硬脂酸盐生产皂化终点的研究

Study of the End Point of Soap Flake of Producing Stcarate

通过实验和理论分析,证明了硬脂酸盐皂化终点与硬脂酸盐的质量(金属含量、熔点、游离酸、热稳定性)有密切的关系,得出硬脂酸盐生产皂化终点NaON必须微过量才能确保产品的质量,并采用了中性乙醇—HCI标液滴定法对皂化终点进行定量分析。

Through the experience and theoretical analysis, this paper proves the relation between the end point of stearate soap flake and the mass of stearate (such as metal content melt point, free acid, heat stability) . It concludes that only with excessive NaOH at the end point of stearate soap flake can the quality of product be approved. This paper use the way of normal ether - HC1 standard solution to quantitative titrimet analysis soapflake.
