Articles：

150 and 300mL beaker each, a glass bar, alcohol lamp, asbestos net, tripod, lard (or other animal or vegetable fats or oils), NaOH, 95% alcohol, saturated salt water.

The operating：

(1) In the 150mL beaker, 6g of lard and 5mL 95% alcohol, then add 10mL40 % NaOH solution. Stir with a glass rod to dissolve it (heating with a small flame if necessary). (2) Place the beaker on the asbestos (or water bath), heat it with a small fire and keep stirring it with glass. In the heating process, if the alcohol and water are evaporated, the reduction should be added at any time to maintain the original volume. The mixture of alcohol and water can be prepared in advance (1:1) 20mL in preparation. (3) After heating about 20 min, the saponification reaction was basically complete. If the test is to be tested, a few drops of glass can be removed and put into the test tube. In the test tube, add the distilled water to 5 ~ 6mL and heat the oscillation. When static, there is oil separation, indicating that saponification is not complete, but the drip and lye continue to saponify. (4) Slowly add the distilled water of 20mL of heat to the saponification of the completely viscous liquid, stirring to make them mutually soluble. Then slowly pour the thick liquid into a saturated salt solution of 150mL heat. Stir and stir. After static setting, the soap will float on the surface of the soap, and then the soap will be taken out after the soap has been set up.
