Overview

Acetyl chloride is a colorless to pale yellow liquid with a strong pungent odor and is highly volatile at room temperature. Its vapor not only has strong corrosiveness to the eyes, skin, and respiratory tract, but also belongs to flammable and explosive gases. Therefore, manual inspection alone is far from enough, and fixed online monitoring equipment must be deployed. The fixed online monitoring and alarm detector for chloroacetyl gas continuously monitors the concentration of C ₂ H ∝ ClO vapor in the air through high-precision ECD electrochemical or PID sensors, which can meet the monitoring and safety alarm needs of chloroacetyl gas leakage in places such as medicine, electroplating, and chemical industry.

固定式氯乙酰气体在线监测报警探测器

Acetyl chloride (chloroacetyl) is a colorless fuming liquid with a boiling point of only 51 ℃. It undergoes severe hydrolysis to produce HCL and acetic acid when exposed to water or humid air, and has a strong corrosive and irritating odor. According to the Occupational Exposure Limits for Hazardous Factors in the Workplace Part 1: Chemical Hazardous Factors (GBZ 2.1-2019), the time weighted average allowable concentration (PC-TWA) of acetyl chloride in the workplace air is 0.5 mg/m ³, and the short-term exposure allowable concentration (PC-STEL) is 1.5 mg/m ³. Once leaked, low concentrations can cause respiratory burns and skin irritation, while high concentrations may lead to pulmonary edema and even endanger life. For scenarios where acetyl chloride is used in chemical synthesis, pharmaceutical intermediate production, pesticide manufacturing, etc., a fixed online detection and alarm system that can "watch around the clock and shout when it exceeds the standard" is a must-have.

Taking the ERU-PG51SACL fixed online acetyl chloride (chloroacetyl) gas detection alarm of Yingrun Group as an example, its sensor is specifically optimized for acetyl chloride gas. When acetyl chloride gas in the environment diffuses into the sensor, specific chemical reactions or changes in conductivity occur, resulting in an electrical signal proportional to the gas concentration. The signal is analyzed by a built-in high-precision amplification and data processing circuit, and converted into concentration values in real-time (usually in ppm or mg/m ³), which are displayed on the on-site LCD screen or remote monitoring system.

Fixed online acetyl chloride (chloroacetyl) gas detection alarm product features:

Typical applications of fixed online acetyl chloride (chloroacetyl) gas detection alarm:

▲Production of pesticides/plant protection chemicals

Manufacturing or storing reagents containing acyl chlorides and acetylation requires strict requirements for volatile gases.

▲Synthesis of pharmaceutical and chemical intermediates

Acetyl chloride reaction and synthesis process may release acetyl chloride vapor, which needs to be closely monitored.

▲Electroplating materials/catalysts/dyes/organic synthesis plants

There is a risk of volatilization or leakage when using chloroacetyl reagents/raw materials.

▲Storage and transportation warehouse

If the liquid or gas of acetyl chloride evaporates, it needs to be monitored for a long time to prevent exceeding the standard.
