Abstract
The invention relates to a method for recovering and utilizing an organic solvent, which comprises the following steps of: (1) using activated carbon to perform the absorption pre-treatment of a usedorganic solvent, wherein the weight ratio of the activated carbon to the organic solvent is 0.1 to 0.5: 1; (2) filtering to remove the activated carbon to obtain the pre-treated organic solvent; and (3) recovering the organic solvent from the pre-treated organic solvent through purification. Compared with the prior art, the method for recovering and utilizing the organic solvent has a reasonable process, utilizes the cheap activated carbon to pre-treat the organic solvent firstly, then performs recovery treatment after partial impurities are absorbed, has simple operation, and has the advantages of environmental protection, economization and the like.
Description
Technical field
The present invention relates to organic solvent, relate in particular to a kind of organic solvent recoverying and utilizing method.
Background technology
During modern industry is produced in a large number with an organic solvent, particularly alcohol, acetone, ether etc., these organic solvents contain more impurity after use, can't directly utilize again, also be unfavorable for reclaiming, if the organic solvent after still using is dealt with improperly, can cause great harm to environment, also can cause the resource significant wastage, therefore, must carry out necessary processing the organic solvent after using.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of technology organic solvent recoverying and utilizing method reasonable, simple to operate for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of organic solvent recoverying and utilizing method is characterized in that, this method may further comprise the steps:
(1) with active carbon the organic solvent after using is adsorbed preliminary treatment, the weight ratio of active carbon and organic solvent is 0.1～0.5: 1;
(2) filter, remove active carbon, obtain pretreated organic solvent;
(3) pretreated organic solvent reclaims organic solvent by purifying.
Described organic solvent comprises ethanol, methyl alcohol, ether, ethyl acetate, acetone.
The method of described purification comprises decompression distillation, rectifying.
Compared with prior art, organic solvent recoverying and utilizing method technology of the present invention is reasonable, utilizes cheap active carbon that organic solvent is carried out preliminary treatment earlier, recycles behind the absorbed portion impurity again, and is simple to operate, has advantages such as environmental protection, saving.
