醇钠法是醇与碱金属的氢氧化物反应,生成碱金属的醇化物,然后与三氯氧磷反应得到。减压法是在减压条件下,醇与三氯氧磷直接反应,减压排出生成的HCL得到TOP。目前,我国TOP的生产工艺路线都是采用减压法,其工艺流程如下:将2-乙基乙醇加入反应釜,冷却降温至10℃以下,缓缓加入三氯氧磷,搅拌下进行反应,逐渐升温至60℃,用水泵抽出反应产生的氯化氢,反应完毕后加入10%碳酸钠溶液进行中和,再用80℃的水进行洗涤;采用真空水蒸气蒸馏的分离方法精制粗TOP,脱除2-乙基乙醇。分离磷酸三辛酯和TOP后,经吩咐过滤即得成品。 | |
可在蒽醌法生产过氧化氢中代替氢化萜松醇,使产品浓度高、质量好、自身消耗少用作阻燃剂、增塑剂、萃取剂。是一种既有阻燃性又有耐寒性的特种增塑剂,其低温性优于乙二酸酯类,耐水性优良,挥发性低,具有优异的凝胶作用,同时能赋予制品优良的机械性能、紫外光稳定性、抗老化性、阻然性及抑菌作用。主要应用于军用PVC制品、胶黏剂和涂料、合成橡胶及纤维中,还可以用于双氧水(H2 |
