    摘要: The cobalt carbonyl catalyst R.sup.5 CCo.sub.3 (CO).sub.9, desirably with Ru.sub.3 (CO).sub.12, wherein R.sup.5 is hydrogen; alkyl, preferably C.sub.1-5 lower alkyl; cycloalkyl or substituted cycloalkyl; cycloalkenyl, such as cyclohexenyl or cyclooctenyl; C.sub.1-12 alkoxy, such as methoxy or propoxy; aryl or alkyl-, cycloalkyl-, alkoxy-, halo-, or cyano-substituted aryl; cyano; or a silyl carbyne moiety of the formula R.sub.3.sup.6 Si, wherein R.sup.6 is alkyl or aryl, effectively catalyzes the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers. Methylal, for example, may be reacted with syngas; i.e., CO and H.sub.2, in the presence of this catalyst system to form the corresponding ethylene glycol monomethyl ether.The novel catalyst combination of R.sup.5 CCo.sub.3 (CO).sub.9 and Ru.sub.3 (CO).sub.12 is likewise claimed herein.

    摘要: The removal of color bodies from an olefinic or saturated endo-endo hexacyclic homodimer of norbornadiene or mixtures thereof is accomplished by the use of a serpentine clay. Also acid bentonite clay or a montmorillonite clay can be used to remove the color bodies from the saturated dimer. The saturated dimer has a high density and a high heat of combustion making it useful as a missile fuel. Removal of the color bodies avoids possible catalyst poisoning in the hydrogenation of the olefinic to the saturated dimer. Also removal of the color bodies from the saturated dimer eliminates the possible problem of a material precipitating out on engine turbine blades and causing maintenance or operational problems.
