Abstract
The invention relates to a novel dissolving procedure of a production technology of refined anthracene. The novel dissolving procedure of the production technology of the refined anthracene is characterized by comprising the steps of loading crude anthracene into a dissolving pan filled with a polar solvent A by an elevator, and then opening a steam valve in a dissolving pan jacket to perform indirect heating on the crude anthracene. The dissolving procedure has the advantages that the product purity is high; a recovery rate is high; the purity of the refined anthracene is not less than 96%; the recovery rate is generally greater than 90%; the purity of refined carbazole is not less than 95%; a yield of anthracene oil is above 60%; and the dissolving procedure is wide in raw material scope, low in operating temperature and high in automation degree.
Description
Technical field
The present invention relates to a kind of dissolution process of production technique of novel anthracene, belong to field of fine chemical.
background technology
Current domestic enterprise mostly adopt carbolineum is cooled, the method for crystallization and centrifugation produces crude anthracene, then takes solvent extration or solvent distillation method to produce anthracene and carbazole.The working method technics comparing of domestic carbolineum falls behind, and processing power is little, and energy consumption is high, contaminate environment, deficiency in economic performance.
Summary of the invention
Object of the present invention overcomes the deficiency of above technology, provides a kind of dissolution process of production technique of novel anthracene.Be achieved through the following technical solutions for achieving the above object: the dissolution process that the present invention relates to a kind of production technique of novel anthracene, it is characterized in that the first step operation of the dissolution process of the production technique of described a kind of novel anthracene is that crude anthracene is sent into the dissolving pan that polar solvent A is housed by lift, the steam valve opened after feeding intake in dissolving pan chuck carries out indirect heating to it.The second step operation of the dissolution process of the production technique of described a kind of novel anthracene starts the agitator in dissolving pan, when material temperature reaches 110 DEG C, stops heating, be incubated 60 minutes, then will dissolve compound completely and send into extraction pot.
advantage of the present invention is:
Product purity is high, and the rate of recovery is high, and the purity of anthracene is not less than 96%, and the rate of recovery is generally greater than 90%; To the yield of carbolineum more than 60%; Wide scope of material, service temperature is low.Level of automation is high.
embodiment explanation
tell about embodiment below:
embodiment 1:a kind of dissolution process of production technique of novel anthracene:
The present invention relates to a kind of dissolution process of production technique of novel anthracene, it is characterized in that the first step operation of the dissolution process of the production technique of described a kind of novel anthracene is that crude anthracene is sent into the dissolving pan that polar solvent A is housed by lift, the steam valve opened after feeding intake in dissolving pan chuck carries out indirect heating to it.The second step operation of the dissolution process of the production technique of described a kind of novel anthracene starts the agitator in dissolving pan, when material temperature reaches 110 DEG C, stops heating, be incubated 60 minutes, then will dissolve compound completely and send into extraction pot.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
