Reaction Steps

The invention further discloses a process of making colestipol carbonate and/or bicarbonate salt comprising: (a) reacting diethylene triamine hydrochloride with carbonate and/or bicarbonate ions to form diethylene triamine chloride, carbonate and/or bicarbonate salt; (b) reacting and copolymerizing the diethylene triamine chloride, carbonate and/or bicarbonate salt obtained in step (a) with a copolymerizing agent, in the presence of sodium hydroxide to form a wet gel; (c) reducing the particle size of the wet gel obtained in step (b); (d) purifying the wet gel particles obtained in step (c) with water to significantly remove the chloride ions; and (e) drying the purified gel particles obtained in step (d).
