随着工农业生产的发展,泡沫塑料生产发展得很快,塑料制品已广泛应用于各个部门。具有毒性的甲苯二异氰酸酯是合成聚氨酯塑料——泡沫塑料的主要原料之一。实际上有微量甲苯二异氰酸酯溶解于水中,为了解其含量,需进行定量分析。关于水中甲苯二异氰酸酯的分析方法,目前还未见报导,我们依据参考资料,经过多次实践检验,拟制了水中甲苯二异氰酸酯定量测定法,结果较满意,现将方法介
With the development of industrial and agricultural production, foam production has developed rapidly, plastic products have been widely used in various departments. Toluene diisocyanate is toxic one of the main raw materials for synthetic polyurethane plastic foam. In fact, a trace amount of toluene diisocyanate dissolved in water, in order to understand its content, the need for quantitative analysis. Toluene diisocyanate in water analysis methods, has not yet been reported, we based on reference materials, after many practice tests, prepared in water toluene diisocyanate quantitative determination method, the results are satisfactory, the method described
