## Abstract A highly crystalline ZSMβ5 product was obtained from diatomite, a natural raw material, both with and without the presence of diethanolamine. The synthesis process took 40 h, and was carried out under hydrothermal conditions, at autogenic pressure, and at a temperature of 180 Β°C. The re
a-Formylc~clo/iexurtrune: A solution of 73 g of dimethylforniamide in 300 g of dichloromethane is stirred with exclusion of moisture at 5-10Β°C, and a solution of 100 g of phosgene in 300 g of dichloromethane is added dropwise. The mixture is left standing for 3 h, and then 167 g of I-morpholinocyclo
