摘要
采用SH/T 1591-94检测乙酸乙烯酯(VA)含量时,氢氧化钾-乙醇标准溶液的含水量是影响测定结果的主要因素。对影响因素进行了定量研究,结果表明,配制氢氧化钾-乙醇标准溶液时,加水量宜控制在6％以下。
When the vinyl acetate content is determined using SH/T 1591 -94, the amount of water in potassium hydroxide-enthanol standard solution is the primary factor influencing the measuring result. The influencing factor was studied quantitatively. The result showed that the amount of water was suitably controlled under 6% when making up the potassium hydroxide-enthanol standard solution.
