Rapidly hydrolyzes in water to dimethylamine, carbon dioxide and hydrochloric acid; its half-life at 0 C is about 6 min. Sensitive to moisture.

Storage location should be close to laboratory where it is to be used, so that only small amounts need to be transported. Carcinogens should be kept in only one section of storage area, explosion-proof refrigerator or freezer as required. The area should b

<p>由二甲胺与光气反应制得,反应式如下: 将甲苯加入反应锅内,在冷却的条件下通入光气吸收至计算量。在另一锅中由二甲胺水溶液发生气体二甲胺,经干燥后通入光气甲苯溶液中反应。反应结束后过滤除去盐酸盐,减压蒸馏,收集75(3.33kPa)馏分即为二甲氨基甲酰氯,收率55%。 另外,二甲氨基甲酰氯还可以由N,N-二甲基甲酰胺与三氯化磷反应后再与氯化亚砜制得。或者以Pd,PdCl2或RhCl3为催化剂,由二甲基氯化铵与一氧化碳直接反应得到。</p>

<p>用作医药、农药、染料、塑料、合成材料及其他精细有机化工产品的合成,例如用于生产溴化新期的明、甲基硫酸新斯的明、吡啶斯的明,氨基甲酸酯类杀虫剂等。还用作溶剂。</p>
