20201-24-5 - Introduction

Ethyl 3-methyll-2-oxobutyrate, also known as Methyl Ethyl Ketone Peroxide (MEKP), is an organic Peroxide. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: colorless liquid
-Density: 1.13g/cm³
-Boiling point: 101 ° C
-Flash Point: 16 ° C
-Soluble in organic solvents such as ethanol, ether and acetic acid

Use:
- MEKP is usually used as an initiator or catalyst, mainly used in peroxide reactions such as polymer curing, resin crosslinking and Adhesive curing.
-It is commonly used in the production of glass fiber reinforced plastics, resin coatings, ink, glue, polymer foam and plastic products.

Method:
- MEKP is generally prepared by reacting hydrogen peroxide with butanone under acidic conditions.

Safety Information:
- MEKP is a toxic, irritating and flammable substance and should be handled with care to avoid direct contact with skin, eyes and mucous membranes.
-High concentrations of MEKP vapor can cause the inhalation of irritating gases or vapors, which may cause respiratory system discomfort.
-When using or storing MEKP, avoid contact with acid, alkali, metal powder and other flammable substances to prevent fire or explosion.
-It should be used in a well-ventilated area and use appropriate personal protective equipment, such as chemical gloves, protective glasses and respiratory protectors.

Before using MEKP, be sure to understand relevant safety information and operating procedures, and take appropriate safety precautions to reduce potential hazards.
