Processes for preparing a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions, and textile compositions.
制备炭黑产品的工艺,炭黑上附有有机基团。在一种工艺中,至少一种重氮盐在没有足以还原重氮盐的外加电流的情况下与炭黑反应。在另一种工艺中,至少一种重氮盐与炭黑在质子反应介质中发生反应。描述了根据本发明工艺可制备的炭黑产品,以及此类炭黑产品在塑料组合物、橡胶组合物、纸张组合物和纺织组合物中的用途。
