## Abstract The 220 MHz proton magnetic resonance spectrum of 4βmethylβ1,3βoxathiolane was recorded and analysed. The methyl and ethanic protons form an ABXM~3~ system, the analysis of which was carried out through several βtrialβandβerrorβ attempts. This part of the spectrum is an interesting exam

than the initial fraction, which contains more aliphatic and hydroaromatic material. Proton n.m.r. data are consistent with these aromaticity results. ## Conclusions The initial results reported here from tests in the FDU using both coal-derived distillate and residuum show that the unit is basic
Whereas simple 4,4Π-bi(1,3-dioxanyl)s 16 and 19 displayed little conformational preference at the inter-ring bond, their derivatives 4 and 13, with equatorial methyl groups in the 5and 5Π-positions, each showed a strong conformational preference to populate a conformation with a gauche arrangement o
