Beschreibung

Anwendung

Trimethylamine (TMA) has been used in the preparation of poly[9,9′-bis(6′-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), a water-soluble, cationic conjugated polymer used in label-free DNA microarrays. It can also be used to prepare benzyltrimethylammonium chloride, which then reacts with sodium ethoxide to form benzyltrimethylammonium ethoxide. The adsorption of TMA on the gold surface of trimethylsilylated barium nitrate-gold/titanosilicate catalyst acts as a promoter for the propylene epoxidation with oxygen and hydrogen.
