Toluene insoluble material experiment apparatus and toluene recovery method

Abstract

The invention discloses a toluene insoluble material experiment apparatus with recovery function. The apparatus comprises a liquid adding device, a recovering device, a waste gas filtering device andan experiment device, wherein the experiment device comprises a condensing device, a reaction device and an evaporation device, the condensing device is connected to the reaction device, the reactiondevice is connected to the evaporation device, the liquid adding device and the recovering device are connected to the experiment device, the experiment device is arranged in a reaction bin, the outershell of the experiment device is provided with a liquid adding port, and the reaction bin and the recovering device are connected to the waste gas filtering device. According to the present invention, the apparatus has the simple structure, and can filter volatile gases in the reaction chamber and other spaces so as to avoid the unorganized discharge; and the multiple apparatuses can be subjected to modularized connected in parallel, such that the requirements on the operator are greatly reduced, and the whole process is completely automated in the experiment so as to reduce the toluene solvent contact time of the personnel, protect the health of the operator and provide the important effect in occupational disease protection.

Description

technical field [0001] The invention belongs to the field of analytical instruments, and in particular relates to a toluene insoluble experimental device with a recovery function and a toluene recovery method. Background technique [0002] In existing technical standards, when operating insolubles and solubles experiments using toluene solution as a solvent, each experiment will add toluene solution that meets the standard liquid level in the reaction vessel as a dissolving solvent. The mixed solution containing toluene solution and the mixture of toluene solution has no ability to recover the toluene solution in the remaining liquid in the prior art. After continuing to use the mixed liquid for toluene dissolution experiments for several times, the mixed solution will be discarded, and some even The mixed liquid is directly discarded after one experiment, which not only causes a waste of experimental resources, but also the processing and production of the toluene solution ...
