IMPROVED METHOD FOR THE DETERMINATION OF THE OXYGEN ISOTOPIC COMPOSITION OF CELLULOSE

A modification of a chemical preparation procedure for oxygen isotope analysis of cellulose has been developed which yields greater precision and requires less time for sample preparation. In the place of isoquinoline, zinc is used to remove HCl from the reaction products of the sample and HgCl2. The two methods give systematically different results because isoquinoline biases measurements by contaminating the sample with additional CO2. For the zinc method, precision is +/-0.2 parts per thousand (1 sigma standard deviation) compared with +/-0.9 parts per thousand for the isoquinoline method.

Decomposition of isoquinoline and quinoline by supercritical water

The ability of supercritical water (SCW) to decompose heterocyclic compounds (quinoline and isoquinoline) has been explored in this study. The results obtained suggest that water acts as a chemical reagent above its critical point (374 degrees C and 22.1 MPa). Significant proportions of isoquinoline and quinoline were removed during the reaction with SCW. The response of these compounds to pyrolysis was also compared with their reaction with SCW. Both compounds were relatively more reactive in the presence of SCW than during pyrolysis. Because of the different positions of N atom in the two compounds, they reacted with SCW differently. Breaking of C-N bonds during SCW reaction was by hydrogenation and hydrocracking, while pyrolysis was due to thermocracking mainly. (C) 2000 Elsevier Science B.V. All rights reserved.

Isoquinoline

Isoquinoline, C9H7N, is a ligand which is used as a complexing agent for different metals. In order to compare geometric features of free isoquinoline and isoquinoline as a complexing ligand, we determined its crystal structure. Regrettably, the molecule is located on a centre of inversion and is therefore disordered; it is also isostructural with naphthalene. By refinement experiments and packing considerations, we were able to discard the possibility of fourfold disorder, which has been found for several beta-substituted naphthalene compounds, and performed the structure determination employing a model of twofold disorder.
