Example Embodiment
[0015] Example 1
[0016] A. Add 1000 g of crude montan wax containing 27.86% resin and 4000 g of technical grade ethyl acetate to the extraction reactor, heat to 72°C, and extract for 3 hours under stirring.
[0017] B. Cool the material to room temperature and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recover ethyl acetate to obtain a resin product, and the filter cake is again put into the extraction reactor for secondary extraction.
[0018] C. Add filter cake and 3000 grams of technical grade ethyl acetate to the extraction reactor, heat to 72°C, and extract for 3 hours under stirring.
[0019] D. Cool the material to room temperature, and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recover ethyl ace...

[0020] Example 2
[0021] A. Add 1000 grams of crude montan wax containing 27.86% resin and 3000 grams of technical grade butyl acetate into the extraction reactor, heat to 100°C, and extract for 3 hours under stirring.
[0022] B. Cool the material to room temperature and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recover butyl acetate to obtain a resin product, and the filter cake is again put into the extraction reactor for secondary extraction.
[0023] C. Add filter cake and 2200 grams of technical grade ethyl acetate to the extraction reactor, heat to 100°C, and extract for 3 hours under stirring.
[0024] D. Cool the material to room temperature, and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recov...
Example Embodiment
[0025] Example 3
[0026] A. Add 800 grams of crude montan wax containing 27.86% resin and 3000 grams of technical grade butyl acetate into the extraction reactor, heat to 80°C, and extract for 3 hours under stirring.
[0027] B. Cool the material to room temperature and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recover butyl acetate to obtain a resin product, and the filter cake is again put into the extraction reactor for secondary extraction.
[0028] C. Add filter cake and 2000 grams of technical grade butyl acetate to the extraction reactor, heat to 80°C, and extract for 3 hours under stirring.
[0029] D. Cool the material to room temperature, and continue to stir at room temperature for 0.5 hours. Then the solid-liquid separation is carried out by means of filter press. The resin-containing liquid phase is distilled to recover ...
