Rotary evaporator for preparing brominated epoxy resin

Abstract

The invention discloses a rotary evaporator for preparing brominated epoxy resin, wherein the rotary evaporator comprises a rack. The upper end of the rack is equipped with a condenser, the lower endof the condenser is connected with a gas pipeline, the lower end of the gas pipeline is equipped with an evaporation bottle, the inner wall of the evaporation bottle is equipped with a temperature sensor, the outer wall of the evaporation bottle is tightly jacketed with an electric heating piece, and the electric heating piece is externally sleeved with a heat shield cover; the lower end of the rack is equipped with a processor electrically connected with the temperature sensor and a displayer electrically connected with the processor; the middle part of the rack is equipped with a battery. The rotary evaporator has the beneficial effects that the rotary evaporator for preparing the brominated epoxy resin does not need water bath heating and the assistance of water cooling devices during working, has fewer supporting devices and low use cost, significantly reduces the production cost of brominated epoxy resin production enterprises, and has good practicability.

Description

technical field [0001] The invention relates to the field of brominated epoxy resin preparation, in particular to a rotary evaporator for preparing brominated epoxy resin. Background technique [0002] Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat at a constant temperature under vacuum conditions to make the rotary bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall and evaporates efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easy to decompose and denature at high temperature. However, the common rotary evaporators currently on the market still have the following pr...
