Acute Toxicity (LD50) Data and Hazard Classification of n-Butyl Acrylate?

n-Butyl Acrylate Acute Toxicity (LD50) Data and Hazard Classification

Butyl acrylate is an important chemical product, widely used in coatings, adhesives, plastics and other fields. It may cause harm to the human body and the environment in the process of production, storage and use, so it is very important to study its acute toxicity and to classify the risk level. This article will focus on the theme of "acute toxicity of n-butyl acrylate (LD50) data and risk classification" for a detailed analysis.

1. n-Butyl Acrylate Acute Toxicity (LD50) Data

Acute toxicity (Acute Toxicity) refers to the harmful effects of chemical substances on the human body or other organisms in a short period of time through oral administration, inhalation or skin contact. LD50(Lethal Dose, 50%) is an important indicator of acute toxicity, which refers to the dose that causes 50% of individual deaths in a certain number of subjects. The LD50 data of n-butyl acrylate is usually obtained through animal experiments, and the experimental results can provide a basis for the classification of risk levels.

According to relevant research, the LD50 data of n-butyl acrylate may be different under different experimental conditions. For example, the oral LD50 for mice is about 500-1000 mg/kg, while the LD50 data for rats may be around 500 mg/kg. These data show that the acute toxicity of n-butyl acrylate is relatively low, but necessary protective measures are still needed.

2. n-Butyl Acrylate Hazard Classification

Hazard classification is based on the toxicity data, physical and chemical properties and potential hazards of chemical substances. The hazard class of n-butyl acrylate is usually assessed according to the standards of the International Organization for Standardization (ISO) or the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

Based on LD50 data and related toxicity studies, the hazard level of n-butyl acrylate may be classified as "low toxicity" or "toxic. This classification helps companies take appropriate protective measures during production and use, such as wearing protective equipment, good ventilation, and avoiding skin contact.

3. OF ACUTE TOXICITY OF N-BUTYL ACRYLATE ON PRODUCTION AND STORAGE

The acute toxicity data of n-butyl acrylate and its hazard classification directly affect the safety of its production and storage. In the production process, enterprises should strictly follow the safety operation procedures and take effective ventilation, protection and emergency measures. When storing, should choose a cool, well-ventilated place, and away from the fire and oxidant.

The physical and chemical properties of n-butyl acrylate also need to be considered. For example, its flammability may increase the risk of fire and explosion. Therefore, in the process of storage and transportation, the fire source and high temperature environment must be strictly controlled to ensure safety.

4. n-Butyl Acrylate Hazard Classification Practical Significance

The classification of danger levels is not only a theoretical classification, but also has practical guiding significance. By understanding the hazard level of n-butyl acrylate, companies can develop appropriate safety plans to reduce potential risks. For example, conduct regular safety training, develop emergency response plans, and set up safety warning signs.

Hazard classification also helps regulators manage chemicals effectively. By referring to LD50 data and hazard classification, regulatory authorities can formulate more scientific regulations and standards to ensure the safety and sustainable development of the chemical industry.

5. summary

The acute toxicity (LD50) data of n-butyl acrylate and its hazard classification are important basis for evaluating its safety and formulating protective measures. Through experiments and research, we have learned that the toxicity of n-butyl acrylate is relatively low, but necessary safety measures still need to be taken. Enterprises should operate in strict accordance with relevant standards during production, storage and use to ensure the safety of employees and the environment.

Understanding the acute toxicity data and hazard classification of n-butyl acrylate will not only help improve the safety of chemical production, but also promote the development of the industry in a more environmentally friendly and sustainable direction.
