Designing greener plasticizers: Effects of alkyl chain length and
Di (2-ethylhexyl) maleate (DEHM) and dibutyl maleate (DBM) are commercially available compounds, used as a secondary plasticizers and in applications such as coatings and adhesives in the case of DEHM and films in case of DBM (Wypych, 2012, Wypych, 2013).
Mechanical and thermal properties of poly (lactic acid) plasticized
The purification followed the same procedure described above for dibutyl maleate affording dibutyl fumarate (11.7 g, 0.0510 mol) in 50% yield. 2.3. Plasticized mixtures and film preparation PLA/plasticizer mixtures were prepared, and the film sequentially produced by thermopressing.

Maleic Acid Dibutyl Ester (DBM) Page 1 of 4 Maleic Acid Dibutyl Ester Dibutyl Maleate CAS no. 105-76-0 EC no. 203-328-4 Product description Maleic acid dibutyl ester is a clear, virtually colourless liquid with an ester-like odour. It is miscible with, for example, methanol, ethanol, acetone, diethylether, N, N-dimethyl formamide and toluene,
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 is dibutyl maleate (DBM) used for?
- Dibutyl maleate (DBM), an unsaturated ester produced with the reaction of maleic acid and n-butanol, is used for creating sulfosuccinate surfactants in detergents and paints. Esterification is a prime reaction having wide applications in the production of flavors and fragrances, solvents, plasticizers, pesticides, and herbicides.
- What is dibutyl maleate used for in paints?
- Dibutyl maleate (DBM) is used for creating sulfosuccinate surfactants in detergents and as a comonomer in emulsion polymerization for paints and adhesives. It is an unsaturated ester produced with the reaction of maleic acid and n-butanol.
- How does dibutyl maleate affect crystallization temperature?
- Increasing concentrations of dibutyl maleate (DBM) or dibutyl fumarate (DBF) lead to a decrease in the crystallization temperature, displacing Tc from 95 °C for neat PLA films to 75 °C in PLA-DBM-7, 70 °C in PLA-DBM-12, and other temperatures in other concentrations.
- How does dibutyl maleate affect glass transition temperature?
- The glass transition temperature (Tg) of PLA decreases with increasing content of dibutyl maleate (DBM). The Tg for neat PLA was 58 °C, decreasing to 37 °C in PLA-DBM-7 and 35 °C in PLA-DBM-12.
- Are dibutyl maleate and fumarate biodegradable alternatives for plasticization?
- Recent reports indicate dibutyl maleate (DBM) and derivatives of fumarate as promising biodegradable alternatives for plasticization. Derivatives of maleate (cis) and fumarate (trans) have shown differences in plasticization of PVC.
- Is dibutyl maleate biodegradable?
- Dibutyl maleate has been shown to be biodegradable. It demonstrated ready biodegradation in a microcosm test using aerobic sludge and biodegradation with a half-life of 8.9 days when tested with Rhodococcus rhodocrous.
