SYNTHESIS METHOD FOR LITHIUM CARBODIIMIDE
Document Type and Number:
WIPO Patent Application WO/2024/077671
Kind Code:
A1
Abstract:
The present application provides a synthesis method for lithium carbodiimide, comprising the following steps: reacting lithium hydride and a carbon source substance in a nitrogen atmosphere to obtain lithium carbodiimide. The present invention uses abundant and cheap nitrogen molecules as a nitrogen source to prepare lithium carbodiimide. The prepared lithium carbodiimide has high purity. The preparation process is simple, easy to scale u, and does not require further separation and purification.
