Described 1, the 2-ethylene dichloride is a technical grade.
Second purpose of the present invention finished by following technical proposal: a kind of method of extracting montan wax is characterized in that through the following step:
A, be 10～50% (weight) with brown coal drying to water content, be crushed to granularity≤2mm, cross 60 mesh sieves, sieve removes coal dust, granularity is that the coal grain of 0.2～2mm is standby;
B, in steps A gained coal grain, press the coal grain: the mass/volume ratio of solvent=1: 1～1: 3 adds the solvent of technical grade concentration, extraction 30min～5h, wherein, extraction solvent adopts the solvent of following volume ratio: 1, and the 2-ethylene dichloride: alcohol=3: 7～10: 0 gets extraction liquid, get filtrate and filter residue after the filtration, filter residue with an amount of and extraction phase with solvent wash after, with washing lotion and filtrate merging, abandon filter residue;
C, step B gained amalgamation liquid is concentrated into solvent-free steaming, reclaim solvent after, with the wax liquid injection dish of remainder, under 100～130 ℃ of temperature oven dry to removing moisture content and solvent, be cooled to room temperature afterwards after, brown coal wax;
After adding an amount of neat solvent allotment in D, the solvent after recovery, recirculation is used for the extraction of montanin wax.
The mass/volume of described B step is than being kg/L, perhaps g/ml.
The extraction of described B step is the conventional extraction processes of prior art, and extraction equipment also is the conventional equipment of prior art.
The conventional filtration method that is filtered into prior art of described B step, transition also are the conventional equipment of prior art.
The conventional concentration method of the simmer down to prior art of described C step, thickening equipment also are the conventional thickening equipment of prior art.
The present invention compared with prior art has following advantage and effect, after adopting such scheme: can be under same working condition, make the montanin wax productive rate than the raising of benzene formulation 2～3 percentage points, and the solvent for use cost than the reduction of benzene formulation 10～20%, and extraction gained montanin wax color is more shallow, be brown, quality is good, the extraction solvent that the present invention uses is free from environmental pollution, does not damage the healthy of people, and technology of the present invention desolventizes uses instead outside the nontoxic solvent that the invention provides, need not to change existing production unit and processing condition, can realize saving energy and reduce the cost, improve the quality of products, purpose free from environmental pollution.
