Problems solved by technology

However, polyvinylpyrrolidone is a polymer surfactant with an average molecular weight of 10,000-70,000. It is difficult to biodegrade. If it is used for a long time, its residual accumulation will cause environmental pollution and damage to internal organs. In particular, complex iodine preparations Only the free iodine molecules slowly released from polyvinylpyrrolidone micelles play a role in disinfection and sterilization, and polyvinylpyrrolidone is only a carrier of iodine molecules, the purpose is to stabilize the iodine preparation, and itself has no bactericidal effect
Therefore, the addition of polyvinylpyrrolidone carrier will inevitably increase the use cost and price of iodine preparations significantly.

Embodiment 1

[0030] Example 1: Add 440g of monolauryl dimethyl tertiary amine and 800g of water into a 2000mL three-neck flask, add 10g of sodium carbonate catalyst at the same time, mix and stir, heat up to 60-70°C, and slowly add 202g of it dropwise at this temperature After the dibromopropane is added dropwise, continue to heat up to 70-80° C., and keep the temperature for 5-6 hours. After the reaction solution is transparent, after detecting that the free amine is less than 1.0%, add 10 g of iodine, and stir for 1.5 hours to obtain the product.

Embodiment 2

[0031] Example 2: In a 2000mL reactor, after adding 524g of monomyristyl diethyl tertiary amine and 800g of water, 11g of sodium carbonate catalyst sodium was added at the same time, and the mixture was heated to 65-75°C under stirring conditions, Then slowly add 188g of dibromoethane dropwise. After the dropwise addition, the temperature is raised to 70-75°C, and the reaction is heated for 6-7 hours. After the solution is transparent, 9.5g of iodine is added, and the product is obtained after 2 hours of reaction.

Embodiment 3

[0032] Example 3: After adding 440g of monodecyldiethyl tertiary amine and 600g of water in a 2000mL reactor, add 10g of sodium carbonate catalyst at the same time and heat the mixture to 60-70°C under stirring, then slowly drop 202g After the dibromopropane has been added dropwise, continue to heat up to 70-80°C and heat the reaction for 6-7 hours. After the reaction solution is clear and transparent, add 14g of iodine and stir for 1 hour to obtain the product.

Abstract

The disinfectant is one kind of complex containing quaternary ammonium salt cationic surfactant and iodine. It is produced through mixing the quaternary ammonium salt compound and iodine and reacting for 1-2 hr. It is used mainly for disinfection in animal raising and aquiculture, and has high sterilizing and algae-killing efficiency and high safety.

Description

technical field [0001] The bactericide of the invention belongs to the field of disinfectants, in particular to a bactericide containing a quaternary ammonium salt cationic surfactant complexed with iodine. Background technique [0002] Modern chemical disinfectants have developed very rapidly since their inception and have been widely used. Commonly used disinfectants include: aldehyde type glutaraldehyde, etc., peroxide type hydrogen peroxide, etc., iodine type iodine tincture, complex iodine, etc., chlorine compound type hypochlorous acid, chlorine dioxide, etc., biguanide type Chlorhexidine, etc., and surfactant-type bromogeramine, etc. Their bactericidal effects are all very good, but these bactericides also show common disadvantages such as irritation to the human body, poor stability and strong corrosion. [0003] Among the existing various complexed iodine preparations, the complexes of polyvinylpyrrolidone (PVP) and iodine have been most widely used. However, pol...
