Properties and stability
1. Stable under normal temperature and pressure.
2. This product is toxic and irritating. Inhalation of dust can cause acute poisoning. Symptoms include wheezing, periodic vomiting, cyanosis, and convulsions. Severe cases show loss of will, and protein, sugar and a small amount of red blood cells can be detected in the urine. Operators should wear gas masks or masks.
Storage method
Save in a sealed and dry place, away from oxidants.
This product is packed in a sturdy wooden box, barrel or plastic barrel lined with plastic bags or kraft paper bags and should be packed tightly. The outside of the box is tied tightly with iron wire and iron sheets. The net weight of each piece should not exceed 50kg and should be stored away from light.
Synthesis method
Produced by the reaction of carbon disulfide, ethanol and sodium hydroxide.
Purpose
1. Used as collector for non-ferrous metal ore flotation.
2. Used for drying crops in agriculture, suitable for rice.Wheat, etc. Spraying at an appropriate period before harvest can quickly reduce the moisture content of the grain husks, accelerate drying, and facilitate threshing. Industrially used to make leprosy medicine, rubber vulcanization accelerator, etc. Molybdenum reagent. Ore flotation agent.
