Kipp's generator

Abstract

The invention belongs to the technical field of chemical experimental instruments, and particularly relates to a Kipp's generator. The Kipp's generator comprises a reaction vessel provided with an opening and a gas guide pipe communicated with the reaction vessel, wherein a rotary piston is arranged on the gas guide pipe; the Kipp's generator further comprises a separating funnel; the opening end of the reaction vessel is covered with a rubber stopper; the bottom end of the separating funnel penetrates through the rubber stopper and extends into the reaction vessel; a solid accommodating bottle is arranged in the reaction vessel, a plurality of through holes are formed in the bottom and the side part of the solid accommodating bottle, and the solid accommodating bottle is communicated with a feeding pipe; the top end of the feeding pipe penetrates through the rubber stopper and extends out of the reaction vessel; and the top end of the feeding pipe is covered with a rubber plug, the part, extending out of the reaction vessel, of the feeding pipe is enclosed, and a pressure meter is arranged at the part. The Kipp's generator is simple in structure, lower in preparation cost and capable of accurately observing conditions of pressure inside the reaction vessel, so that the pressure inside the reaction vessel can be well controlled, the reaction can be performed smoothly, and safety of an operator is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of chemical experiment instruments, in particular to a Kip generator. Background technique [0002] At present, the Kipp generator commonly used in the laboratory is mainly composed of a spherical funnel, a reaction vessel and an air duct, wherein the spherical funnel is placed on the top of the reaction vessel and penetrates into the reaction vessel, and the air duct is located at the upper sphere of the reaction vessel. A rotary piston is arranged on the air guide tube. [0003] In the existing Keppel generator, the pressure in the reaction vessel is controlled by the rotary piston on the gas guide tube, the pressure in the reaction vessel is unpredictable, and when the gas pressure in the reaction vessel is too high, the liquid will be pressed back into a spherical shape The funnel separates the reaction liquid and the solid reactant, the reaction will stop, and even cause the reaction vessel to explode;...
