Ethylene ketals of the type (I) cyclise in presence of phosphorus pentoxide in pyrid& to give the ketal (II) which on hydrolysis yields l-phenyl-6:7-dimethoxy4oxo-3:4-dihydroisquinob (III). 1-(4-oxo-cyclohexyl)-6:7-dimethoxy-3:4-dihydroisoquinoline (Vlll) and 2-oxo-3-methyl-g:1& dimethoxy-I 2:3:4:6:
## Abstract Data presented for a range of vulcanized rubbers prepared under different conditions show that while olefinic unsaturation becomes reduced by vulcanization in the proportion of one double bond for each sulphur atom combined with a C~5~Hβunit, the original H/C ratio of 8/5 is not altered
When potassium ferrocyanide is titrated with zinc ions, K2Zn3[Fe(CN)6]2 is formed only slowly and hence only one end-point is observed corresponding to a combining ratio of 2 : 1. In highly concentrated solutions of K4Fe(CN)6 the formation of K2Zna[Fe(CN)6]2 is rapid and hence a 1.5 : 1 ratio is obt
