季戊四醇
pentaerythritol,tetramethylol methane
c(ch2oh)4 白色结晶,熔点261~262℃。是 b.托伦斯在1882年研究氢氧化钡与不纯的甲醛之间的反应时首先发现的。1891年托伦斯进一步指出它是甲醛与乙醛的反应产物。1938年美国开始用甲醛和乙醛生产季戊四醇。此法迄今仍是工业上采用的唯一方法。在碱性溶液中,甲醛与乙醛发生下列反应:
(hoch2)3ccho+hcho+naoh─→c(ch2oh)4+hcoona
前一反应是可逆的,以碱为催化剂;后一反应则为不可逆反应,并消耗等分子的碱。因此,总的收率较高,以乙醛计>90%(摩尔%)。主要的副产物有聚季戊四醇、树脂等。理论上甲醛与乙醛的摩尔比应为4,实际生产中略大于此值。反应为放热过程,温度控制在≤60℃。反应液经蒸发、冷却,即得季戊四醇结晶。
季戊四醇主要用在涂料工业中,它是醇酸树脂涂料的原料,能使涂料膜的硬度、光泽和耐久性得以改善。它的松香酸酯用于制造清漆、地板漆、油墨等。此外,季戊四醇还用于制干性油和航空润滑油等。季戊四醇的四硝酸酯是一种烈性炸药──太安;其脂肪酸酯是高效润滑剂和聚氯乙烯增塑剂;其环氧衍生物则是生产非离子表面活性剂的原料。
