Diethyl maleate is a versatile chemical compound with a wide range of industrial applications. Prepared by reacting maleic anhydride with ethanol, it exists in two isomeric forms: cis and trans structures. The quality of this compound is often assessed through key indicators such as total ester content, acid value, and water content. This article aims to delve into the diverse applications of diethyl maleate, including its role in the synthesis of polyaspartic polyurea, plant growth regulators like Calcium cyclamate, and more. Feiyang has 30 years of experience in manufacturing and marketing diethyl maleate, for more information please visit Diethyl Maleate.
Understanding the quality metrics of diethyl maleate is crucial:
In polyaspartic polyurea production, diethyl maleate is indispensable. This application has stringent requirements for acid esters but is more lenient on other quality indicators.
For Calcium cyclamate, a plant growth regulator, the diethyl maleate used must meet the following criteria:
Although largely banned, Malathion, a pesticide, still finds use in some parts of Africa.
2-Naphthylamine-3,6,8-trisulfonic acid, commonly known as “K acid,” is an organic compound used as a dye intermediate. It is crucial in the production of various dyes, pigments, and colorants for industries like textiles, leather, and paper. K acid is renowned for its excellent light fastness and high tinting strength. In the synthesis of K-Acid, an intermediate of Coragen, diethyl maleate is used in a cyclization reaction, achieving a yield of 60%-65%.
Requirements of this product for the index of diethyl maleate:
Coragen (20% Chlorantraniliprole Suspension)
Coragen is an insecticide developed by DuPont, with chlorantraniliprole as its active ingredient. It is registered for use on lawns, ornamentals, and various food and feed crops. Diethyl maleate serves as an intermediate in the production of Coragen, further showcasing its versatility.
Diethyl maleate is more than just a chemical compound. It’s a multifaceted ingredient with a broad spectrum of applications. From Polyaspartic polyurea to plant growth regulators and from dye intermediates like K acid, its utility is vast and varied. As we continue to explore its potential, diethyl maleate is poised to remain a cornerstone in various chemical applications for years to come.
