    Methyl cinnamate

化合物简介

Methyl cinnamate is the methyl ester of cinnamic acid and is a white or transparent solid with a strong, aromatic odor. It is found naturally in a variety of plants, including in fruits, like strawberry, and some culinary spices, such as Sichuan pepper and some varieties of basil. Eucalyptus olida has the highest known concentrations of methyl cinnamate (98%) with a 2-6% fresh weight yield in the leaf and twigs.

生产方法及用途

生产方法
由肉桂酸与甲醇酯化而得。将肉桂酸、甲醇和硫酸的混合物加热回流5h,加收过量的甲醇。冷却,分去酸层,水洗后再用10%碳酸钠溶液洗涤,然后用水洗至中性。得粗品,经重结晶或减压蒸馏[收集132-134℃(2.0kPa)馏分],得肉桂酸甲酯成品。收率约70%。 添加到肥皂,香水和化装品,香精香料原料。
用途
添加到肥皂,香水和化装品,香精香料原料。
