| | Diallyl maleate Usage And Synthesis |
| Chemical Properties | colorless liquid with a pungent odor. | | Uses | An agent for the promotion of branching in emulsion polymers | | Uses | Diallyl maleate has potential applications in polyester resins, adhesives, and ion exchange resins. When used at low levels, Diallyl Maleate is an effective agent for the promotion of branching in emulsion polymers. | | Preparation | Diallyl maleate is obtained by the sulfuric acid-catalyzed esterification of maleic anhydride with propyl alcohol. | | Safety Profile | Poison by ingestion and
intraperitoneal routes. Moderately toxic by
skin contact. A skin and eye irritant. When
heated to decomposition it emits acrid
smoke and irritating fumes. See also ALLYL
COMPOUNDS and ESTERS. | | Synthesis | A typical procedure for the synthesis of diallyl maleate from maleic anhydride and acryl alcohol is as follows: maleic anhydride (1 mmol, 0.15 g), acryl alcohol (5 mmol, 0.46 mL, 0.37 g), and HFDAIL as a catalyst (10 mol/mol of maleic anhydride, 0.05 g) were charged into a 50 mL round-bottomed flask equipped with a Dean-Stark device, reflux condenser, and magnetic stirrer in a 50 mL round bottom flask. The reaction mixture was stirred at 125 °C for 7 hours. The progress of the reaction was monitored by thin layer chromatography (TLC) using ethyl acetate/hexane (2:8) as eluent. When TLC showed that the reaction was complete, the isolated product (diallyl maleate) was obtained by extraction with ethyl acetate (3 x 5 mL) and evaporation of ethyl acetate under reduced pressure to give the target product as a yellow oily liquid in 95% yield (0.26 g, boiling point = 340 °C). The resulting product was dried under vacuum at 70 °C for 5 hours. The viscous ionic liquid can be directly reused without further treatment after removing water under vacuum at 80 °C for 5 h. The product was dried under vacuum for 5 h at 70 °C. | | References | [1] Journal of Molecular Liquids, 2017, vol. 227, p. 153 - 160
