WebA silicoaluminophosphate molecular sieve, CIT-16P, is synthesized using butane-1,4-bis(quinuclidinium) [(C7H13N)-(CH2)4-(NC7H13)]2+ dihydroxide (DiQ-C4-(OH)2) as an organic structure-directing agent (OSDA). Upon the removal of the OSDA, either by thermal treatment in air at temperatures exceeding 490 °C or by extended ozone treatment at 150 … WebFeb 1, 2024 · Exceptions were methionine and cysteine, containing an ozone-reactive sulfide or thiol group, respectively, which partially consume ozone via a fast reaction (von Sonntag and von Gunten, 2012). Since the sulfoxides are ozone-refractory, the sulfur reaction pathway of methionine is completed for 1 molar equivalent of ozone.
