Dihydroxymethyl butyric acid (DHMBA) is a common chemical raw material, widely used in medicine, pesticides, plastics, coatings and other fields. Due to its certain hazards and toxicity, it is necessary to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment.

This article will detail the physical and chemical properties, toxicity hazards, and safety requirements for storage and transportation of dimethylolbutyric acid to help companies understand and comply with relevant regulations to ensure the safe use and operation of products.

1. the physical and chemical properties of dimethylol butyric acid

dimethylol butyric acid is a colorless or slightly yellow transparent liquid with a pungent odor. It is soluble in water, ethanol, ether and other organic solvents, but insoluble in petroleum ether. Dihydroxymethyl butyric acid is highly acidic and corrosive, and can react with metals to generate hydrogen. In addition, it is also flammable and oxidizing, in case of open flame, high heat or oxidant contact, there is a risk of combustion and explosion.

2. the toxicity of dimethylol butyric acid

dimethylol butyric acid has certain harm to human body. After contact, it may cause irritation symptoms of skin, eyes and respiratory system, such as redness, pain, cough, etc. Prolonged exposure or inhalation of high concentrations of dimethylolbutyric acid vapor may cause damage to the liver, kidneys and other organs. In addition, dimethylol butyric acid may also cause allergic reactions, such as skin rash, asthma and so on.

3. dimethylol butyric acid storage and transportation safety requirements

In order to ensure the safety of dimethylol butyric acid during storage and transportation, the following specifications need to be observed:

1. Storage requirements: dimethylol butyric acid should be stored In a cool, ventilated and dry warehouse, away from fire and heat sources. The temperature should not exceed 30 ℃, and the relative humidity should be kept below 75%. The storage area shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. The storage container should be well sealed, avoid direct sunlight and high temperature environment.
2. Transportation requirements: Dimethylolbutyric acid shall comply with the regulations on the transportation of dangerous goods during transportation, and shall be transported by special tankers or tankers, and ensure that the vehicles have good sealing and anti-static facilities. Vigorous vibration, friction and impact shall be avoided during transportation to prevent container breakage and leakage. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment, and hang dangerous goods transport signs.
3. Personnel protection: Personnel exposed to dimethylolbutyric acid should wear protective gloves, goggles, gas masks and other personal protective equipment to avoid skin, eyes and respiratory system contact with the substance. In case of leakage, the contaminated area shall be evacuated immediately and necessary decontamination shall be carried out.
4. Emergency treatment: in case of dimethylol butyric acid leakage accident, the emergency plan shall be started immediately, effective measures shall be taken to control the leakage source, prevent the leakage from spreading, and handle the leakage safely. At the same time, immediately report to the local environmental protection department and safety supervision department, and cooperate with relevant departments to investigate and deal with the accident.

In short, as a common raw material for the production of chemicals, dimethylolbutyric acid needs to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. Enterprises should strengthen the training and education of employees, improve their safety awareness and operation skills, and ensure the safe use and operation of products.
