Methyl Ethyl Ketone Peroxide(MEKP):A Comprehensive Overview
Introduction
Methyl ethyl ketone peroxide(MEKP),also known as methyl ethyl ketone peroxide catalyst,is a potent organic peroxide widely used in various industrial applications.This article delves into the properties,production,and uses of MEKP,providing a detailed understanding of its significance in the chemical industry.
Physical and Chemical Properties
MEKP,with the chemical formula C8H18O6,is a colorless-to-faintly-yellow liquid that is highly reactive.It has a density of 1.16g/cm³,a melting point of 110°C,and a boiling point of 304.9°C at 760 mmHg.The闪点 of MEKP is 138.2°C,and it has a water solubility of 0.1-0.5 g/100 mL at 22°C.Its refractive index is 1.454,and it is stored under conditions of 2-8°C to maintain stability.
Production and Catalyst Role
MEKP can be produced by the reaction of hydrogen peroxide with methyl ethyl ketone or by autoxidation.The industrial process involves the addition of 70%hydrogen peroxide to a solution containing dibutyl phthalate,methyl ethyl ketone,and 65%HNO3 at a temperature of 30°C for a duration of 1 hour.The reaction solution is further stirred for an additional 30 minutes at the same temperature.
In the production of MEKP,catalysts play a crucial role.The traditional production process uses inorganic acids such as sulfuric acid and phosphoric acid as catalysts.However,these acids can be corrosive to equipment and require neutralization,generating a large amount of wastewater.Recent studies have focused on heterogeneous catalytic synthesis of organic peroxides,such as using UiO-66 as a catalyst,which offers a new multiphase catalytic pathway for the synthesis of peroxides.
Uses and Applications
MEKP is primarily used as a curing agent for unsaturated polyester resins and vinyl ester resins.It is also used as an organic synthetic initiator,bleaching agent,and fungicide.Due to its high reactivity,MEKP is available only as a 40%to 60%solution in dimethyl phthalate or other phthalates.It offers the greatest flexibility in terms of useful concentration range and pot-life,finding use in a wide variety of ambient temperature cure applications.
Safety and Regulatory Information
MEKP is classified as an oxidizing and corrosive substance,with risk terms including R7(may cause fire),R22(harmful if swallowed),and R34(causes burns).Safety terms include S14(keep away from(incompatible materials)storage),S26(in case of contact with eyes,rinse immediately with plenty of water and seek medical advice),and S36/37/39(wear suitable protective clothing,gloves,and eye/face protection).
Regulatory information for MEKP includes its listing on the U.S.Environmental Protection Agency's Title III Consolidated List of Lists,with a CERCLA RQ of 10 pounds.It is also included in the OSHA Process Safety Management(PSM)Standard List,with a Threshold Quantity(TQ)of 5000 pounds for concentrations greater than 60%.
Economic Aspects
The global consumption of ketone peroxides in the plastics sector reached approximately 60,000 metric tons in 2016,accounting for 25%of the total peroxide consumption within the plastics industry.This indicates the significant economic impact of MEKP and its derivatives in the global market.
Conclusion
Methyl ethyl ketone peroxide(MEKP)is a versatile chemical with a wide range of applications in the plastics,coatings,and adhesives industries.Its production and use are regulated due to its hazardous nature,and ongoing research is focused on developing more sustainable and safer methods for its synthesis.As the demand for MEKP continues to grow,so does the need for innovative solutions to ensure its safe and efficient use.
