摘　　要：研究Pt/C催化剂应用于彩色显影剂CD-3的生产工艺。采用高压釜,Pt/C作催化剂,催化加氢还原亚硝基物,随后与硫酸成盐制备彩色显影剂CD-3,加氢转化率>99%,纯度>99%。The production process of color developer CD-3 with PC catalyst was studied.Using a high-pressure reactor,P/C as catalyst,the nitroso is reduced by hydrogenation,and then color developer CD-3 was prepared in form of sulfate with sulfuric acid.The hydrogenation conversion rate>99% and the purity of CD-3>99%.

关 键 词：加氢还原 PT/C催化剂 彩色显影剂CD-3
