摘　　要：热重法对含羧甲磺酰基偶氮染料的脱羧动力学研究匡春香，潘鑫（大连理工大学化工学院大连１１６０１２）杨青（辽宁师范大学化学系大连１１６０２２）关键词热重法，染料，脱羧，动力学本文用热重法研究了四支含羧甲磺酰基偶氮染料（Ⅰ～Ⅳ）的脱羧反应，获得了脱羧温度，...Thermogravimetry was used to study the decarbexylation reaction of four azo-dyes containingcarboxymethylsulfonyl group (D-SO_2CH_2COOH). Decarboxylation temperatures were thusobtained. Kinetic parameter and kinetic compensation effect were also determined by approwimateintegral method and Avrami-Erofeev equation.
