Reaction example 2
Reaction examples of anhydrous sodium sulfide
For the reaction which has a bad influence with water
For the reaction that requires high temperature of 100 ℃ or more
Low moisture content and high purity, it may lead to improvement in yield or selectivity.
| High purity | Over 98% purity of sodium sulfide has been realized with our original method. The high purity enables to suppress a drop in yields and control contamination. |
|---|---|
| Shape | Flaky shape is convenient for handling and keeping an operator free from the inhalation of the powder. Oxidation and water absorption proceed slowly due to the small specific surface area. |
| Cost efficiency | Pretreatment dehydration of sodium sulfide is not necessary for the reactions under aprotic conditions. Yield loss caused by a small amount of water can be suppressed, and thus, the reaction time and cost can be reduced. |
