摘要
乙二醇与甲醇类防冻液被广泛应用于内燃机的冷却系统,但具有较大的环境危害性。作为一种环境友好型可再生资源,甘油也可以大大降低水的凝固点。文章利用差示扫描量热法测定了一定量甘油对乙二醇/水、甲醇/水体系凝固点的影响,对新型环境友好型防冻液的发展具有重要的参考价值。
Ethylene glycol and methanol, widely used in the cooling system of the internal combustion engine, have potentially serious environmental dangers. As an environmentally friendly and renewable resource, glycerol can also be applied to prepare antifreeze. In the paper, the effects of glycerol on freezing point of ethylene glycol/H2O and methanol/H2O systems are studied by differential scanning calorimetry, which will provide the reference for the development of the environmentally friendly antifreeze.
