Properties and stability
Toxic, irritating to human lungs and stomach. Because the product contains a small amount of chloroacetone, it has tear-inducing properties. Protective equipment should be worn during operation and should be replaced immediately if it is attached to clothing.
Storage method
For personal use, it is transported by pipeline; for export, it can be packed in iron drums.
Synthesis method
The preparation method is to add tetrachloropropane and ethanol into the reaction kettle, stir and heat to reflux, add potassium hydroxide in batches within 1 hour, complete the addition and reflux for 2 hours, cool and filter, and wash the filtrate twice with water. The water layer is extracted with dichloroethane, combined with the oil layer, desolvated, and distilled under reduced pressure. The 74-91°C/13.3 kPa fraction is collected as the finished product.
Purpose
Used as an intermediate for the herbicide oatmein.
It is mainly used as an intermediate for the pesticides and herbicides Avenida and Oatani No. 1, and is also a raw material for manufacturing special plastics.
