    摘要: A process for preparing 2,4-dichloro-5-dichloromethyl-thiazole of the formula ##STR1## which comprises reacting 2,4-dichloro-5-thiazole-carboxaldehyde of the formula ##STR2## with thionyl chloride (SOCl.sub.2) in the presence of a halogenating catalyst at a temperature between 0.degree. C. and 100.degree. C. Preferred catalysts are aprotic organic nitrogen or phosphorus compounds. The products are directly obtained in high yield and purity so they can be directly used as bactericides or as intermediates for herbicides.

    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: To increase the temperature at which a tar separator operates which separates tar from condensate obtained by cooling coking gas produced by coking preheated coal, the condensate is preheated by heat exchange with the coking gas entering a raw gas cooler and is then admitted into the coking gas collecting main of the coking ovens, from which it passes to the tar separator. A method and an apparatus are disclosed.
