Document Type and Number:
Japanese Patent JPH09249635
Kind Code:
A
Abstract:
To obtain the subject compound modified by specific surface treatment, low in toxicity and shock ignitability, thus useful as a component of gas generators for air bags.
This compound is obtained by surface treatment of (B) biscarbamoyl hydrazine by a conventional means with (A) an inorganic surface treating agent [pref. a water-soluble metal salt, such as AlCl3, NaAlO2, FeCl2 or FeCl3, among others, esp. pref. NaAlO2]. The amount of the component A to be used is 0.01-5wt.% or so (pref. 0.1-2.0wt.% or so) based on the whole amount of the component B.
