Abstract

Abstract Synthesis of some azoic dyes based on a-naphthol requires special conditions such as low temperature, use of dense acids and high pressure. Aside from great expenses and difficulties in preparing conditions of solution, depreciation of dye-making devices due to the application of dense acids is regarded as another problem in this system. This paper tries to use a new method to remove these difficulties. Producing dyes using solid acids ...
