The effect of maleic acid diesters type on the stability of vinyl
Vinyl acetate (VAc) was copolymerized with two different maleic acid diesters, dibutyl maleate (DBM) and dioctyl maleate (DOM) at different comonomer ratios by semi-continuous emulsion polymerization method. The effects of maleic acid diesters type and amount on the latex properties of VAc emulsion polymers were investigated.
Designing greener plasticizers: Effects of alkyl chain length and
To enhance its mechanical, thermal and processability properties, at this study the authors use small molecules maleic acid (MA) and its propyl ester derivatives monopropyl maleate (MPM) and dipropyl maleate (DPM) as alternative plasticizers.
Esterification of maleic acid and butanol using cationic
Abstract Dibutyl maleate is a perfumery ester used as an intermediate in the production of paints, adhesives, and copolymers. Esterification of maleic acid and butanol was studied in presence of acidic cation exchange resin as a catalyst. The objective of this work was to test the suitability and efficacy of heterogeneous catalysts such as Indion 225H and Amberlyst-15 in the synthesis of

Dibutyl maleate
Dibutyl maleate is mainly used as a plasticizer for aqueous dispersions of copolymers with vinyl acetate and as an intermediate in the preparation of other chemical compounds. [5] With the invention of polyaspartic technology the material found another use.
- What are maleic acid esters?
- Maleic acid esters are known as maleates for example dimethyl maleate. There are wide to lesser applications of maleic acid. The major industrial utilization of maleic acid is in the production of fumaric acid. The conversion of maleic acid into fumaric acid is carried out by the isomerization process.
- How is dibutyl maleate prepared?
- Dibutyl maleate can be prepared by the reaction of maleic acid anhydride and 1-butanol in presence of p-toluenesulfonic acid. Dibutyl maleate is mainly used as a plasticizer for aqueous dispersions of copolymers with vinyl acetate and as an intermediate in the preparation of other chemical compounds.
- What is dibutyl maleate used for?
- Dibutyl maleate is mainly used as a plasticizer for aqueous dispersions of copolymers with vinyl acetate and as an intermediate in the preparation of other chemical compounds. With the invention of polyaspartic technology the material found another use.
- Is dibutyl maleate miscible?
- Maleic acid dibutyl ester (DBM) is a clear, virtually colorless liquid with an ester-like odor. It is miscible with methanol, ethanol, acetone, diethyl ether, N-dimethylformamide and toluene. Why Dibutyl Maleate?
- Can dibutyl maleate be used as a dienophile?
- Dibutyl Maleate production permits the addition reactions normally possible with compounds having olefinic double bonds and is suitable, for example, as a dienophile for diene syntheses using the Diels-Alder reaction.
- Which amine is reacted with a dibutyl maleate?
- In this situation, an amine is reacted with a dialkyl maleate - usually diethyl maleate but also dibutyl maleate may be used- utilizing the Michael addition reaction. The resulting products, polyaspartic esters products are then used in coatings, adhesives, sealants and elastomers.
