摘 要: | <正> 近来,林西平等研制成的 X 型催化剂是一种用淤浆态反应器中甲醛乙炔化的催化剂,其组份为 Cu-Bi-Al-O。因此,合成的丁炔二醇液体产品中铝含量的多少可用来衡量丁炔二醇产品的质量,并预报催化剂的寿命。关于该体系中铝的测定,我们在文献的基础上研究采用了 Al-CAS-CTMAB-C_2H_5OH 四元络合

The Determination of Trace Aluminium in Butynediol |
| |
Abstract: | In this paper,the determination of trace aluminium in butynediol,which was synthesized by an improved Reppe method using X-type catalyst,was carri-ed out by spectrophotometric analysis in CAS-CTMAB alcoholic system.Theprecision of this method is better than 1.5%,the rate of recovery is about 97to 99 per cent. |
