Open the CIPO recordAbstract From the Canadian patent
A method for the synthesis of the silicoaluminophosphate SAPO-37 comprises preparing a two-phase reaction mixture containing the required starting materials divided between a liquid organic phase and a liquid aqueous-phase. The reaction mixture is then heated at a rate of from 5°C to 200°C per hour to a temperature of from 80°C to 200°, while being agitated in a manner sufficient to intimately admix the liquid organic and aqueous phases. Once nucleation of the silicoaluminophosphate occurs the agitated reaction mixture is heated at rate of from 5°C to 200°C per hour to a temperature of from 100°C to 300° and maintained then at the higher temperature and at a pH of from 2 to 9 until crystals …
