浆纱油剂的水分定量和石蜡检测分析

Water Quantitative Analysis and Wax Detection of Size Oil

运用烘燥失重法和恒沸蒸馏法定量测定了浆纱油剂中的水分含量 ,烘燥法水分直接在 10 5℃下除去 ,恒沸蒸馏法水分与甲苯一起馏出分离 ,比较而言 ,烘燥失重法测定方便。用皂化分解法建立了浆纱油剂中石蜡成分的检测方法 ,并用红外光谱分析验证了该方法的可靠性。

With loss of weight byven dry and constant boiling distillation, the water content are quantitatively tested, In oven method, the water is drying out directly in 105 ℃,and in constant boiling distillation, water is fractionated out together with the toluene. Comparatively, oven method is handy for water detection. With decomposition of saponification, the detection method of wax content in size oil is constructed, and its reliability was demonstrated by the spectrum analysis of infrared.
