    • PURPOSE: Provided is a process for producing a sulfonated solid particle which is conducted under mild conditions without using solvents and whose reactions are readily controlled. CONSTITUTION: The process for producing a sulfonated solid particle includes the steps of: burning sulfur to yield gaseous sulfur dioxide; catalytically oxidizing the gaseous sulfur dioxide to yield gaseous sulfur trioxide; and sulfonating a dry powdery or granular solid particle with the gaseous sulfur trioxide in a gas phase-solid phase reaction. In the sulfonating step, a gaseous mixture of the gaseous sulfur trioxide with a gas inert to the gaseous sulfur trioxide and the solid particle is used. The solid particle is at least one selected from the group consisting of organic pigments, carbon black pigments, conductive carbon black, carbon black for use in batteries, carbon black for use in rubber, water-insoluble dyes, and resinous fine particles.
    • 目的:提供在温和条件下不使用溶剂进行磺化固体颗粒的方法,其反应容易控制。 构成:生产磺化固体颗粒的方法包括以下步骤:燃烧硫以产生气态二氧化硫; 催化氧化气态二氧化硫以产生气态三氧化硫; 并在气相 - 固相反应中用气态三氧化硫磺化干粉状或颗粒状固体颗粒。 在磺化步骤中,使用气态三氧化硫与气态三氧化硫惰性气体和固体颗粒的气态混合物。 固体颗粒是选自有机颜料,炭黑颜料,导电炭黑,电池用炭黑,炭黑,水不溶性染料,树脂微粒等中的至少一种。
