Introduction to Methyl Ethyl Ketone Peroxide (MEKP) Project:

Methyl ethyl ketone peroxide, also known as peroxy-2-butanone, abbreviated as MEKP, has a molecular weight of 178.21. It is a colorless transparent oily liquid with a relative density of 1.042 (15°C/4°C). It is stable at room temperature but explodes at temperatures above 100°C, with a flash point of 50°C. It is typically used as a 50%-60% solution of MEKP in dimethyl phthalate. MEKP decomposes at 105°C and is soluble in benzene, alcohols, ethers, and esters but insoluble in water. It is of low toxicity. When mixed with reducing agents, sulfur, or phosphorus, it forms explosive mixtures. There is a risk of combustion and explosion upon exposure to high temperatures or impact.

New Technology for Methyl Ethyl Ketone Peroxide:

Currently, the synthesis of methyl ethyl ketone peroxide (MEKP) mostly occurs in jacketed heat exchanger-type reactors. During production, the feeding rate needs to be strictly controlled due to the heat transfer limitations of the reactors. MEKP is a mixture of various MEK peroxide products containing -O-O- bonds, making it highly sensitive to heat, friction, vibration, and impact. This poses significant safety hazards during storage and transportation.

A continuous synthesis device for methyl ethyl ketone peroxide has been designed, making full use of the advantages of microchannel reactors, such as large surface area, strong heat transfer capabilities, good mixing performance, and precise control of residence time. This design avoids the safety issues associated with the preparation, storage, and transportation of MEKP.

The device integrates raw material mixing, peroxidation reaction, product separation, product dilution (using dimethyl phthalate as a solvent), and product clarification (using dimethyl phthalate as a clarifying agent). It forms a tabletop, movable, continuous, safe, on-demand, and on-site production-efficient MEKP continuous synthesis device. Production capacity: 10-1000 tons/year; Product specifications: active oxygen >11%, MEK concentration <1%.

Technological Application Prospects:

Methyl ethyl ketone peroxide (MEKP) is used as a room temperature curing agent for unsaturated polyester resins, an initiator for organic synthesis, a bleaching agent, and a bactericide. It is used as a catalyst in the production of polyesters and acrylic polymers and is the safest peroxide. It is also widely used as a curing agent in the production of reinforced polyester fiberglass. MEKP is commonly used as a curing initiator for unsaturated polyester resins.

This technology can replace existing MEKP production processes. Users of MEKPO can also utilize this technology for on-site synthesis, avoiding the risk of storing MEKP.
