摘要
二氧化硫脲 (简称 TD)的国内收率为 80 % ,产品成本高 ,利润低 ,通过对其现有生产工艺的改进 ,产品收率可达 88%～ 90 %以上 ,产品保质期也由原来的 1～ 3个月延长至 18～ 2
In our country,the thiourea dioxide(called TD for short) recovery rate is 80% and the cost of product is high and the profit of product is low.Based on improving the present process,the thiourea dioxide recovery rate can reach more than 88%～90% and the storage time of thiourea dioxide is prolonged from 1～3 months to 18～24 months.
