Paragraph 0024; 0026; 0027; 0028, (2018/11/04)
The invention provides an allyl amyl glycolate preparation method, wherein specifically a reaction is performed by replacing the conventional allyl alcohol with vinyl chloride to prepare allyl amyl glycolate. According to the present invention, the method has advantages of simple operation, high yield, high purity, greatly reduced production cost, reduced waste generation and reduced environmentalhazard, wherein the excess vinyl chloride residue in the final product cannot be generated.
Synthesis of unsaturated esters via highly efficient esterification catalyzed by polymer grafted quarternary ammonium salts as triphase catalysts

, p. 1558 - 1561 (2013/09/12)
A series of unsaturated esters were prepared via condensation of sodium carboxylates and alkenyl halide under the condition of macroporous polystyrene grafted quarternary ammonium salt as recyclable phase transfer catalyst, NaI as co-catalyst, Cu powder as inhibitor and H2O as solvent. Under optimal conditions, products yields are 78.2～ 96.0%. The catalyst can be convenient recycled and reutilized for about five times without losing its activity obviously.
