摘要:The present invention relates to a process for the deprotection of protected amine compounds, wherein the protected amine compound is contacted with an electrophilic oxidating agent that is optionally formed in situ, said electrophilic oxidating agent being selected from the group of I 2 , Br 2 , Cl 2 and compounds comprising a halogen atom having a formal oxidation state of 1+, 3+, 5+ or 7+, provided that the electrophilic oxidating agent is not iodobenzene diacetate. The process can be conveniently employed in the synthesis of 1,3-amino alcohols, β-amino acids and heterocyclic compounds, in particular β-amino acids.

标题:Synthesis of zeolites of small and uniform size having a high magnesium exchange capacity
发明人：KOSTINKO JOHN A
权利人:HUBER CORP J M
摘要:Zeolites of small and uniform size are formed having high magnesium exchange capacities. Zeolite A is disclosed having an average particle size less than 1.7 microns, a calcium carbonate exchange capacity of more than 230 mg calcium carbonate per gram zeolite and a magnesium exchange capacity of more than 140 mg magnesium carbonate per gram zeolite. This zeolite A is produced from a reaction mixture having a water to sodium oxide molar ratio of less than 35:1, and a sodium oxide to silica molar ratio of between 1:1 and 4:1, wherein the silica to alumina molar ratio is greater than 3:1 when the sodium oxide to silica molar ratio is less than 4:3 and the sodium oxide to alumina molar ratio is greater than 4:1 when the sodium oxide to silica molar ratio is greater than 4:3. Zeolite X is disclosed having an average particle size less than 2.2 microns, a calcium carbonate exchange capacity of more than 205 mg calcium carbonate per gram zeolite, and a magnesium exchange capacity of more than 130 mg magnesium carbonate per gram zeolite. This zeolite X is produced from a reaction mixture having a silicate alumina molar ratio greater than 5:1. A combination of zerolite A and zeolite X can be produced from the same reaction mixture.
