DECHEMA contmues the pubhcauon of the Data Sents with Vol I, Part 2a Thts part covers 207 binary, ternary and quaternary systems from the Dortmund data bank with methanol, ethanol or I-propanol as one of the components Each bmary system IS represented by expcnmental data from a gwen bterature source, an equdiirmm dmgram, parameters of correlation equations and a list of devlatlons for eqmbbnum

“coal” (generaI aspects, Fischer-Tropsch-synthesis, gasdicatlon, hydrogenation, carbomzatlon. cokmg) could serve as a 282-paged monograph of coal technology, mcludlng 647 references up to 1977 It regards the recent developments m coal gasdicatlon and hydrogenation and describes 111detad all (pdot) plants m operatlon and under construchon, thus anhclpatmg processes of future unportance The keyword “hydrocarbons” covers the common aspects of this matter m addition to the keywords of the more unportant substances menttoned, which are referred to It sums up the methods of production and recovery, the properties as well as the separatton of hydrocarbons References to design procedures of mdusmal reactors carried out are mlssmg m general, but they have, to everybody’s regret, ranty value The “UlImann” continues to be the mdespensable work of reference for engmeers and chemists, which IS up to date (of Its publication) as far as possible It IS to be hoped, that the edltlon keeps its speed, thus the work wdl be completed m four years K
