Study on the Synthesis of a Dichlorotriazinyl Reactive Dye and Some of its Dyeing Properties
Dichlorotriazinyl 반응성 염료의 합성과 그의 염색성 에 관한 연구
Abstract
A synthesis of dichlorotrizinyl reactive dye with cyanuric chloride as reactive component was studied, and the hydrolysis rate of dye and the dyeing properties were also discussed. The yield of the dye was 80% and its colour was bright red. The pseudo first order rate constant of hydrolysis was calculated in buffer solutions of PH 11 and PH 9. The maximum amount of exhaustion on cotton was obtained, when Na
Dichlorotriazinyl형 반응성 염료를 합성하기 위하여 cyanuric chloride를 H-acid의 아미노기와 반응시켜 얻은 화합물에 p-nitroaniline을 diazo화 하였다. 아울러 합성한 염료의 가수분해속도와 면섬유 및 견섬유에 대한 염색성을 조사하여 다음과 같은 결과를 얻었다. 1. 얻어진 반응성 염료는 저온에서 쉽게 합성 할 수 있었으며, 수율은 80%였다. 2. 면섬유에의 흡진량은 황산나트륨 30g/ι를 첨가하였을때 최대이었으며 고착량은
