reaction kettle, heat to 40°C while stirring, keep warm, and increase the stirring speed After that, continue to stir, add iodine, then insulated and stirred for 6 hours, dissolve completely to iodine, and cool down to obtain the novel composi...

Embodiment 3

[0027] The novel compound iodine disinfectant is made from raw materials containing 30% dication quaternary ammonium salt, 1.6% iodine, 1% phosphoric acid, 5% hydrochloric acid and the balance ethanol solvent by weight percentage.

[0028] The dicationic quaternary ammonium salt is 2-hydroxy-N-alkyl-methylpropane-1,3 ammonium chloride described in Example 1.

[0029] The preparation method of the novel composite iodine disinfectant is as follows: weigh each raw material according to the above weight percentage; add dicationic quaternary ammonium salt, phosphoric acid, hydrochloric acid and ethanol into the reaction kettle, heat to 60°C while stirring, keep warm, and increase the stirring speed Continue to stir, add iodine, insulate and stir reaction 2 hours afterwards, dissolve completely to iodine, cooling, obtains the novel composite iodine disinfectant of embodiment 3.

Abstract

The invention provides a novel composite iodine disinfectant as well as a preparation method and an application thereof. The novel composite iodine disinfectant is prepared from raw materials, including quaternary ammonium salt, iodine, potassium iodate, inorganic acid and water, in percentage by weight. The preparation method comprises steps as follows: firstly, the quaternary ammonium salt, the inorganic acid and the water are mixed, heated and heat-insulated, then the iodine and the potassium iodate are added, and a continuous heat-insulation mixing reaction is conducted until the iodine is completely dissolved. The composite iodine disinfectant has characteristics of the high sterilization speed and the high efficiency of iodine disinfectants as well as the characteristic of long sterilization and bacteriostatic duration of quaternary ammonium salt disinfectants, so that the usage frequency can be reduced. The preparation method is simple, the technological process is simple and easy to control, the production cycle is short, the production cost is low, and the method is suitable for industrial production. The composite iodine disinfectant can be used as a sterilization product applied to preparation of main components and is good in stability, non-toxic and non-irritating; the composite iodine disinfectant can also be applied to sterilization of animal husbandry and aquaculture and is good in sterilization and bacteriostatic effect.

Description

technical field [0001] The invention relates to the technical field of disinfectants, in particular to a novel compound iodine disinfectant used in animal husbandry disinfection and aquaculture disinfection and its preparation method and application. Background technique [0002] In order to achieve the purpose of disinfection of pollutants, iodine disinfection products of different types, different dosage forms, and different functions are being widely used in hygiene, daily life, agriculture, animal husbandry and breeding, and drinking water. Currently, the widely used disinfectants are mainly iodine , quaternary ammonium salts, and chlorine-containing disinfectants, but in actual use, a single disinfectant has obvious defects, such as: quaternary ammonium salt disinfectants have poor bactericidal effect, high concentration, iodine and Although chlorine disinfectant has good bactericidal effect, it has a short duration and high frequency of use. Therefore, there has been ...
