摘要： 4,6-Dichloropyrimidines are obtained by the reaction of 4,6-dihydroxypyrimidines with excess phosphoryl chloride in a particularly advantageous manner when no base is added, during and/or after the reaction 0.75 to 1.5 mol of phosphorus trichloride and 0.7 to 1.3 mol of chlorine are added per equivalent of exchanged hydroxyl groups so that an excess of phosphorus trichloride with respect to chlorine is always present, and finally phosphorus trichloride and phosphoryl chloride are separated off. This process can be carried out in a particularly simple manner and also continuously.

摘要： In the production of thiocarbohydrazide by reacting hydrazine hydrate with carbon disulphide in the presence of water to form in a first stage hydrazinium dithiocarbazinate, subsequently thermally decomposing the hydrazinium dithiocarbazinate in a second stage to form thiocarbohydrazide, and recovering the thiocarbohydrazide from the reaction medium, the improvement which comprises effecting the entire reaction in the mother liquor of a preceding batch, carrying out the first reaction stage at a temperature between about 25.degree. C. and 45.degree. C., with injection of carbon disulphide below the surface of the reaction mixture; carrying out the second stage at about 62.degree. to 65.degree. C. without prior isolation of the intermediate product; filtering off the thiocarbohydrazide formed after cooling, separating the amount of mother liquor in excess of that required for the next batch, and feeding the balance of the mother liquor to the next batch. The excess mother liquor not required for the next batch is heated to about 70.degree. to 75.degree. C., and after separating off the thiocarbohydrazide, the remaining mother liquor is subjected to combustion.
