Abstract:The batch synthesis of thiourea dioxide(TD) in an aqueous solvent was changed to a continuous pipe-style process in this paper.The influences of the feed rate of the raw materials,reactant concentration and the quantity of the promoter,ammonium bicarbonate on the performance of TD synthesis were investigated.Through experimental study,the suitable reaction conditions such as the reaction temperature,raw material ratio,reaction time,reactant concentration,etc.were obtained.Under the suitable conditions,the yield and purity of TD product were higher than 80% and 99%,respectively.
Keywords:thiourea  thiourea dioxide  continuous reaction technology  pipe reactor
