What is Triacetonediamine?

Chemical properties

CLEAR SLIGHTLY YELLOW LIQUID

The Uses of Triacetonediamine

Triacetonediamine have been investigated as new anticancer drugs with high activity and low toxicity.

The Uses of Triacetonediamine

Additive for light and heat stability of polyamide 6 containing hindered piperidine amines and tertiary amines

Template for preparation of ammoniopiperidinium hydrogen phosphates

Fiber-reactive yellowing inhibitor for partial brightness stabilization of peroxide-bleached pulps

Reactant for thermostability of soybean / sunflower oils

Preparation

Triacetonediamine is formed by the poly-aldol condensation of acetone in the presence of ammonia and calcium chloride: 3 (CH3)2CO + NH3 → OC(CH2CMe2)2NH + 2 H2O

Reactions

Triacetonediamine is an intermediate in the preparation of 2,2,6,6-tetramethylpiperidine, a sterically hindered base and precursor to the reagent called TEMPO. Reductive amination of triacetonamine gives 4-amino-2,2,6,6-tetramethylpiperidine.

Safety Profile

Moderately toxic by ingestion.When heated to decomposition it emits toxic vapors ofNOx.
