[Chemical Knowledge]：Specification for storage and transport of butyl acrylate

The safety storage and transportation specification
of butyl acrylate
1. Introduction

Butyl acrylate is an important chemical production raw material, widely used in coatings, adhesives, plastics and other fields. However, due to its flammable, explosive, toxic and other characteristics, it is necessary to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safe storage and transportation specifications for butyl acrylate.

2. the physical and chemical properties of butyl acrylate

butyl acrylate is a colorless transparent liquid with pungent odor. Relative density 0.8991. Melting point -70 ℃, boiling point 145.7 ℃,76 ℃(1.33kPa),65~66 ℃(0.4kPa), ignition point 421.11 ℃, flash point 54 ℃. Refractive index 1. 4004, viscosity 0.74mPa · s(25 ℃). Vapor pressure 13.33kPa(37.8°C). With ethanol, ether miscible, soluble in chloroform, acetone, insoluble in water. Flammable, in case of high heat, open flame or contact with oxidant, there is a risk of combustion. Butyl acrylate vapor and air can form an explosive mixture with an explosive limit of 2.0 to 11.5 (volume). Toxic, LD504.16g/kg. The maximum allowable concentration in the workplace is 75mg/m3. It is highly corrosive and toxic, and has a strong irritation to the skin, eyes and respiratory tract. Inhalation of high concentrations of butyl acrylate can cause laryngeal edema, pulmonary edema, bronchitis, chemical pneumonia, and pulmonary edema. Ingestion can cause gastrointestinal burns, vomiting, and diarrhea.

3. butyl acrylate safety storage specification

1. storage place should be cool, ventilated, away from fire, heat source. The warehouse temperature should not exceed 30 ℃. Should be stored separately from the oxidant, do not mix storage. Not suitable for large or long-term storage. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
2. Fireworks are strictly prohibited. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear self-priming filtering gas mask (half mask), chemical safety goggles, anti-poison penetration overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidizing agents. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

4. Butyl Acrylate Safety Transport Specification

1. Transport vehicles should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. The exhaust pipe of the vehicle to which this product is shipped shall be equipped with a fire retardant device. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix and transport with oxidant, etc. During transportation, it shall be protected from sun exposure, rain and high temperature. Stay away from kindling and heat sources during stopover. The vehicles shall be thoroughly cleaned after transportation. It is forbidden to slip away during railway transportation.
2. Strictly sealed to provide adequate local exhaust and general ventilation. It is recommended that the operator wear a filtering gas mask (half mask), chemical safety goggles, anti-poison penetration overalls, and rubber and oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidizing agents. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

5. conclusion
Butyl
acrylate as an important raw material for chemical production, in the process of storage and transportation need to strictly abide by the relevant safety regulations to ensure the safety of personnel and the environment. By understanding its physical and chemical properties, safety storage and transportation specifications, we can effectively prevent accidents and ensure the safety of production.
