Abstract

Vinyl acetate, as an important kind of organic chemical raw materials, often adopts the distillation system to separate finished product from raw product. In addition to target products, some residues are produced in the process of distillation, which have a strong damage to the environment, therefore these residues are identified as hazardous wastes to manage and dispose in China. This paper, combined with literature analysis and site investigation, mainly studied production characteristics and particular pollutants of vinyl acetate distillation residue (solid and liquid). To conduct the analysis of the physical and chemical properties of distillation residue, and this paper applied the Gas chromatography-Mass spectrometry (GC-MS) to detemine main particular pollutants, containing Acetic Acid (relative peak area value of 63.47%), 1,1-Ethanediol Diacetate, Crotonic Acid, etc. Meanwhile, this paper can draw another conclusion that treatment and disposal of resource utilization distillation can make more significantly and efficiently use of vinyl acetate distillation residues through the technological contrast of GC-MS.
