What is the main use of 1,3-diiodo-5,5-dimethylhydantoin?
1% 2C3-dibromo-5% 2C5-dimethylhydantoyl urea, often referred to as the English abbreviation DBDMH. This product has a wide range of uses and is used in many fields.
First, in the field of water treatment, it is a powerful bactericidal disinfectant. It can be used for disinfection of drinking water, swimming pool water, industrial circulating water and other water bodies. There are many microorganisms in the water, which can easily deteriorate the water quality and threaten human health and the operation of industrial equipment. When DBDMH is put into water, it can quickly release effective bromine, which combines with the amino groups in the microbial protein to denature the protein, thereby efficiently killing bacteria, viruses, fungi and other microorganisms, ensuring clean water quality, preventing the spread of diseases, and maintaining the stable operation of the industrial circulating water system.
Second, in terms of medical and health care, it can be used for disinfection of the environment and medical apparatus. Hospitals, clinics and other places are prone to breed a large number of bacteria. DBDMH has good disinfection performance to disinfect environmental surfaces, medical apparatus, etc., effectively preventing the spread of bacteria and protecting the health of healthcare workers and patients.
Third, in the agricultural field, DBDMH can be used as seed disinfectant and soil disinfectant. Seed-carrying bacteria can cause poor crop growth and reduce production. Treating seeds with DBDMH can kill surface bacteria, improve seed germination rate and seedling survival rate. Soil disinfection can eliminate harmful microorganisms and pathogens in the soil, create a good soil environment for crop growth, and reduce the occurrence of soil-borne diseases. Fourth, in the industrial field, in addition to being used in circulating water systems, it can also be used as a fungicide for pulp in the paper industry to inhibit the growth of microorganisms in the pulp, prevent paper mildew, and improve paper quality. It is also used for anti-mildew treatment of leather in the leather industry to prolong the service life of leather products.

Under appropriate conditions, bromine atoms can be replaced by other functional groups, thus realizing the modification and transformation of compound structures, providing the possibility for the preparation of various organic compounds.
What are the precautions for the use of 1,3-diiodo-5,5-dimethylhydantoin?
1% 2C3-dibromo-5% 2C5-dimethylhydantoin should pay attention to the following points during use:
First, it is related to toxicity and protection. This substance is toxic to a certain extent. When operating, be sure to wear suitable protective equipment, such as gloves, goggles and masks, to prevent direct contact with the skin and eyes, and avoid inhaling its dust or mist. If you come into contact accidentally, you should immediately rinse with plenty of water and seek medical treatment according to the specific situation.
Second, about storage conditions. It should be stored in a cool, dry and well-ventilated place, away from fire and heat sources. It should be stored separately from oxidants, acids, etc., and should not be mixed to prevent dangerous reactions. The storage area should be equipped with suitable containment materials to deal with possible leakage.
Third, it involves the use of specifications. When configuring the solution, the dosage should be accurately calculated according to the required concentration, and attention should be paid to the operation sequence and conditions during the dissolution process to ensure that it dissolves fully and uniformly. When using, strictly follow the established operating procedures and dosage standards, and cannot be changed at will. At the same time, pay attention to its compatibility with other substances to prevent chemical reactions caused by improper mixing, resulting in reduced efficiency or even harmful products.
Fourth, for environmental impact. After use, properly dispose of the remaining substances and waste to avoid pollution to the environment. After this substance enters the environment, it may have an impact on ecosystems such as water bodies and soils, so its release to the environment should be minimized during use.
What is the production method of 1,3-diiodine-5,5-dimethylhydantoin?
The preparation method of 1% 2C3-dichloro-5% 2C5-dimethylhydantoin is as follows:
Take an appropriate amount of acetone, place it in a clean kettle, and slowly drop it into liquid chlorine under a low temperature environment. During this period, the temperature should be carefully controlled, and the temperature should not fluctuate greatly, so that the acetone and chlorine can fully react to generate 1% 2C3-dichloroacetone. This process requires close attention to the reaction phenomenon. After the reaction proceeds smoothly and reaches the expected degree of reaction, the chlorine can be stopped.
Take another amount of sodium cyanate and dissolve it in an appropriate amount of water to make a sodium cyanate solution. The prepared 1% 2C3-dichloroacetone is slowly poured into the sodium cyanate solution, and stirred at the same time to fully mix the two. During the reaction, the temperature, pH and other conditions of the reaction should be precisely controlled to ensure the smooth progress of the reaction.
After the above reaction is completed, an appropriate amount of sodium hydroxide solution is added to the reaction system to adjust the pH of the system and promote further transformation of the product. This step requires extra care. Due to subtle changes in pH, the purity and yield of the product may be affected.
Subsequently, the reaction mixture is filtered to separate solid impurities. The filtrate is concentrated to gradually evaporate the water in the solution, and the product concentration is increased. After concentration to a certain extent, cool and crystallize to obtain 1% 2C3-dichloro-5% 2C5-dimethylhydantoin crude product.
To improve the purity of the product, recrystallize the crude product. Select a suitable solvent, dissolve the crude product, heat to an appropriate temperature, so that the solute is fully dissolved in the solvent. Then, slowly cool the solution to allow the product to precipitate in a crystalline state. Filter again, collect crystals, and rinse with a small amount of clean solvent to remove impurities attached to the crystal surface. Finally, dry at a suitable temperature to obtain a pure 1% 2C3-dichloro-5% 2C5-dimethylhydantoin product.
The above preparation method requires the experimenter to have skilled operation skills and a rigorous experimental attitude, and all steps must be strictly followed in order to obtain the ideal product.
