过氧化尿素是一种高效、多功能固体消毒剂。本文研究了合成过氧化尿素用的稳定剂。考察了反应温度及稳定剂对过碳酰胺转化率和纯度的影响。实验发现稳定剂后,产品的纯度均有所改善,其中以EDTA(2Na)、酒石酸效果最为明显。而稳定剂的加入量对反应转化率无明显影响。 Urea peroxide is an efficient, versatile solid disinfectant. This article studies the synthesis of urea peroxide stabilizer. The effects of reaction temperature and stabilizer on the yield and purity of percarbamide were investigated. After the experiment found that the stabilizer, the purity of the product has improved, of which EDTA (2Na), tartaric acid effect is most obvious. The addition of stabilizer has no significant effect on the reaction conversion rate.
