Abstract

The invention discloses a toluene insoluble substance measuring device which comprises an extraction cylinder and a beaker, wherein the extraction cylinder is connected with the beaker; a sealing element is arranged above the extraction cylinder; a liquid inlet is formed in the sealing element, and is connected with a liquid feeding device. The toluene insoluble substance measuring device disclosed by the invention can meet the requirements on measurement of a toluene insoluble substance and intensively realizes functions of liquid feeding, heating, stirring, filtration experiment and the like; moreover, the toluene insoluble substance measuring device is simple and reliable in structure, the requirements on an operator are greatly reduced, the experimental period is greatly shortened, the work efficiency is improved, and simultaneously, the operator is prevented from the contact with chemical reagents for a long time so as to ensure the safety of the operator.

Description

technical field [0001] The invention belongs to the field of instrument analysis, in particular to a device for measuring toluene insoluble matter. Background technique [0002] Different uses of asphalt have different requirements for asphalt quality. Coal tar pitch is used as binder and impregnating agent in the field of coal electrode and refractory material industry. Toluene insoluble (T.I) index plays an important role in evaluating whether coal tar pitch can be applied in these fields. When coal tar pitch is used as a binder, the coal tar pitch should contain as high a degree of residual coke in the form of carbon as possible. [0003] At present, the determination method of toluene insolubles is a purely manual method for experimentation, which requires operators to contact toluene and samples for a long time and manual operation to complete the experiment. As we all know, toluene is a volatile and toxic substance. Direct contact with toluene not only causes waste o...
