摘要
本文介绍了一种用H^+式强酸性阳离子交换树脂与OH^-式强碱性阴离子交换树脂,按1:1提纯甲醛;并用适当浓度的盐酸和氢氧化钠分别浸泡处理H^+树脂与OH^-树脂,使其再生.此法比精馏法优越.
This artide introduce a way-use iontropic exchange resin purifiedtion industry grade formaldehyde which can produce reagent formaldehyde. This way not only produce good quality, but also the process control and flow can finish in short period. It can make products safety and can be operated easily.
