其他信息

急救治疗:眼睛用大量清水冲洗15分钟就医，皮肤应立即脱掉被污染的衣服，马上用大量的水冲洗。如果皮肤有刺激性反应，应马上就医。吸入要将病人转移到空气新鲜处，如果需要，咳补氧或进行人工呼吸。误食要冲洗口腔，喝1-2杯清水，不要催吐。无专用解毒剂。

用途二:氰胺是重要的农药中间体，可以制备杀菌剂多菌灵、苯菌灵、甲基嘧菌胺、嘧菌胺，杀虫剂抗蚜威、嘧啶氧磷，除草剂绿磺隆、甲磺隆、甲嘧磺隆、醚苯磺隆、苄嘧磺隆、吡嘧磺隆、环嗪酮等。
方法一:其制备方法是以石灰氮为原料，与硫酸作用而制得。在反应釜中投入水，以冰盐水冷却，投入石灰氮，保持温度在0～15℃之间，滴加5％硫酸溶液，调节pH＝6，保持20min，过滤、水洗，再返回反应釜中，再加入石灰氮，重复上述操作2次，将得到的过滤液进行薄膜浓缩，保持一定的温度，浓缩后含量达到50％～55％，得到50％氰胺溶液。反应方程式：CaCN 2 +H 2 O+H 2 SO 4 →NH 2 CN+CaSO 4

方法二:1.由石灰氮与硫酸反应而得。2.尿素法。
注意事项:过量的氰胺会伤害花芽，如浓度>6;%时。过早应用该药能使果实提前成熟2-6周，但产量可能会由于花期低温造成的落花和授粉不良而降低
