Properties
Properties【外观性质】无色、易挥发液体, 有氨味。【溶解性】与水混溶,可混溶于醚、芳烃。【熔点 】−70 °C(lit.)【沸点 】134-136 °C(lit.)【密度 】0.886 g/mL at 20 °C(lit.)【蒸气压】100 mm Hg ( 55 °C)【折射率 】n20/D 1.4294(lit.)【闪点 】105 °F【储存条件 】Flammables area【水溶解性 】miscible【凝固点 】-59.0℃【Merck 】14,2843【BRN 】1209235【特性】N,N-二甲基乙醇胺DMEA(108-01-0)的催化活性很低,对泡沫上升和凝胶反应影响很小,但二甲基乙醇胺DMEA(108-01-0)的碱性较强,可以有效地中和发泡组分中的微量酸,特别是异氰酸酯中的酸分,因而就保住了体系中的其他胺。二甲基乙醇胺DMEA的这种低活性和高中和能力好比缓冲剂,在和三亚乙基二胺配合使用时特别有利,这样用低浓度的三亚乙基二胺就可以达到所需的反应速度。
