摘要
由甘油与硫酸作用制备丙烯醛 ,是早期广泛用于实验室的制备方法。鉴于硫酸是腐蚀性强酸 ,甘油在高温条件下与其作用制丙烯醛时炭化现象严重 ,影响产率。研究以硫酸氢钾与甘油作用制备丙烯醛 ,旨在克服炭化现象 ,提高收率。
Acrolein compounded by the reaction of glycerin and vitriol is an early way usedin the laboratory widely. Because vitriol is a kind of corrssive doughtyacid, it will be chared when glycerin reacting on the vitriol in a hightemperature. This phenomenon is very obvious,and it will affect the rate of production. This paper is about the acrolein compounded by the action of bisulfate-kalium in ofder to overcome the phenomenon and enhance the rate of production.
