摘要： Glowing coke descending through a cooling duct in a coking plant is quenched by two gas flows respectively traversing an upper compartment and a lower compartment of the duct, the two compartments meeting at a restricted gate for the passage of the coke. At least the lower gas flow, passing in countercurrent to the descending coke charge, is also circulated through a drying and preheating oven for coal to be fed to a coke-oven battery of the plant, thus containing some water vapor. When the upper flow is also constituted by coal-drying gas, it is passed downward through the upper compartment in order to reduce the height of a high-temperature zone in which combustion and thus loss of coke could occur. The coke gate is formed by a funnel-shaped upper partition and an upwardly pointing conical lower partition between which a scavenger gas passes in cross-flow.

摘要： Cyclic methyl fumaraldehyde monoacetals and a process for their production by oxidation of the corresponding methylbut-2-en-4-ol-1-al acetal with an H.sub.2 SO.sub.4 -containing solution of chromic acid in acetone. The new compounds are of considerable interest as intermediates in the synthesis of carotinoids.

摘要： 2(OR 3)-Methyl-1-acetoxy-4-alkoxy(or phenoxy)-1,3-butadienes and a process for their manufacture. The new 2(or 3)-methyl-1-acetoxy-4-alkoxy(or phenoxy)-1,3-butadienes are obtained by heating the corresponding methyl-4-alkoxy(or phenoxy)-crotonaldehyde with an excess of acetic anhydride and an alkali metal acetate, alkali metal carbonate or alkali metal hydroxide or a non-aromatic bicyclic amine or by heating the corresponding methyl-1-acetoxy-4,4-dialkoxy-2-butene in the presence of p-toluenesulfonic acid and quinoline at a temperature of from 150.degree. to 260.degree. C. The new compounds are of very considerable importance as intermediates in the synthesis of carotenoids.
