3synthesis methods
-

Yield:2915-52-8 95%

Reaction Conditions:

with dibutyltin dilaurate in water at 110; for 1.5 h;

Steps:

Synthesis

Dodecyl maleate diester, as a reference product for thermo-gravimetric analysis was synthesized in bulk. 1-dodecanol (26.67 g,0.14 mole) was introduced in three-necked flask fitted with a con-denser and heated at 110C. After melting the alcohol, maleicanhydride (7.02 g, 0.07 mole) was added. Dibutyltin dilaurate(100 mg, 0.158 mmol) as a catalyst was added. The reaction mix-ture temperature was maintained at 110C and stirred for 60 min.Low pressure (0.5 bars) was applied for 30 min in order to removeresidual water. Product was recrystallised from methanol. Whitecrystals of di-dodecyl maleate (30.92 g, 95%) were obtained 1HNMR (300 MHz, CDCl3, 20C) (ppm): 0.88 (6H, t, CH3), 1.26 (36H,m, CH2), 1.67 (4H, m, CH2), 4.17 (4H, t, CH2), 6.26 (2H, s, CH).
