Problems solved by technology

[0002] For the detection of butyl acrylate intermediate products, the Ukang chromatographic column used by the national standard is generally used at present, but the disadvantages of using the Ukang chromatographic column are: 1. After a period of use, the peak of acrylic acid will move forward after using the Ukang chromatographic column. The problem that it cannot be separated from butyl acrylate; 2. With the increase of use time, the data of the same sample will change, resulting in inaccurate and unstable test data, short service life, and may affect normal production

Abstract

A chromatographic column used for material detection in production apparatus of butyl acrylate. The invention belongs to the field of detection and analysis of butyl acrylate. An external tube is filled with a mixed filler that is a mixture obtained by uniformly mixing a first filler and a second filler according to the mass ratio of 98.3-99.4:1; a stationary liquid of the first filler is a reaction product of 20M polyethylene glycol and terephthalic acid, mass percentage of the reaction product being 4.8-5.2%, and an H3PO4 acetone solution being 0.48-0.52% in mass percentage; a stationary liquid of the second filler is a reaction product of 20M polyethylene glycol and terephthalic acid, mass percentage of the reaction product being 9.8-10.3%, and an acetone solution of polyneopentyl glycol adipate, of which the mass percentage is 9.8-10.3%. A carrier is a processed white diatomite carrier. The chromatographic column has high accuracy and long service life. The filler is stable and is not liable to lose. The chromatographic column provides accurate and reliable detection data for reducing material loss.

Description

technical field [0001] A chromatographic column used for material detection in a butyl acrylate production device belongs to the field of butyl acrylate analysis and detection.
