Preparation of aluminophosphate molecular sieves in the presence of nickel( II) and copper( II)
(Butterworth-Heinemann, 1991)
Nickel(ll)-substituted aluminophosphates of structure types 21 and 12 (NiAPO-21 and NiAPO-12) have been prepared hydrothermally in the presence of ethylenediamine as the template. U.v.-visible spectroscopy of NiAPO-21 ...
Synthesis and characterization of the CoSAPO- 14 and CoSAPO-34
(Butterworth Publishers, 1990)
The hydrothermal synthesis of CoSAPO-14 and CoSAPO-34 in the presence of isopropylamine as the template is described. CoSAPO-14 is a new MeSAPO material that predominantly forms at 125°C, whereas CoSAPO-34 is the main ...
The structure of CoSAPO-34, containing i-propylamine as a template
(Butterworth-Heinemann, 1991)
The crystal structure of a cobalt silicoaluminophosphate, CoSAPO-34, is reported. The crystals belong to the rhombohedral R3 space group with unit cell parameters a = 13.797(7) and c = 14.898(7) A. The final R index was ...
Formation of AlPO4-15 and CoAPO-15 in the presence of hexamethylenetetramine
(Butterworth-Heinemann, 1990)
Two materials, AIPO4-15 and CoAPO-15, with the same aluminophosphate lattice have been obtained by hydrothermal synthesis in the presence of hexamethylenetetramine (HMTA). Their formation is attributed to the influence of ...
A CoAPO-34 derived from a triclinic precursor prepared in the presence of HF
(Elsevier Science Inc., 1997)
The fluoride route of synthesis of AIPO,-34 is also successful in the preparation of its cobalt modified product (CoAPO-34). The triclinic precursor of CoAPO-34 has been synthesized in the presence of HF and piperidine. ...
A novel open framework zincophosphate: Synthesis and characterization
(Elsevier Science Inc., 1995)
The crystallization of a reactive zincophosphate gel (which may contain Co(ll) component) in the presence of sodium cations at ambient temperature and pressure yielded products (abbreviated ZnPO-HEX or CoZnPO-HEX) with a ...
On the possibility of the preparation open framework manganese phosphate
(Elsevier Inc., 1996)
Manganese(ll)/phosphate/organic template hydrothermal reactions were investigated with the aim of preparing novel crystalline porous materials. Ethylenediamine, isopropylamine, and piperidine were explored as organics that ...
