Abstract
Free uroporphyrin is decarboxylated by heating in the air to 150--200 degrees C. Complete decarboxylation occurs after heating to 200 degrees C for 5 min, with a yield of 66--75%. Heptacarboxylic porphyrin can be prepared with a yield of 40% by heating uroporphyrin to 150 degrees C for 60 min, and hexacarboxylic porphyrin with a yield of about 20% by heating to 150 degrees C for 2h.
摘要
游离尿卟啉在空气中加热至150 - 200℃时会发生脱羧反应。加热至200℃并保持5分钟后会发生完全脱羧，产率为66 - 75%。将尿卟啉加热至150℃并保持60分钟可制备出七羧酸卟啉，产率为40%；加热至150℃并保持2小时可制备出六羧酸卟啉，产率约为20%。
