摘要
三氯乙酸生产工序排放的废硫酸因含醛高而多次发生二次污染现象。本文通过生产实验 对含醛废硫酸的脱醛技术进行了两种工艺路线的探讨。效果显著。
During the production of trichloroacetaldehyde, waste surfuric acid as the by-products would causes second pollution due to its high aldehyde-content.Two kind of technologies of dealdehyding which have high productivity in the production,have been studied based on the experiment in this paper.
