## Abstract The Soβcalled coal tar resins are defined and their preparation from vertical retort tar and pitch is described. The resins are divided into resinols, resinoic acids, resinenes, and resinamines, about 99% consisting of resinenes. The importance of dxygen in these compounds is discussed.
## Abstract Further work on resinenes is reported including hydrolysis, bromination, thermal decomposition, dehydrogenation, hydrogenation, and alk line permanganate oxidation. The resinenes give neutral and phenolic products on hydrolysis. Dehydrogenation with selenium gives neutral and phenolic p
