WebThe invention discloses a method of preparing amino trimethylene phosphonic acid by virtue of triformol. The method concretely comprises the steps: with phosphorous acid, ammonium chloride and the triformol as raw materials, adding the phosphorous acid and the ammonium chloride into a reaction kettle to be heated firstly, then adding the triformol in … Trimethylene carbonate, or 1,3-propylene carbonate, is a 6-membered cyclic carbonate ester. It is a colourless solid that upon heating or catalytic ring-opening converts to poly(trimethylene carbonate) (PTMC). Such polymers are called aliphatic polycarbonates and are of interest for potential biomedical applications. An isomeric derivative is propylene carbonate, a colourless liquid that does not spontaneously polymerize.
