現(xiàn)階段,在1,4丁炔二醇的合成和生產(chǎn)的過程中,主要的原料是乙炔和甲醛,采取的依然是炔醛法.由于工業(yè)電石產(chǎn)生的乙炔中,含有一定量的硫,磷以及砷等氫化物,在乙炔使用的過程中,必須對這些雜質(zhì)進(jìn)行清除.在1,4丁炔二醇生產(chǎn)工藝中對乙炔進(jìn)行凈化通常采用的是高濃度硫酸凈化的方式.由于該項工藝比較復(fù)雜,廢棄硫酸難以處理,審核的手續(xù)比較復(fù)雜,而且處理的成本比較高.因此,需要對其凈化的新方式進(jìn)行探究

At present, in the synthesis and production of 1,4-butynediol, the main raw materials are acetylene and formaldehyde, and the acetylene aldehyde method is still adopted Due to the presence of certain amounts of sulfur, phosphorus, arsenic and other hydrides in acetylene produced by industrial calcium carbide, these impurities must be removed during the use of acetylene The purification of acetylene in the production process of 1,4-butynediol is usually carried out using high concentration sulfuric acid purification Due to the complexity of the process, it is difficult to dispose of waste sulfuric acid, the audit procedures are complicated, and the cost of disposal is relatively high Therefore, it is necessary to explore new ways of purifying it
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Application of Shimadzu Column for 1.4-butanediol Detection Chromatography" with high column efficiency and good separation. It has achieved good results on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE.
