Structural characteristics of hazardous organic matter (2)

Case 2

Intramolecular or intermolecular reactions cause explosion or flushing:

At 0°C, benzylamine was added to the anhydrous ether solution of compound A, and then the pentane solution of titanium tetrachloride was added dropwise

As a result, about 1 hour after the oily product B was obtained, the bottle containing the product exploded

Reason analysis: There are two reactive sites of δ ⁺ and δ ^-which can react with each other in the molecule of product B , which is prone to an exothermic polymerization reaction between molecules

Remarks: Note that the product contains more than two active centers that can react with each other.

Case 3

A R&D personnel conducts an amine transesterification reaction:

After the reaction, the pH is adjusted and the product precipitates.

Reason analysis: The product is an unstable dangerous compound with four chemically active sites
