✦ Synopsis

We report results of small-angle neutron scattering (SANS) measurements on aqueous solutions of 1,7-heptanediol in the molarity range 0.11-1.5 mol dm À3 at room temperature. The experimental data show aggregation of the diol molecules within the whole studied concentration range. The scattering curves could be accurately described by the structural model of random concentration fluctuations. The results suggest that 1,7-heptanediol molecules in aqueous solution aggregate in a rather loose way.

Three perdeutero-pyridine extracts of Illinois No. 6 coal were studied with SANS in an effort to: 1. check the reproducibility of the measurements; 2. check the reproducibility of the extractions; and 3. try to measure weight average molecular weights for the non-fractionated extracts. In addition o
