250 ml Reactor System

The reactor consists of a high‑temperature and corrosion‑resistant vessel, a highly efficient mixing agitator, a heating and cooling system with precise temperature control, a meticulously designed feed and discharge port, and safety‑enhancing accessories. Its operating principle involves the pre‑mixing of initiators and catalysts, vacuum dehydration, and nitrogen purging, followed by ring‑opening polymerization of the raw materials through agitation and temperature control to produce polyether compounds, while ensuring safe operation.

Product Description

Structure
Reactor vessel:
Stainless steel, titanium, and other corrosion‑resistant, high‑temperature‑resistant materials are often used to withstand high temperatures, high pressures, and chemical corrosion.
Mixing device:
It consists of a mixer and a搅拌 shaft. Common types of mixers include propeller-type and turbine-type mixers, which can ensure uniform mixing of reactants, enhance mass and heat transfer, and improve reaction efficiency.
Heating and Cooling Systems:
Generally, there are two types: jacketed reactors and internally coiled tube reactors. They control reaction temperature by passing heating media such as steam or thermal oil, or cooling media such as water, through the system.
Inlet and outlet:
It includes a feed inlet and a discharge outlet; the feed inlet typically has multiple ports, allowing for precise control of the proportions and addition sequence of different raw materials, while the discharge outlet is used to remove the final product.
Safety accessories: Such as safety valves and pressure sensors—safety valves can prevent excessive pressure inside the reactor from causing hazards, while pressure sensors monitor pressure data in real time.

Working Principle
In the operation of a polyether reactor, the initiator is first pre‑mixed with the catalyst to form metal alkoxide compounds. After vacuum dehydration, the mixture is fed into the reactor, and dry nitrogen is then introduced to displace the air inside the reactor and prevent oxidation. Subsequently, raw materials such as ethylene oxide and propylene oxide are added according to the specified proportions. A stirring device ensures thorough mixing of the reactants, while the heating and cooling systems precisely control the reaction temperature. Under optimal temperature and pressure conditions, the reactants undergo ring-opening polymerization to produce polyether compounds. Once the reaction is complete, the product is discharged through the outlet, after which the reactor is cleaned in preparation for the next batch.
