Cr_2O_3替代铬铁矿制备重铬酸钾的实验研究

Experimental Study on the Preparation of Potassium Dichromate With the Alternative of Cr_2O_3 to Chromite

探究了Cr2O3与KCl O3的不同物料配比在不同碱熔性环境中,制备重铬酸钾的条件,实验表明:在Na OH和Na2CO3混合物的碱熔性条件下,Cr2O3与KCl O3物质的量比为1:1.5时,达到较好的转化率。

This article explores the preparation conditions of potassium dichromate from Cr2O3 and KCl O3 of different material ratios in different alkali fusion evironments. The experiment shows that a better conversion rate is achieved,in Na OH and Na2CO3 melt mixture,setting the molar ratio of Cr2O3 and KCl O31： 1. 5.
