Properties and stability
As required It will not decompose or react when stored, keep away from oxides.
Storage method
This product should be sealed and stored in a cool, dry place.
Synthesis method
It is derived from the condensation of benzyl chloride and thiourea. Add benzyl chloride, thiourea and ethanol into the reactor to mix, heat to reflux, decolorize and filter after the reaction, cool and crystallize, then wash with ether and refine to obtain the finished product.
Purpose
Determination of cobalt and nickel. Detect and separate carboxylic, sulfinic and sulfonic acids. Standard for the determination of nitrogen, sulfur and chlorine in organic microanalyses.
