    • The present invention relates to a process for producing a solid sodium diformate preparation having a formic acid content of at least 35% by weight based on the total weight of sodium diformate preparation, in which, at elevated temperature, an aqueous solution (E) is produced which comprises sodium formate and formic acid in a molar ratio of HCOOH:HCOONa of greater than 1.5:1 and which has a molar ratio of HCOOH:H2O of at least 1.1:1, the aqueous solution (E) is brought to crystallization to obtain a solid phase (F) and a mother liquor (G), and the solid phase (F) is separated off from the mother liquor (G), (i) the mother liquor (G) being fed to a distillation apparatus (DV); (ii) the mother liquor (G) in the distillation apparatus (DV) being admixed with a sodium-comprising base (A) to obtain a mixture (B) comprising sodium formate and formic acid; (iii) admixing the mixture (B) obtained from step (ii) with formic acid (D) to obtain the aqueous solution (E); and (iv) excess water (C) essentially being ejected only by withdrawal from the distillation apparatus (DV); and also to the use of a solid sodium diformate preparation obtainable by the inventive process as feed additive for animal feed, in particular for monogastric animal feed and especially for animal feed for hogs and/or poultry.

    • In order to prepare thermoplastic molding materials ofA) 5-95% by weight of a modified polyphenylene ether,B) 5 to 95% by weight of a thermoplastic polyamide,C) 0 to 25% by weight of an impact-modifying rubber, andD) 0 to 50% by weight of auxiliaries and/or additives,the components A and B and if necessary the components C and D are fed individually at one or more points into an extruder, mixed with one another, and melted. The component A present in a pulverulent consistency is compacted and/or sintered under pressure and if necessary with the addition of heat, preferably at a pressure corresponding to a nip pressure of 1 to 100 kn/cm to form a porous compact before it is fed into the extruder. The compact is then modified and added as granules to the feed zone of the extruder. In this way the proportion of the fines in the polyphenylene ether is considerably reduced, so that there is virtually no further danger of dust explosions. Further advantages include an improved ease of metering and reduced electrostatic charge.
    • 为了制备A)5-95重量%的改性聚苯醚的热塑性成型材料,B)5-95重量%的热塑性聚酰胺,C)0-25重量%的抗冲击改性橡胶, 和D)0至50重量%的助剂和/或添加剂,组分A和B以及组分C和D如果需要,在一个或多个点分别进料到彼此混合并熔化的挤出机中。 存在粉碎稠度的组分A在压力下压实和/或烧结,如果需要加热,优选在相当于1至100kn / cm的压区压力的压力下形成多孔压块,然后再进料 进入挤出机。 然后将压块改性并作为颗粒加入挤出机的进料区。 以这种方式,聚苯醚中细粉的比例大大降低,实际上没有进一步的粉尘爆炸危险。 另外的优点包括改进的计量方便性和减少的静电电荷。
