农药“二硝散”(二硝基硫氰代苯)是二硝基氯化苯、硫氰酸銨及乙醇的縮合物,其化学构造式为2·4·—二硝基—1—硫氰代苯,是一种淡黄結晶体,分子量225.19,溶点139℃,呈中性,遇酸稳定,遇鹼易破坏,不溶于水而易溶于乙醇、甲醇、氯仿、苯,氯苯二甲苯、丙酮等有机溶媒及矿物油中,經过加工可装成粉剂,可湿剂或乳剂,可以防治葡萄霜霉病,苹果黑星病,疮痂病,麦类的锈病,赤霉病,白粉病,稻白叶枯病,瓜类和菜类的炭疽病等。我们調查了一个农药厂的“二硝散”生产車間,对34名患接触性皮炎的工人进行治疗,其中7例病情較重而住院治疗,現报告于下。病例分析 1.由从事工作到发病时间,最长者为25天,最短为3天,平均約14天。
Pesticide “two nitrification” (DNTB) is dinitrochlorobenzene, ammonium thiocyanate and ethanol condensate, the chemical formula for the 2.4 · - dinitro-1-sulfur Cyanobenzene, a pale yellow crystal, has a molecular weight of 225.19 and a melting point of 139 ° C. It is neutral, meets acid stability, is easily broken by alkali, insoluble in water and soluble in ethanol, methanol, chloroform, benzene and chlorobenzene Xylene, acetone and other organic solvents and mineral oil, after processing can be loaded into powder, wettable agent or emulsion, you can control grape downy mildew, apple scab, scab, wheat rust, scab, Powdery mildew, rice leaf blight, anthracnose of melons and vegetables. We surveyed a pesticide plant’s “two-nitrous” workshop to treat 34 workers with contact dermatitis, seven of whom were seriously ill and hospitalized, are reported below. Case Analysis 1. From the work to the onset time, the longest 25 days, the shortest is 3 days, an average of about 14 days.
